What bacteria can utilize methane as their source of energy and do not need oxygen for their survival?

Methanogenic archaea are the bacteria that can utilize methane as their source of energy and do not require oxygen for survival. These bacteria produce methane as a byproduct of their metabolism. They play a crucial role in anaerobic environments such as wetlands and the digestive systems of animals.

Who found alkenes?

Alkenes were first discovered by the French chemist Théophile-Jules Pelouze in 1834. He isolated the first alkene, ethylene, by heating ethanol with sulfuric acid.

What accounts for the differences between alkynes alkenes and alkanes?

Alkane: -ane. C-C interaction has single bond

Alkene: -ene. C-C interaction has double bond

Alkyne: -yne. C-C interaction has triple bond

Least reactive alkanes are saturated hydrocarbons, while alkene and alkyne not. Alkanes undergo susbstitution reaction while others under go addition reactions rather.

Alkanes rule is CnH2n+2 while alkene CnH2n and alkyne CnH2n-2.

Why use a no vent propane fireplace?

A no-vent propane fireplace is beneficial because it doesn't require a chimney or venting system, making installation easier and more flexible in terms of placement. It also provides efficient heat output and can be more cost-effective compared to traditional vented fireplaces. Additionally, it avoids the potential for air leakage and heat loss associated with vented systems.

Is C2H6 a hydrocarbon?

Yes, C2H6 is a hydrocarbon. It is specifically a saturated hydrocarbon known as ethane, which is composed of two carbon atoms and six hydrogen atoms.

How many methane molecules of Ch4 have a mass equal to 3.20 grams?

One mole is equal to 6.022 x 1023 of anything. In this case, we are looking for molecules. So 1 mole=6.022 x 1023 molecules. We have 2.3 moles, so we want to know how many molecules are there.

2.3 mol CH4 x 6.022x1023 molecules CH4 / mol CH4 = 1.38x1024 molecules of CH4

What is the formula of fitkiri?

There is no specific formula for catching a "fitkiri" as it refers to a Nepali tradition where one person closes their eyes and tries to catch another person by listening to their sound. It is more of a game or folk activity rather than a formulaic process.

Do trees take in methane?

Yes, trees can take in methane from the atmosphere, mainly through their leaf surfaces. Microorganisms living on the trees' surface and within the soil around them can also help break down methane into carbon dioxide and water. This process can contribute to reducing methane levels in the atmosphere.

What are the element in butane?

Carbon & hydrogen are the two types of elments of the present in butane.

How many elements are left to discover?

It is difficult to determine an exact number of elements left to discover as new elements are constantly being synthesized in laboratories. However, the periodic table is thought to be mostly complete, with the discovery of new elements becoming increasingly rare due to their short lifespans and high reactivity.

How many distinct alkene products are possible when a alkyl halide undergoes E2 elimination?

Two distinct alkene products are possible when an alkyl halide undergoes E2 elimination. One product results from the removal of a beta hydrogen on one side of the molecule, while the other product results from the removal of a beta hydrogen on the opposite side.

Are cigarettes made with butane?

No, cigarettes are not made with butane. Cigarettes are typically made from tobacco leaves that are treated and processed, then rolled into a cylindrical shape. Butane is a highly flammable gas that is not used in the production of cigarettes.

What is the difference between Ethane and EP Mix?

Ethane is a simple hydrocarbon compound consisting of two carbon atoms and six hydrogen atoms. EP Mix, on the other hand, is a blend of ethane and propane in varying ratios, typically used as a refrigerant in air conditioning and refrigeration systems. EP Mix offers a different boiling point range compared to pure ethane, making it suitable for different applications.

What is hydrocarbon fire extinguisher?

A hydrocarbon fire extinguisher is a type of fire extinguisher specifically designed to combat fires fueled by flammable liquids such as gasoline, oils, and grease. These extinguishers contain agents like dry powder or foam that work by smothering the fire and cutting off the oxygen supply to extinguish the flames.

What is the importance of alkenes?

Alkenes are very important as:

1. They are used in the manufacture of polythene, Mustard gas(beta-beta dichloro ethyl sulphide)

2. Ethene, one of the alkenes, is used as a general anaesthetic and for artificial ripening of fruits.

3. Alkenes are used as a starting material for a large number of chemicals of industrial use such as glycols(antifreeze) , ethyl halide and ethyl alcohol.

Is there dark matter in earth?

Probably not. It is currently unknown exactly what dark matter is, but theories claim that it may comprise up to 90 percent of the mass in the universe. We can't even find life on the masses we can identify.

How much does nitro-methane fuel cost?

Nitro-methane fuel used in drag racing typically costs around $25-$35 per gallon, depending on the specific blend and manufacturer. The high cost is due to its specialized formulation and performance-enhancing properties.

Is helium found in methane?

No, helium and methane are separate gases. Helium is a noble gas that is primarily obtained from natural gas deposits, while methane is a hydrocarbon compound composed of carbon and hydrogen atoms. Helium is typically found in reservoirs separate from methane deposits.

What is the process in which large hydrocarbons are converted into smaller hydrocarbons which provide better fuel?

The process is called catalytic cracking. In this process, large hydrocarbon molecules are broken down into smaller molecules by exposing them to high temperatures and a catalyst. This results in the formation of lighter hydrocarbons that are more suitable for use as fuels.

Is methane released from the bottom of frozen lakes?

Yes, methane, a greenhouse gas 21 times more dangerous than carbon dioxide is generated whenever there is anaerobic decomposition (ie, without air) of organic material.

See the link below for a very quick video (13 secs) of about 10 grams of methane being burnt off a lake. Then multiply the 10 grams by just about any number of frozen lakes and tundra you can think of.

Is 2-methylpentane an alkane alkene or an alcohol?

Yes but you have to draw it as a 3 carbon ring structure (like a triangle) and the 1st carbon would have a CH3 and an OH.

Is it legal for a propane company to shut off heat and hot water in winter months?

First of all I haven't seen a propane gas company shut off any gas going to your home because most homes that run on propane have a tank and if you don't pay your bill then they won't come and fill it. Natural gas companies will shut off your gas and unless its your only way of heat and you have children living inside then they can not shut off your gas in cold winter months but you will still be charged for those months and might include interest so its best to always pay your gas bill and if you are struggling with money then try to keep your home heated to the minimum degrees you can comfortably like instead of your home temp being 74* f try keeping it around 68 or 69*f.

What colour is butane?

Butane is a colorless gas at room temperature and pressure.

Ethane a Alkene?

The carbon of the carbon-carbon double bond is sp2hybridized. Take CH3CH=CHCH3 as an example: the C of the double bond is sp2 hybridized, cause the C has 3 bond pairs (2 single bonds+1 double bond).

The hybridization state of a carbon can be calculated by spn-1 ,where n is the no. of bond pair , and n is stand for a single bond or a double bond or a lone pair electrons.

Take CH2=NH as an example: both the N and the C is sp2 hybridized cause for the N, it has one single bond, one double bond and a pair of lone pair electrons.

Is methane in the atmosphere?

Yes, methane is a greenhouse gas that occurs naturally in Earth's atmosphere. It is released through natural processes such as wetlands, as well as human activities like agriculture and fossil fuel production. Methane contributes to climate change by trapping heat in the atmosphere.
