Elements and Compounds

Parent Category: Chemistry
Questions about the properties and characteristics of elements as observed in nature and in compounds. Chemical formulas are also converted to and from symbols in covalent or ionic bonds. All the questions you want to ask about the elements and the compounds they form.
Yes, if you add plenty of water. When boiling ham or bacon we oftenput it in water, bring it to the boil, and then discard the first water and replace it for the restof the cooking. This gets rid of some of the salt. However, if youhave a liquid (e.g. a soup or gravy), boiling it will onlyevaporate...
Microbial contamination (such as mold and yeast) can enter after the bottle is opened. Magnesium citrate formulas give microbes an ideal environment to grow.
Oxidation. At high temperature magnesium ignites - and that iscalled combustion.
Oxygen, sulfur and the elements of group 17.
You can boil water and other liquids out of canned meat but thesalt will stay behind. In fact any solids dissolved in a liquidwill be left behind since when the water boils away, the dissolvedsubstance will precipitate out of solution and will be left behind.Rinsing the canned meat and pouring out...
It is suggested you do this to avoid microbial contamination as itattracts moisture from the air. Magnesium Citrate does notdecompose quickly. Under the proper conditions it should still befine to continue using the oral solution after 24 hours. Considerrefrigeration, tightly sealing the bottle, or...
The neutron has about the same mass as the proton, each hasa mass a tiny amount greater than 1 AMU (atomic mass unit). Theneutron is the smallest bit more massive. The electron has a mass of just a bit over 5/10,000ths of an AMU.Extremely less massive in comparison, isn't it!
No. There is a single covalent bond between the two atoms of achlorine molecule.
The ionic charges of group 1 and 2 metals are +1 and +2respectively. Group 15 & 16 the simple mono-atomic ions are -3and -2. Group 17 ions are -1. This can be explained by thefollowing elemnts in groups 1 and 2 lose 1 or 2electrons respectively to achieve a noble gas configuration whereasgroups 15...
Generally the electrons are transfered from the metal elements tothe nonmetalic elements so that both form stable electronconfigurations. For example, in sodium chloride one sodium atomloses an electron so that it has the stable electron configurationof Neon and chlorine gains one electron so that...
The electrical resistance between subatomic particles is farreaching from the atomic nucleus and electron cloud. Electrons arealso moving very fast. The probability cloud that determines wherethe electrons could be, the orbitals and the nucleus itself, arestill not solid objects. Keep in mind under...
The electromagnetic and strong nuclear forces are very powerful andrepulsive at close ranges. Put two atomic nuclei near each otherand they will push away from each other. Similarly if you put twonegatively charged particles near each other they will also repelat very close distances.
Nitrogen would extinguish the flame. Unlike most burning fuels,magnesium will continue to burn in carbon dioxide because its flameis hot enough to decompose carbon dioxide to carbon and oxygen.
group1: +1 group2: +2 group15: -3 group16: -2 group17: -1
The uses of aluminum are varied and diverse. Today it is usedin commerce, transportation and other industries. Some of itsapplications are well known, while others are not so obvious. Apartfrom consumer products, the metallic element is also used in glasscreation. . Use in Households This metallic...
Metals useually have few valence electrons and they loose electronsfrom their outermost shell thus, forming an ion with positivecharge (cations). This is because it is easy for metals to looseelectron and attain stable or octet configuration similar to raregases. Hence to attain stability metals...
soap, its what makes it slippery
Yes, Sodium sulfate is categorized as one ofmany salts. . It is the sodium salt of sulfuric acid. . When anhydrous, it is a white crystalline solid of formulaNa 2 SO 4 . But the "salt" on your table that you sprinkle on your fried eggsis not sodium sulfate. It's a different sodium salt ......
Amla, Guava, Lemon, Orange etc..☺
If it is heated to 160 degrees Celsius it yo momma melt anddecompose into acetone vapor and calcium carbonate.ngn
In an ionic compound the charges must balance out to zero. Since the nitride ion has a 3- charge and sodium forms a 1+ ion so in sodium nitride there are three sodium ions (Na + ) fore every one nitride ion (N 3- ).
No, it is a non metallic complex ion but it forms salts (Ioniccompounds) just like metallic ions.
Yes, it gradually corrodes, though in the right environment it canlast a long time.
Utah: they get salt from salt mines where the salt lake is . Salt can come from a number of sources. It can be processed fromthe sea water with machines, be collected when the water in seawater has evaporated, or be mined out of salt mines.
Calcium oxide - CaO Ca: 20 electrons Oxygen: 8 electrons Total: 28
An octet electron arrangement is where an atom has 8 valence electrons. It's very stable and unreactive. Some metal atoms tend to donate its electrons and the electrons accepted by non-metal atom. This is called ionic bonding. Some non-metal electron share electron among themselves to achieve...
Sodium chloride (NaCl) is a unique substance, a compound formed by a chemical bond. A mixture involve the existence of min. two different substances.
Radium is a decay product of uranium and is constantly beingproduced. U-238 has a half-life of about 4.5 billion years, sothere's still quite a bit left of the original amount on Earth.
Many substances will cause water to lather when shaken. However, Iwonder if you mean how can soap be made? The ingredients are fatsand alkali, and there is no organic alternative to the alkali.
its the shape of an orbital
The molecules of water are held together by hydrogen bonding between molecules. These are electrostatic bonds (attraction forces between opposite charges) that hydrogen makes with the oxygen of neighbouring molecules. Hydrogen, when bonded to oxygen to form water molecules, is slightly positive...
Principle of Natural Sciences
They are different chemicals and one is a very strong acid and theother is a very strong base, respectively.
Cx Hy + O2 ---> CO2 + H2O
It depends what compound it is in. In water it is covalent. Intrichloracetic acid it is ionic.
Protons and neutrons are called hadrons. A hadron contains threequarks. Quarks come in 6 flavors (types). These types are up, down,top, bottom, strange, and charmed. (The names are completelyarbitrary.) A proton contains two up quarks and one down quarkwhile a neutron contains one up quark and two...
If you're asking about whether or not there would be a reaction,then probably not. You have two compounds with the same anion, soyou will just have a big aqueous solution of chloride ions, plussome hydrogen and ammonium ions.
dT = (i)(Kf)(m) is the equation that can be used to model thefreezing point depression. dT represents the change change in temperature. i represents the amount of ions formed from the dissolution of thesolute. Kf represents the constant of the freezing point depression ofwater. m is the molality of...
Marble CaCO 3 can not be melted it becomes decomposed on heating, in to CaO and CO 2 .
marble is a form of calcium carbonate and contains imprities thatgive it its aesthetcally pleasing appearance. In nature marble isformed by the melting of sedimentary calcium carbonate under highpressure and high temperature conditions. Melting calcium carbonateis very difficult under normal...
The bubbles you see are oxygen gas, produced by the decompositionof the hydrogen peroxide.
They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by twoatoms, and bind the atoms in a fixed orientation. Relatively highenergies are required to break them (50 - 200 kcal/mol). Whethertwo atoms can form a covalent bond depends upon their...
Yes. But this occurs because salt is soluble in water, in which thecoloring is dissolved. The color is retained by the salt crystalswhen they dry.
The sodium chloride crystal arrangement is a cubic crystal lattice (a regular, repeating pattern) or a "salt crystal". Every chlorine ion (negatively charged, as they gain an electron in this case) is surrounded by 6 sodium ions (positively charged, as they lose an electron in this case), as...
93% sulfuric acid is Virgin sulfuric acid. It is a good drainopener.
Neither. Silica is a compound of two elements: silicon and oxygen. Oxygen is a nonmetal, silicon is a metalloid.
Most atoms are electrically balanced because they have the same number of protons, which have a charge of +1, and electrons, which have a charge of -1. However electrons can be lost or gained. When they are, the atom has a different number of protons to electrons so it becomes charged. Example. An...
Ionic compounds intra molecular forces deal with charges which dictates their attractions. Example Na+ and Cl- balance out to form NaCl ( include states in a real equation). While their inter molecular forces, which are the forces between molecules causes them to be set up in a crystal lattice...
No. sulfur does not react with water.
Zinc is a solid, brittle and crystalline at room temperature, butit becomes ductile and malleable when heated between 110°C and150°C. It has a melting point of 692.68 K (419.53ºC) and a boilingpoint of 1180 K (907ºC) (K=Kelvin)
It is silver in colour. It has a low melting point. It is resistantto corrosion, despite its reactivity.
I believe it is 1997
No. A metal plus an acid gives a salt and hydrogen. e.g. sodium +hydrochloric acid --> sodium chloride (salt) +hydrogen. 2Na +2HCl --> 2NaCl + H2
Because it's a base, and will react with your dead skin,effectively exfoliating it.
5869 degrees Kelvin. Rhenium would be the last element to go, withtungsten right before at 5555 degrees Celsius.
I'm not sure why there would be a biography on an ionic bond but,ionic bonds are when atoms bond by transferring electrons.
indicate the total number of p electrons in N(z=7) s electronsinSi(z=14) 3d electronsin S(z=16)
The products formed are magnesium chloride and water.
electrons and neutrons. When electron # changes it creates an ion.When neutrons # changes it is called an isotope.
As a soluble substance we wouldn't expect to find potassium acetatein nature.
At normal pressure, the alkanes pentane (C5H12) through decane(C10H22) are liquids. Alkanes are organic compounds consisting of asingle carbon chain of single covalently bonded carbon atomssurrounded by hydrogen atoms.
I am sorry idk the asnwer it in my book for homework but if u have a bae I can answer any question for that
We know helium , neon , argon , krypton , xenon and radon as the inert or noble gases. You probably don't need examples since there are only six of these elements. Why not just list them all?
You would just call it liquid magnesium, or molten magnesium whichmeans the same thing.
Molten magnesium is still metallic magnesium. It is in liquid state.
Helium has a full outer shell of electrons, meaning it is stable in its elemental form and does not form chemical bonds or participate in chemical reactions such as combustion.
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
NO, it's an trivalent anion ( negative charge species)
titanium does not exist, therefore, JazzyB wins.
you have to know the conentrations fo at least two of yourcompaunds or it is not posible to answere this.
The two main components of acid rain are sulfur dioxide (SO2) and nitrogen oxides (NOx). Sulfur dioxide is a colorless gas released by combusting fossilfuels that contain sulfur. Sulfur dioxide reacts with the moisture in the atmosphere to formsulfur trioxide. Sulfur trioxide then joins with...
no, hydrogen can also change your voice because it is also light,but there are compounds such as sulfur hexafluoride which deepensyour voice.
Because two atomic centres can only create a linear molecule.
There are several atoms that do not take part in chemical reactions. They called noble gases. They are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Kr), and Radon (Rn).
Ya, cuz 1 time in Star Trek they had transparent aluminum. For some whales and junk and its totally based on actual events that will take place in the future probably.
