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

B.combustion

Explanation:

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

Example:

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

Example:

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:

Thus is combustion reaction.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
