Hydrocarbons

Because they are better for the environment (biodegradable - will rot down and create fertile soil) and because crude oil was not needed to develop the material, they used cornstarch, so it is renewable.

PLA is used in carrier bags, sandwich containers, plastic cups and plastic cutlery.

hope this help :)

Propane heats ammonia and water in solution in a generator, the ammonia is separated from the water in a separator. The water is sent to an absorber to re-absorb "used" ammonia. The ammonia rises to a condenser where it cools and condenses. It then is mixed with hydrogen in the "evaporator" coil inside the refrigerator where it chemically combines with the hydrogen, evaporates and cools, allowing it to absorb heat from the refrigerator. This mixture then passes to the absorber where the ammonia is absorbed by the water and the hydrogen is released for reuse. The ammonia water mix is then returned to the generator to repeat the cycle. Without heat added at the generator the cycle will not have any "motive" force, and stops until heat is reapplied.

**The chemical reaction of ammonia 2(NH3) + H2 ---> 2(NH4) converts liquid ammonia to gaseous ammonia, and creates the cooling effect.

The absorption of this gaseous ammonia by water releases hydrogen, for this reaction.

I don't know if anyone has ever measured it, but they have with cows. I always used the 10% rule. Most goats weigh 10% of the equivlent dairy cow breed, and give 10% of the milk. I would GUESS, based on that, 10% of the methane volume would be a close approximaiion.

Actually, all gases do this to some extent. This is sometimes called the greenhouse effect, although the physics driving it work nothing like a greenhouse. Without the atmosphere's greenhouse effect, this would be a cold, dead planet with an average temperature well below zero (F). The Earth gets heat from solar radiation, but like all objects, it will re-emit some of this radiation back into space, losing its potential heating effect (what proportion is lost to re-emission varies from substance to substance). Now, the gases in the atmosphere have this same property, so it absorbs some of the energy Earth emits and does the same thing, sending some of Earth's emitted radiation right back to the Earth, which is then warmed because it gets back some of the energy it emits. But as I wrote, some substances are better at doing this than others, and the problem is that the gases you mention are very good at it. If their concentration in tbe atmosphere increases, then the air as a whole also gets better at it, increasing the greenhouse warming effect.

Go to your local hardware store and ask for an orifice to convert your stove from natural gas to propane. I am sure a salesperson will tell you how to install it if it doesn't come in a package with instructions.

For every mole of propane (C3H8) that reacts, 4 moles of water (H2O) are produced. Since 1 mole of gas occupies about 22.4 L at STP, if 4.50 L of propane reacts, you would need to convert the volume of propane to moles using the ideal gas law to determine the moles of water produced.

Yes as Propane is in the homologous series and propane is the very simplest of them so it only has one covalent bond.

eg:

H-H

H-C-C-H

H H

Easily explosive with wide range of air mixtures.

The difference between an alkane and an alkene is that:

Alkanes have only single bonds between carbon atoms and

are said to be saturated: when put in bromine water, the bromine water stays orange -

formula: CnH2n+2;

Alkenes: have one or more double bond(s) between carbon atoms and are unsaturated:

when put in bromine water, the bromine water turns clear - formula: CnH2n.

There is no chemical with the formula N4HO. It appears to be a non-existent or incorrect formula.

Pyruvic Acid

Prior to 1989, trichlorofluoromethane (CFC-11) and dichlorodifluoromethane (CFC-12) were the most used chemical compounds in aerosol-spray propellants. Their use was discontinued under the Montreal Protocol.

No. A hydrocarbon is a molecule that is made up of just hydrogen and carbon, as the name implies. Diamond is made of a "diamond lattice" of carbon atoms bonded together covalently, but contains no hydrogen. A common example of a hydrocarbon would be propane or methane.

The viscous material in Harpic toilet cleaner is typically a mixture of thickening agents, such as hydroxyethyl cellulose or xanthan gum, which help the cleaner cling to the toilet bowl surface for better cleaning action.

Rice paddies are a significant source of methane emissions in agriculture, producing around 100 million tonnes of methane per year globally. Methane is produced in rice paddies through anaerobic decomposition of organic matter in the flooded soil. The amount of methane produced can vary depending on factors such as soil conditions, water management practices, and rice varieties.

The time it takes for a person to become unconscious from methane gas exposure varies depending on the concentration of the gas in the air, the person's level of activity, and their overall health. In high concentrations, exposure to methane gas can cause rapid onset of symptoms like dizziness, nausea, and unconsciousness in a matter of minutes. It is important to immediately evacuate the area and seek medical attention if methane gas exposure is suspected.

1. Both ammonia and methane are gases at room temperature.
2. They are both naturally occurring compounds found in the environment.
3. Ammonia and methane form flammable mixtures with air.
4. Both compounds are used as sources of fuel and are important in various industrial processes.

Tankless water heaters can be powered by electricity or propane. Electric tankless water heaters are more common, but propane tankless water heaters are popular in regions where natural gas is not available. Both types offer energy efficiency and the convenience of on-demand hot water.

The sun does not burn in the conventional sense, it is a fusion bomb confined by its own gravity. At the core of the sun, hydrogen plasma fuses to form the element helium, a and this fusion releases the energy which makes the sun hot.

hydrogen, helium

Methanol has the highest boiling point among methane, chloromethane, and methanol. This is because methanol has stronger intermolecular forces (hydrogen bonding) compared to methane (only dispersion forces) and chloromethane (dipole-dipole forces).

Coal is considered a hydrocarbon because it is primarily composed of carbon and hydrogen atoms. When coal is burned, it undergoes combustion with oxygen, releasing energy in the form of heat and producing carbon dioxide and water vapor as byproducts. This combustion process is characteristic of hydrocarbons.

No, you should never use butane gas in a diesel car as it can cause serious damage to the engine. Diesel engines require diesel fuel for proper combustion and performance. Using a different type of fuel, like butane gas, can lead to engine misfires, damage to the fuel system, and potentially dangerous situations.

Yes, methane hydrates form in seafloor sediments in cold, high-pressure environments. While they contain significant amounts of methane, extracting and converting them into energy sources remains technically challenging and costly compared to conventional fossil fuels. Further research is needed to assess the environmental impacts and feasibility of large-scale methane hydrate extraction.

THe chemical formula (not molecular sign) for propane is C3H8.
