Question

Solid silver chloride, AgCl(s), decomposes to its elements when exposed to sunlight.

Answer 1

Answer: The coefficient of silver chloride in the chemical reaction is 2

Explanation:

Decomposition reaction is defined as the reaction in which a single large substance breaks down into two or more smaller substances.

The general equation for the decomposition reaction follows:

$AB\rightarrow A+B$

When silver chloride decomposes when exposed to sunlight, it produces silver metal and chlorine gas

The chemical equation for the decomposition of silver chloride follows:

$2AgCl(s)\rightarrow 2Ag(s)+Cl_2(g)$

By Stoichiometry of the reaction:

2 moles of solid silver chloride decomposes to produce 2 moles of silver metal and 1 mole of chlorine gas

Hence, the coefficient of silver chloride in the chemical reaction is 2

Answer 2

Answer:

Explanation:

First of all it is decomposition reaction , since

AgCl is being decomposed to form Ag and Cl 2

Since the reaction is occurring in light it is called photodecomposition or

photodissociation or photolysis reaction
