Given the chemical reaction fe3o4 + h2 ⟶ fe + h2o, identify the coefficient of h2o in the balanced equation. 1 2 6 4

The coefficient of in the balanced chemical equation is 4.

Explanation:

Every balanced chemical equation follows Law of conservation of mass.

This law states that mass can neither be created nor be destroyed, but it can only be transformed from one form to another form. This also means that the total number of individual atoms on the reactant side will be equal to the total number of individual atoms on the product side.

For the given balanced chemical equation:

The coefficient of in the balanced chemical equation is 4.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
