Question

Which is a characteristic of a synthesis reaction

A.There is more than one reactant
b.The general formula is a-b+c
c.all reactants are elements
d.more than one product forms

Answer 1

Answer:option A
Multiple reactants are used to form one product.

Answer 2

Answer : The correct option is, (A) There is more than one reactant.

Explanation :

Synthesis reaction : Synthesis reaction are those reactions in which more than one reactants react to form a single product or a compound.

The general representation of the synthesis reaction is,

`A+B\rightarrow AB`

In this, A and B are the reactants and AB is the product.

For example : formation of calcium hydroxide from calcium oxide and water.

`CaO(s)+H_2O(l)\rightarrow Ca(OH)_2(s)`

Hence, the correct answer is, (A)
