Answer 1

What type of reaction is shown below? 

2H2O2 → 2H2O + O2

A. synthesis
B. decomposition
C. combustiondecomposition

answer is B

Answer 2

Answer: Decomposition

Explanation:

1. Synthesis is a chemical reaction in which two or more reactants combine to combine to give a single product.

$2Mg+O_2\rightarrow 2MgO$

2. Decomposition reaction is a chemical reaction in which one reactant gives two or more than two products on absorption of energy.

$2H_2O_2\rightarrow 2H_2O+O_2$

3.. Combustion is a chemical reaction in which hydrocarbon burns in the the presence of oxygen to form carbon dioxide, water and energy.

$C_3H_8+5O_2\rightarrow 3CO_2+4H_2O$
