Question

Mole ratios how can the coefficients in a chemical equation be interpreted

Answer 1

The coefficient in a balanced chemical equation indicates the mole ratio of both reactants and products.

Step-by-step explanation:

For example lets consider the reation between Hydrogen and Oxygen to form water:

2H2 + O2 ----------------------- 2H2O

In this reaction, the coefficients of the balanced reaction can be transformed to Mole ratio according to Avogadro's Law which states that at standard temperature and pressure, equal volume of gases contain the same number of moles.

So the mole ratio for the above equation is the ratio of the coefficient:

2moles : 1 mole : 2 moles
