Question

Type the correct answer in each box.

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

2KI → 2 + 2

Answer 1

2KI → 2K + I₂

Step-by-step explanation:

(not my definition, but form a trustworthy source)

The definition of a decomposition reaction is:

a chemical reaction in which one reactant breaks down into two or more products.

In this case, potassium iodide will decompose into potassium and iodine.

2KI → 2K + 2I

2 Potassium and 2 Iodine on both sides, so equation is balanced.

Or, it can be written as 2KI → 2K + I₂
