The reaction equation is the chemical formula of reagents and product substances

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

2Na(s) + Cl₂(g) → 2NaCl(s).

mol Na :

mol NaCl :

limiting reactant = Na(mol NaCl from mol Na, mol ratio : 2 : 2)

mol Cl₂:mol Na=2:1

mol Cl₂ =

mass Cl₂ :

MW Cl₂ = 71 g/mol
