Question

Which chemical symbols will complete the equation for this decomposition reaction?

2KI → 2 + 2

Answer 1

2KI->2K+I2 is the equation.

Answer 2

Answer : Potassium (K) and iodide (I) are the chemical symbols.

Explanation :

Decomposition reaction : It is a type of chemical reaction in which a single compound decomposes into two or more compounds.

For example :    $AB\rightarrow A+B$

The Net balanced decomposition reaction is,

$2KI\rightarrow 2K+I_2$

So, Potassium (K) and iodide (I) are the chemical symbols.
