Question

Which of the following statements is true for a synthesis reaction? A single product is formed. Multiple products are formed. A single reactant breaks down. Multiple reactants break down.

Answer 1

Answer : The correct option is, A single product is formed.

Explanation :

• Synthesis reaction : It is defined as the chemical reaction in which the multiple substances or the reactants combines then it forms a single product.

The synthesis reaction is represented as,

$X+Y\rightarrow XY$

For example : When the hydrogen gas react with oxygen gas then its forms water as a single product.

The balanced chemical reaction will be :

$2H_2+O_2\rightarrow 2H_2O$

• Decomposition reaction : It is defined as a type of reaction in which a single larger compound decomposes to give two or more or multiple smaller molecules as a product.

The general representation of decomposition reaction is :

$AB\rightarrow A+B$

For example : When nitrogen dioxide decomposes then it gives oxygen gas and nitrogen gas as a products.

$2NO_2\rightarrow 2O_2+N_2$

Hence, the true statements for a synthesis reaction is, a single product is formed.

Answer 2

Answer: A single product is formed.

Explanation: Synthesis reaction is one in which two or more substances react together to form a single product.

$N_2+3H_2\rightarrow 2NH_3$

A reaction in which a single reactant breaks down to form two or more than two products is called as decomposition.

$CaCO_3\rightarrow CaO+CO_2$
