An unbalanced chemical equation is shown: h2o2 → 2h2o + o2 which of the following statements explains why the equation is not balanced? a two h2o2 molecules should decompose to form the given products. b four h2o2 molecules should decompose to form the given products. c two h2o2 molecules should undergo a synthesis reaction to form the given products. d four h2o2 molecules should undergo a synthesis reaction to form the given products.

A  - Two H2O2 molecules should decompose to form the given products.

Explanation:

Did the test and got it right

- a) Two molecules should decompose to form the given products.

Explanations:- The given equation is:

A balanced equation must have equal number of atoms of each element. If we look at the given reaction then hydrogen peroxide is decomposing to give water and oxygen gas. Also, if we look at the H and O then left side has two H and two O where as the right side has four H and four O.

Neither H nor O is balanced. Left side has exactly half H and O as compared to the right side and so to balance this we need to multiply hydrogen peroxide by two.

The balanced equation will be:

Hence, choice a is correct. "Two molecules should decompose to form the given products."

ill try to . no promises tho.

explanation:

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.
