What is the mole ratio of magnesium to hydrogen?
A balance chemical equation shows the ratio in which substances react and are produced. This is called the stoichiometry of a reaction. This balanced chemical equation shows that 1 mole of magnesium reacts with 2 moles of hydrochloric acid to form 1 mole of magnesium chloride and 1 mole of hydrogen.
What is the mole ratio of HCl MgCl2?
There is a 1:1 molar ratio between magnesium and magnesium chloride.
What is the ratio of Mg H2?
You can see that there is a 1:1 ratio for every mole of Mg reacted to Hydrogen gas produced. So if two moles of Mg were to react, 2 moles of H2 would be produced.
What is the mole ratio between Mg and MgO?
The ratio of MgO to Mg in the given chemical equation is 2:2, thus the number of moles of MgO formed is equal to the number of moles of Mg reacted.
What mole ratio would be used to go from moles HCl to moles Mgcl 2?
Notice that you have a 1:2 mole ratio between magnesium metal and hydrochloric acid. This tells you that the reaction will always consume twice as many moles of hydrochloric acid as you have moles of magnesium metal taking part in the reaction.

How is mole ratio used in chemical calculations?
Mole ratios are used as a means of comparison of substances in a balanced chemical equation in order to determine amounts. How many moles of Hydrogen gas are necessary to react with 5 moles of Nitrogen. We can use conversion factors in a process called stoichiometry. Mole ratio provides a comparison to cancel units.
How do you find mole ratios in a chemical equation?
Once you know the number of moles of each component of the compound, you divide each by the one with the lowest number and round to the nearest integer. The numbers are the mole ratios, and they appear as subscripts in the empirical formula.
