What do the reactant and the product tell us about the molar ratio?
The coefficients in front of the products and reactants give the molar ratio.
The coefficients are the numbers in front of each molecule or element.
The coefficient for Hydrogen is 2
The coefficient for Oxygen is 1
The coefficient for Water ( Hydrogen Oxide) is 2
The ratio for molar ratio of Hydrogen to water is 2/2
The ratio for molar ratio of Oxygen to water is 1/2
The molar ratio depends on the coefficients in the balanced chemical equation.
