The chemical compound seen here is called methane. carbon and hydrogen are chemically combined using chemical bonds in which electrons are

Explanation:

A covalent bond is defined as the bond which is formed by sharing of electrons.

For example, atomic number of carbon is 6 and its electronic distribution is 2, 4. Whereas atomic number of hydrogen is 1.

Hence, in order to complete their octet a carbon atom needs 4 more electrons whereas a hydrogen atom needs one more electron.

Therefore, both carbon and hydrogen atom will combine together and result into the formation of that is, methane.

Therefore, we can conclude that the chemical compound seen here is called methane. Carbon and hydrogen are chemically combined using covalent chemical bonds in which electrons are shared.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
