Question

Choose the term that best describes the following chemical reaction:
C10H8 + 12 O2 10 CO2 + 4 H2O
A.synthesis
B.combustion
C.electrolytic
D.decomposition

Answer 1

the answer is B.combustion

Answer 2

Answer: B.combustion

Explanation:

Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.

Example: $Li_2O+CO_2\rightarrow Li_2CO_3$

Combustion is a type of chemical reaction in which fuel is reacted with oxygen to form carbon dioxide and water.

Example: $C_{10}H_8+12O_2 \rightarrow 10CO_2+4H_2O$

Electrolytic is a chemical reaction in which decomposition is carried by use of electric current.

Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

Example: $Li_2CO_3\rightarrow Li_2O+CO_2$

Thus $C_{10}H_8+12O_2 \rightarrow 10CO_2+4H_2O$ is combustion reaction.
