Question

1.which of the following types of reaction is the opposite of a synthesis reaction ?

 

displacement 

combustion

reverisble

decompostion

Answer 1

Decomposition is the opposite of synthesis.

 

Decomposition is A ==> B + C

Synthesis is  B + C ==> A

 

Combustion is CH4 + 2O2 ==> CO2 + 2H2O

Displacement is A + BC ==> AC + B  or AB + CD ==> AD + CB

 

Reversible just means that the reaction goes in both directions.
