Hydrogen: 2.00 ÷ 18.0 = 11.1%
Oxygen: 16.0 ÷ 18.0 = 88.9%
H2O contains 11.1% hydrogen and 88.9% oxygen
How is cooking similar to an experiment?
Just like a scientific experiment, cooking involves performing different functions on various ingredients that may be combined by mixing or chemically changing them into a new substance, using heat or some other catalyst. You have to get the amounts of each item right and you have to perform actions on those items in specific, repeatable ways, for the right amount of time. Very scientific, indeed!
20 percent left in a 100 pound propane tank is how many pounds?
20 percent of 100 pounds is 20 pounds. Therefore, if there is 20 percent left in a 100-pound propane tank, there are 20 pounds of propane remaining in the tank.
The process is called cracking, where high-molecular-weight hydrocarbons are broken down into smaller molecules. This can be done through thermal cracking (heating the hydrocarbons at high temperatures) or catalytic cracking (using a catalyst to speed up the reaction). The smaller hydrocarbons produced, such as gasoline and diesel, are important components of fuels.
What polymer derived from acetylene gas is called polychloroprene?
Polychloroprene is a synthetic rubber polymer derived from acetylene gas. It is better known by its trade name "Neoprene" and is widely used in various applications due to its excellent resistance to oil, heat, and weathering.
How does one neutralize methane in a lift station?
It all depends on what you mean by neutralize. Methane is a gas given off when organic material decays with little of no oxygen present. It is an odorless flamable gas. Usually there are other gases formed at the same time (such as hydrogen sulfide) that has a bad smell. There is not much that can be done about it except vent it to the atomosphere to prevent explosions. In large treatment plants, it is collected and burned as a fuel but this is not practical in a lift station.
Anaerobic decay can be stopped by adding an oxidident such as chlorine. This kills the bacteria and stops decay until the chlorine combines into stable compounds. Then the decay will resume.
One way to prevent or minimize methane in the design process, is to dispatch the wastewater as quickly as possible. The longer it sits, in the tank, the more the decay and the more methane is produced. This can be accomplished by pumping more often. States usually regulate the storage and pumping requirements which may interfere with a good solution. They are less concerned with odor than they are making the station big enough to handle large periodic loads... which may increase the time the wastwater sits during times of low flows.
One simple improvement might be to pump the tank down at night (when the flow drops off) whether it has reached the "pumps on " level or not.. so it doesn't sit all night while the population is sleeping.
What is the cost of propane for heating per liter in Ontario Canada?
The cost of propane for heating in Ontario, Canada can vary depending on factors such as the supplier, current market prices, and delivery fees. On average, it can range from $0.60 to $0.90 per liter. It is recommended to contact local propane suppliers for specific pricing information.
Yes, methane is odorless in its pure form. However, in natural gas used for household purposes, an odorant called mercaptan is added to give it a distinctive smell, often described as similar to rotten eggs, for safety reasons.
To determine the evacuation distance for a tank, you need to consider the tank's size, contents, and local regulations. In this case, with a tank size of 4.1 x 21.3 feet and a mass of 7055 lbs of propane, proper safety measures should be followed. Evacuation distance would typically be determined by local fire codes and safety regulations to ensure a safe distance in case of a leak or emergency. It is advisable to consult with local authorities or a safety professional for specific guidelines.
What is the difference between green gas and propane for airsoft?
Green gas is just propane with some oil added to it. You can get a propane adaptor and use propane. Edit: The oil in question is silicone oil. Also, propane often has an additive called ethyl mercaptan, which causes its pungent smell. Green gas generally has a less strong smell, or none.
If your propane tank was at 40 percent and the propane company filled it to 80 percent, they added 40 percent of the tank's capacity in propane. The amount of gallons added would depend on the size of the tank, as propane tanks come in various sizes.
What is hydrocarbon and its function?
A hydrocarbon is a molecule composed of hydrogen and carbon atoms. Its primary function is as a source of energy, as hydrocarbons can be burned to release heat, powering engines and generating electricity. Hydrocarbons are also essential building blocks for various products like plastics, solvents, and fuels.
Do you need to change the pilot orifice when changing from propane to natural gas?
Yes, you typically need to change the pilot orifice when switching from propane to natural gas. Propane orifices are smaller than natural gas orifices due to the different properties of the gases. Using the incorrect orifice can lead to improper fuel combustion and potential safety hazards. Be sure to consult the manufacturer's guidelines or a professional for proper installation.
To find the minimum evacuation distance, we need to calculate the volume of the tank, the mass of propane it can hold, and then divide the mass by the volume to get the density. With this density, we can determine the evacuation distance based on the desired safety distance per pound of propane. The specific calculation will depend on the specified safety guidelines for propane storage and evacuation distances.
Why do hydrocarbons with longer chains have higher densities?
Hydrocarbons with longer chains have higher densities because they have more atoms per unit volume, resulting in a more tightly packed molecular structure. This increased mass per unit volume leads to higher density compared to hydrocarbons with shorter chains.
Can one hydrogen atom bond with one carbon?
Yes, but more is needed. According to the octect rule, atoms want to fill their outer most valence shell with the maximum amount of electrons. When this is applied to carbon, carbon wants to have 8 electrons in its outer most valence shell. As a neutral atoms, carbon has 4 electrons in its outer most valence shell. Hydrogen has only one electron, so it only has one elctron to give. This means carbon attacthed to one hydrogen atom has 5 electrons in its outer most valence shell. Carbon will still want to bond to more atoms in order to have 8 electrons in its more outer valence shell.
Is petroluem jelly water based?
Petroleum jelly, also known as petrolatum, is not water-based. It is a semi-solid mixture of hydrocarbons derived from petroleum, which is a non-polar substance. Water-based products contain water as the main ingredient, whereas petroleum jelly is oil-based and does not contain any water.
Yes, a crystal is a solid material that has a highly ordered and repeating atomic structure. Crystals are formed when atoms or molecules arrange themselves in a regular pattern, giving them their unique shape and properties.
How do you convert 1 chloropropane to 2 chloro propane with structure?
React with alcoholic KOH (dehydrohalogenation) to give 1-propene, followed by treatment with HCl (electrophilic addition).
The wick may not be burning due to insufficient air supply. The flame needs oxygen to burn, and if the wick is not getting enough air, it may not ignite. Try adjusting the position of the wick or increasing ventilation to allow for better combustion.
What is liquid petroleum hydrocarbon?
Liquid petroleum hydrocarbon refers to a compound made up of carbon and hydrogen atoms derived from petroleum. These hydrocarbons are in liquid form at room temperature and can include various compounds such as gasoline, diesel, and kerosene. They are commonly used as fuels for transportation and heating.
Is methanol a saturated or unsaturated hydrocarbon?
No, because hydrocarbons consist of only hydrogens and carbons. The suffix "-amine" means that there is a nitrogen somewhere in the formula.
What type of reaction is exhibited by alkenes?
Alkynes undergo many addition reactions such as: catalytic hydrogenation, addition by electrophilic reagents, hydration with tautomerism, hydroboration reactions, and oxidations. They also undergo nucleophilic addition reactions & reduction. Finally alkynes are the strongest bronsted acids made from only hydrocarbons.
What is the difference between Gypsum and Anhydrite?
Anhydrite is formed from dehydrated gypsum or to make it easier to understand when water is added to anhydrite it becomes gypsum as we can see from their chemical formulas
[Anhydrite (CaSO4) and Gypsum (CaSO4-2H2O)].
How do you set up a residential propane tank in Washington state?
