Why is ammonia in gas form at room temperature?

User Avatar
That is because ammonia's boiling point is -33.34 Celsius or -28 Fahrenheit. The average household temperature is about 28 to 32 Celsius depending where you live but wherever it is, it is definitely above the boiling point of ammonia.

How will you justify water is a compound?

User Avatar
See related questions. Water is made up of elements Hydrogen and Oxygen with the chemical formula: H2O. It can easily be disassociated with electrolysis into the elements Hydrogen (H2) and Oxygen (O2), and reformed with combustion. It has aspects of both covalent and ionic bonds. It is generally considered neutral, but can be a proton donor to act as a weak acid. H2O --> HO- + H+. It can also act as a weak base, being a proton acceptor. H2O + H+ --> H3O+.

Adobe Creative Cloud Service / Program Download and Activation If you're a subscriber to Adobe's new Creative Cloud Service (where all of Adobe's flagship programs and more are available for download and use for a subscription fee) or you're subscribing to an individual product, your activation code is automatic after install once you sign up. There is no serial number. For those of you wondering whether it's worth subscribing or buying, Adobe's Cloud Service is outstanding. If you're a previous Adobe Suite customer, you can literally subscribe annually to the service and have access to more programs than you would if you just upgraded, and for about the same cost. That includes Master Collection users. The seat license number is the same though, for subscription or a copy you've purchased; 2 seats (computers) can have a single program activated at the same time. It doesn't matter how many systems you install a program on, but you can only have it activated on 2 systems simultaneously. Where is the Serial Number? For hard copy versions of Adobe programs, the Serial Number should be located on the DVD case or in your documentation (booklet) that came in the box. You will know it is your serial number because it is a long mix of numbers and letters separated by dashes that seem to make no sense at all, usually 16 characters. Each Adobe product has its own serial number - unless you have a Creative Suite in which case there will be one serial number for the whole suite, and each buyer will have a different serial number than another buyer. Note that just viewing the information in the program itself doesn't show the whole number; the last 4 digits are intentionally missing. Online Purchases Older programs and suites prior to CS2 will have SN's on the email invoice. CS3 programs and up will have the SN's and Activation Codes on the invoice, and in your online Adobe Account Download Manager (My Adobe). If you've purchased online through your Adobe account and the Adobe Store, your serials and activation codes will remain for as long as your account is active. I have serials and programs available going back over 10 years on my account, including pre-merger Macromedia titles and SN's. NOTE: While earlier CS versions (CS1 and 2) had a Master Serial, CS3-CS6 contain a Master Serial and individual program serial numbers for certain programs and suites packages. It is more typical in the Master Collection. Install Without Serial This serial number is necessary to install the retail version of your software. When installing the software, follow the on screen instructions. There will come a box that asks you for your serial number - this is where you will enter the number - and installation will continue. You can't use the software without installing it with a serial number. NOTE: Beginning with the release of Adobe CS3 programs, all serial numbers must now be Registered and each program Activated online at the Adobe site via the user's online Adobe account, and no more than 2 registrations per program/user will be allowed (2 system installation, e.g., notebook and desktop). If you wish to move a registered program from one system to another, you must first deactivate it from within the program (Help - Deactivate), install it on your new system, then re-activate it on the Adobe site again. Program Activation is necessary to complete the installation of all programs CS3 and above. With CS4/CS6 programs, Activation happens automatically during installation. See "Activation" below. What To Do If You've Lost Your Serial If you have lost your serial number, you will need to contact customer support services at Adobe. They will instruct you on how to obtain a new one if possible. You will probably need to have proof of purchase, such as a scan of the UPC code on the box or a copy of your original receipt from the purchase. If you are a registered Adobe site customer/user, and have purchased products or registered them on the Adobe site (something you should always do) then you can obtain your product serials from your Adobe online account. Login, go to your Account, and select Product Serial Numbers. What Is The Activation Number? Adobe's Program Activation feature has been implemented by Adobe to put a halt to widespread piracy of its programs. By rendering programs useless until registered and activated on the Adobe site, it makes it difficult, if not impossible, for the type of piracy experienced in the past. Those of us who spend thousands on their Adobe programs also benefit as Adobe can use money saved by this feature to put into program development. Activation numbers are different from program Serial Numbers in that Serial Numbers are in effect the product's legal license number identification. Activation numbers are used to activate and enable the program for use on a user's system. The program will not function unless properly activated using the correct number, and only 2 activations of the same program license (Serial Number) are allowed at any given time. This means you can have 2 copies running on separate computers, but if you want it to run on another one you have to deactivate one (from the Help Menu in the program). The program must also be activated again on the new system in order for it to work. For authorized program owners, if you attempt to activate on more than one 2 systems, the activation procedure will prompt you to deactivate one before continuing. The activation number that is generally asked upon the first time running an Adobe product is gathered by following the on-screen instructions. You can choose to get the activation by Internet, phone, or mail**. Internet is the quickest and easiest way to activate. For phone activation: there will be a phone number that is toll-free you must call, provide your serial number and the activation code in the box on your screen. You will then receive the activation key that you need to enter into the next box. You only have to do this procedure once for each Adobe product you installed, or once for all Adobe software in a purchased Creative Suite. **NOTE: As of the release of Adobe CS4 Applications, all Adobe Software programs are now required to be activated online via a registered Adobe User Account. Only older applications will continue to be supported by other methods of activation. For Downloaded program delivery, the Activation code is in your Email Receipt and on your Adobe account downloads section. For Boxed delivery by shipping, the code is on your invoice. If you lose the invoice, you'll need to contact Adobe with some proof of purchase - invoice or transaction number, etc. Since Adobe customers are assigned a number and your order history is recorded, it's usually not a problem. For those who are not the original owner, unless the original owner transferred the serial numbers of the program/s to you, you will not be able to obtain the code. Transferring Adobe Program Licenses Adobe allows the transfer of single or volume product licenses from an individual or business to another individual or business. There is a formal process that must be completed in order to complete the transfer. See the attached link, "Transferring Adobe Product Licenses" More Info WikiAnswers does not provide serial numbers for full version retail software. This is a form of piracy if you did not purchase the software and thus do not have a serial number to install the software. It is also illegal to obtain one from the Internet if you legally purchased your software but lost your original serial number (see above for contacting Adobe for a new one). It is also a form of piracy to use key generators (keygens) to create a serial number and cracks to bypass the need to use a serial number or to remove the time limit for trials. It is also illegal to download the software on the Internet anyway - except for the Trial versions offered on their site - in which case you still have to purchase a serial number to continue using it. Note: This is a catch-all question. Neither it nor its alternatives should be removed and it should remain protected. Please do not merge this question and/or its alternates to combine it with another catch all question.

Is magnesium hydroxide a solid?

User Avatar
hydroxides are insoluble with exceptions of Ba, Sr, Ca and all ions of group 1 with a hydroxide are soluble... therefore, magnesium hydroxide is a solid. The question of its solubility in anything does not relate to whether it is solid or not. Temperature is also involved. Magnesium hydroxide is a solid at "room temperature". Carbon dioxide is a gas at room temperature, but a solid at low temperatures.

They will remain separate, or distinct, in forms. It will not dissolve - only polar molecules dissolve in polar solvents. Non-Polar Solutes and Solvents are a different matter.

Name two compounds in unpolluted air?

User Avatar
Carbon Dioxide is present in unpolluted air. Methane (animals grazing literally fart this out) is also present and Nitrogen oxides formed when lighting strikes. The electrical discharge is high enough to cause oxygen and nitrogen to combine. It is basically a natural fertilizer In unpolluted air these compounds are present at levels of about 390 parts per million, 1.8 parts per million, and 1 part per billion respectively. The most abundant and most important compound in unpolluted air is ... water vapour -- present at levels which vary between about 0.1% and 5%, depending on temperature and humidity.

What are some products of combustion?

User Avatar
water, carbon dioxide, carbon monoxide (in incomplete combustion) There's also nitrogen oxides. Really, it depends on what you burn. A sulfur fire, a magnesium fire and a tire fire have radically different combustion products. <<>> when combustion occurs it's sometines useful to separate out the byproducts from the main products. For example, when oil is burnt, the main products are carbon dioxide and water. That means the heat energy comes from atomic bonds formed between the carbon and oxygen, and between the hydrogen and more oxygen. Those are main products, while byproducts are things like carbon monoxide, sulpur componds and nitrous oxides. They are unwanted products which can be removed by filtering the fuel and/or the exhaust gas.

What are the super phosphates?

User Avatar
superphosphates are water soluble fertilisers and are used extensively to promote root growth especially plants belonging to the clover family .They are manufactured by mixing finely ground rock phosphates with sulphuric acid (produced by burning sulphur and absobing the SO2 gas produced in water). The final product is a mixture of dicalcium phosphate and calcium sulphate. Brian Robertson New Zealand

How many atoms are present in two mole of H2O?

User Avatar
each mole of h2o molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms. Therefore, three moles of atoms make up one mole of hydrogen molecules. And, six moles of atoms make up 2 moles of h2o. There are 6.023E23 atoms in a mole. So, six moles of atoms is equal to 6(6.023E23) or 3.614E24 atoms Wouldn't that be 36.14? More precisely a mole is simply a term that denotes a particular quantity. Just as a dozen equals 12 of something a mole is a specific quantity of atoms a dozen trucks or a dozen cotton balls still equal 12 of each. So to it is with a mole. A mole is 6.0221367 X 10^23, or 6.0221367E23. To put that as a number most people recognize you take 6.0221367 and move the decimal point 23 places to the right. That makes a mole equal to 602,213,670,000,000,000,000,000 which, don't quote me, lol, I believe is in the sextillions. Whatever it is it is an extremely large number! People can sometimes get confused at this next step. Your question asked how many "atoms" are present in 2 mole of H2O. H2O is a molecule, the sum of 2 Hydrogen atoms and 1 oxygen atom. To draw a parallel think of it like this: how many tires are there in 2 dozen vehicles? It takes 4 tires per vehicle and 2 dozen cars are 24. 24 X 4 = 96. Same logic applies here because it requires 3 atoms to make one water molecule. 2 mole of water molecules are simple to equate. It is 6.0221367 X 10^23 multiplied by 2. 3 atoms per molecule so as the original respondent stated there are 4 mole of Hydrogen atoms and 2 mole of Oxygen atoms in 2 mole of water molecules. That number, hold on to your hat, is 3.61328202 X 10^24 or 3,613,282,020,000,000,000,000,000 and I believe that is Three Septillion Six Hundred Thirteen Sextillion Two Hundred Eighty Two Pentillion Twenty Quadrillion. Which is alot, alot, alot, alot, lot, lot, lot, lot, lot!

What's the reaction between coke and salt?

User Avatar
I am not too sure about what you are asking. In chemistry, coke is simply carbon. Salt is any ionic compound formed by a neutralization reaction between an acid an a base. Generally, all salts do not react with carbon, no matter what form the salt is in (i.e. solid or aqueous). * Added by Zaminlove: I think that coke stands here for Coca Cola! It frothes up. * Another note: Yes, in US slang coke is Coca-Cola. And sodium chloride (and other substances) can catalyze the violent releasing of carbon dioxide from this coke, forming a column as a little geyser. For a detailed discussion see the link below.

Why is tin IV selenide SnSe2?

User Avatar
Tin(IV) has a positive four charge. Selenide usually forms a 2- ion. Ionic compounds need a neutral, balanced charge. With the above information, the rest is pretty much just math. Tin - Sn(+4) Selenide - Se(-2) So you need two of Se to balance the +4 with a -4. = SnSe2 The answer above is OK, however if you are familiar with the idea of oxidation states SnIV is tin in its 4th oxidation state. Selenium has a common oxidation stae of -2 and once again you can do the math. The bonding in SnSe2 is not ionic so using oxidation states is preferable.
