Hydrocarbons

Styrene is not considered an alkene because it contains a benzene ring in its structure in addition to the ethenyl functional group. Styrene is categorized as a vinyl aromatic compound.

The bond angles in ethene (C2H4) are approximately 120 degrees. This is due to the sp2 hybridization of the carbon atoms in ethene, creating a trigonal planar geometry. The H-C-H bond angles are all equal in this molecule.

If you want to know how to make methane gas out of rabbit manure, you have to mix the manure with leaves, food and dirt. Then you have to put everything in an old plastic bag so everything will decompose if you leave it outside for a month or less. Once you've completed that you will go back outside and you'll see gases rising from that manure.

Because in wurtz synthesis you have two alkane molecules which react with each other, for instance two iodomethane groups and sodium. You would get sodium iodide and two groups of methane, which equals ethane.

To determine the amount of butane that combusts, we need to use the enthalpy of combustion for butane, which is -2877 kJ/mol. Since the heat produced is 1550 kJ, we can set up a proportion to find the amount of butane consumed. By dividing the heat produced by the enthalpy of combustion per mole, we will get the number of moles of butane consumed. From there, you can convert moles to grams using the molar mass of butane (58.12 g/mol).

The molar mass of methane (CH4) is 16 g/mol. Therefore, four moles of methane would have a mass of 64 grams.

an Alkene as it contains a double bond and is unsaturated

An alkyl group is a portion of an alkane molecule that has a hydrogen atom removed. This removal of a hydrogen atom leads to the formation of a free radical, giving the alkyl group its characteristic reactivity. Alkyl groups are used as building blocks in organic chemistry and can be attached to other functional groups to create a wide variety of organic compounds.

1 carbon - methane

2 carbons - ethane

3 - propane

4 - butane

5 - pentane

6 - hexane

7 - heptane

8 - octane

The main function of use of methane gas is that it is the main constituent of the natural gas which is used as a fuel in automobiles and for domestic uses as well. It is very clean and also provides a high calorific value.

Propane is used as a propellant to expel the product out of the can. It's a gas. When released from the can, it expands quickly making the liquid in the can turn to foam. So there's nothing to leave a residue in your hair.

there are 8 hydrogen atoms present in propane.

There is 8 hydrogen atoms in propane, Each carbon has a valency of 4, 4 bonds with other atoms. Hydrogen has valency of 1. the general formula for alkanes is CnH2n +2 (n means number of that atom.) so to find how many hydrogens there with, say, 50 carbons you would do CnH2n + 2= C50H102. :)

No, and that's exactly the reason for making it larger ... in order to be able to

carry more propane around at the same pressure as the small tank, or maybe

even somewhat less pressure.

Alkenes are used to make polymers through a process called polymerization, where the double bond in the alkene is used to form the backbone of the polymer chain. By initiating polymerization reactions with catalysts, heat, or light, alkenes can be linked together to form long chains of repeating units, creating various types of synthetic polymers. Examples include polyethylene, polypropylene, and polystyrene.

Normally, when substance burns, the molecules undergo a rapid oxidation, which excites the molecules greatly. The heat that is input into the substance, and the oxidation process, causes the molecules to move around very quickly. As the molecules return to their lower energy resting state, they shed the excess energy in the form of heat. When the goal is to char, instead of burn, the molecules are exposed to the same heat as for burning, but they are denied oxygen. Since the materials do not have access to oxygen, they do not burn (rapidly oxidize). All of the molecules still get excited, and move and bump into each other, but the fuel is not consumed, as that requires oxygen. Once the molecules of the substance get hot enough, any molecules of water or other liquids change state to a gas and are driven out of the substance being heated, because of the expansion of the gas. Charring is most commonly used to dry wood completely, without using up the wood's potential energy as fuel.

Sodium propanoate (or propionate) when heated with soda lime ethane gas is produced.

no thats completely stupid.

butane reacts with oxygen to produce carbon dioxide and water

Yes, bananas do produce methane gas as they ripen. As the fruit breaks down, it emits small amounts of methane due to the fermentation of sugars in its tissues. However, the amount of methane released from bananas is relatively low compared to other sources of methane emissions.

That would all depend on the size of house, cost of propane etc. Propane would definitely be cheaper than electric heat.

A 3,500 square foot home in Minnesota using radiant in-floor heat (during winter of 2010/2011) cost between $750 and $850 per month for propane (about 375 gallons per month x $2.26 per gallon).

The official densities at room temperature for the following substances are:

• Ethanol: 0.789 g/mL
• Chloroform: 1.48 g/mL
• Heptane: 0.684 g/mL
• Diethyl ether: 0.715 g/mL.

Carbon dioxide is the gas that is the product of combustion of propane.

Converting a natural gas heater to propane gas usually involves changing the orifice size and adjusting the gas pressure. It's important to consult the manufacturer's instructions or hire a professional to ensure the conversion is done safely and properly. Using the wrong type of gas can be dangerous and damage the heater.

Chemical formula of propane is C3H8.
When propane combines with oxygen in the presence of heat source, we get an exothermic reaction.
C3H8 + O2 --> Exothermic reaction (burns with bluish flame along with carbon dioxide, water and particulate matter).
