The monomer of polyethylene is ethylene - H2C=CH2. {eth=2 carbons, ene=a CC double bond} Two methane - H2CH2 or H3CH - molecules condense to form ethane: H3C-CH3 + 2 H+. Another 2 H+ removal, or condensation, gives the -ene H2C=CH2.
Polymerization of the -enes is the next step. Via another condensation reaction, a poly-eth-ene appears thusly: H2C=CH|HC=CH|HC=CH|HC=CH|HC=CH|HC... & etcetera.

Can Acetylene Gas be used to form long chain hydrocarbons?
I have heard that Methane can be used to form longer chain hydrocarbon fuels, -why not the much higher energy bonded Acetylene?
What is the type of bond present between carbon and hydrogen in polyethylene?
In polyethylene, the bond between carbon and hydrogen is a covalent bond. This type of bond occurs when carbon and hydrogen share electrons, allowing them to achieve stable electron configurations. The carbon atoms in polyethylene form single covalent bonds with hydrogen atoms, resulting in a long chain-like structure characteristic of this polymer.
How many molecules of oxygen 2 are needed to react with which molecule of methane CH4?
To react completely with one molecule of methane (CH4), two molecules of oxygen (O2) are needed. This is because the balanced chemical equation for the combustion of methane is CH4 + 2O2 → CO2 + 2H2O. Each molecule of methane requires two molecules of oxygen to form carbon dioxide and water.
Is this reaction Endothermic The combustion of propane in oxygen to produce carbon dioxide and water vapor. And does methane or propane produce more energy combustion I just dont understand this?
All the combustion reactions I know of are exothermic because heat is released instead of absorbed. And propane gives more energy than methane cause it has more Cs and Hs to react with Oxygen, so one mole of propane will react more and form more product than one mole of methane and giving out more energy.

How do free radicals continue combustion?
Free radicals continue combustion by initiating chain reactions where they react with other molecules to form new radicals, which then react with more molecules, creating a self-sustaining cycle. This chain reaction produces heat and energy, contributing to the sustained combustion process.
How did polyethylene form?
It forms through addition polymerisation. The double bonds in ethene break to form a long continuous chain ( a polymer) which is polyethylene.
Does methane reacts with chlorine in dark?
Theotically, methane can't react with Cl2 in shade as UV light is required to initiate the substitution reaction. Only when there is Cl2 can the C-H bond be broken. However, alkene can react directly with Cl2 due to hydrohalogenation.

What is a single molecule that may react with similar molecules to form a chain?
"monomer"
What is an exmaple of a chemical reaction for exothermic?
Methane and oxygen react to form water and carbon dioxide and release considerable heat.
What is the source of energy used to react chlorine with methane?
The source of energy used to react chlorine with methane is typically heat, in the form of high temperatures. This helps to initiate the reaction between the two compounds and break the chemical bonds involved.
Why are carbides of beryllium and aluminium are called methanides?
Carbides of beryllium and aluminium are called methanides because they react with methane gas to form compounds. These carbides have the ability to react with methane in a way that is similar to other metal carbides, which is why they are classified as methanides.
How do flurocarbons affect the ozone layer?
They react with ozone. Decompose it and form a chain reaction.
Is methane an acid?
No, methane is not an acid. It is a simple hydrocarbon compound with the chemical formula CH4. Acids typically have a sour taste, can react with metals to form hydrogen gas, and can neutralize bases.
What is the products of hydrogen and carbon?
When hydrogen and carbon react, they can form various products depending on the conditions. However, under normal conditions, they typically react to form hydrocarbons such as methane (CH4) or hydrogen gas (H2) and carbon monoxide (CO).
How nitric acid react with methane?
Nitric acid does not react directly with methane under normal conditions. However, in the presence of a catalyst or under high-temperature conditions, methane can be oxidized by nitric acid to form carbon dioxide, nitrogen dioxide, and water. This reaction is not commonly used due to its complexity and the availability of more efficient methods for methane oxidation.
Can methane and bromine react without sunlight?
Methane and bromine cannot react without the presence of sunlight or U.V light because of lack of energy which is usually supplied by the U.V light to break the bromine molecules to free radicals for the reaction to occur.Hope my answer helped.ABUAD
