In the reaction mg 2hcl right arrow. mgcl2 h2 which element’s oxidation number does not change? cl mg h
netineya [11]

The correct answer is Cl.

Chlorine is a substance that's employed in industry and is present in a number of household goods. There are times when chlorine takes the form of toxic gas. Chlorine gas can be converted into a liquid by applying pressure and cooling so that it can be transported and stored. The term "oxidation number" refers to the number of electrons that an element's atom either loses or gains during the production of a compound. The charge that an atom seems to have when forming ionic connections with other heteroatoms is used to define an atom's oxidation number. Even if it develops a covalent bond, an atom with a higher electronegativity is given a negative oxidation state.

Grassland has a somewhat high temperature and average humidity enough to keep it green and grassy hence grasslands.

A wetland has a lot of water but low temperatures. Still, humidity is water so wetlands aren't it.
