Which chemical symbols will complete the equation for this decomposition reaction? 2ki->

2KI --> 2K + I2

I2 is becasue Iodine is an element that cannot stand alone, and therefore bonds with its self.

The chemical symbols completing the equation is

Explanation:

Decomposition reaction is defined as the reaction in which a single compound gets decomposed to two or more compounds.

General equation representing decomposition reaction follows:

The chemical equation for the decomposition of potassium iodide follows:

By Stoichiometry of the reaction:

2 moles of potassium iodide decomposes to form 2 moles of potassium element and 1 mole of iodine gas.

Hence, the chemical symbols completing the equation are

did anyone actually do this? like if anyone has submitted this i rly need .
