Look at the unbalanced reaction below for the combustion of hydrogen gas. What needs to be done to balance the reaction? _ H2 + _O2 LaTeX: \longrightarrow⟶ _H2O

The given equation H2 + O2 => H2O is not balanced as the oxygen atom on the right side do not have the same number of atoms as of the left side.

In a balanced equation, the number of atoms on both sides are equal. So in this case, we are required to change the coefficient in front of H2O, in order to make oxygen atom balance, for that we need to change the coefficient of H2 as well.

It means to make the given equation balance we need to change the coefficient in front of H2 and H2O.

Balance equation: 2H2 + O2 => 2H2O

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
