Hydrocarbons

Synthetic oils are generally recommended for propane-powered emergency generators due to their ability to offer enhanced protection and performance in extreme operating conditions. Look for oils specifically formulated for use in high-temperature and high-stress applications to ensure optimal lubrication and engine longevity. It's important to consult the generator's manual and manufacturer recommendations to select the most suitable lubricating oil for your specific model.

When methane is burned, it reacts with oxygen in the air to produce carbon dioxide (CO2) and water (H2O). Since air also contains nitrogen, some of it can react with oxygen during combustion to form nitrogen oxides (NOx). Carbon dioxide and nitrogen oxides are byproducts of this combustion reaction.

1. The reaction of butane with oxygen is exothermic as it releases energy in the form of heat.
2. The melting of gold is an endothermic process as it absorbs heat energy to break intermolecular forces and change the state from solid to liquid.
3. The cooling of copper from 225°C to 65°C is an exothermic process as heat is released to the surroundings during the cooling.

No, sodium lauryl sulfate is not effective in extinguishing fires. In fact, it may even be flammable under certain conditions due to its chemical properties. Water, fire extinguishers, or fire retardants are more appropriate for putting out fires.

Both Uranus and Neptune have methane in their atmosphere which absorbs red light, allowing the blue hues to be reflected. Neptune is a lot more of a blue colour than Uranus, but Uranus has more methane in its atmosphere. Its though that other constituents in Neptune enrich its blue colour.

Methane burns away completely because it is a hydrocarbon that reacts with oxygen to form carbon dioxide and water. Metals, on the other hand, do not combust but rather oxidize when exposed to heat. The metal combines with oxygen to form metal oxides, which can appear as ash residue after the combustion process.

The principle energy level, represented by the symbol "n", is a measure of the average distance of an electron from the nucleus in an atom. Electrons with higher principle energy levels are farther from the nucleus and have higher energy levels. Each principle energy level can contain a specific maximum number of electrons based on the formula 2n^2.

Yes, (C3H8), 3 atoms of carbon and 8 atoms of hydrogen in each molecule of propane.

This data will be dted but here we go. I live in cookeville, tn winter 2007 saw cost/ gallon of propane at $3.09/gal. last time we filled was in feb i believe. a small drop this summer never came since propane is affected by crude prices. My guess based on increases etc for this year will be in excess of 3.50/gal, probably higher come early 2009.

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.
