For each equation, write all possible mole ratios. A. 2HgO (s) >2Hg (l) + O2 (g) B. 4NH3 (g) + 6NO (g) >5N2 (g) + 6H2O (l)

Mole ratios represent quantities of substances in the chemical equation by proportion. Each answer can be stated in vice versa.

Answers for A are the following:

2 moles of HgO form 2 moles of Hg

2 moles of HgO form 1 moles of O2

2 moles of Hg to 1 mole of O2

Answers for B are the following:

4 moles NH3 to 6 moles NO

5 moles N2 to 6 moles H2O

4 moles NH3 to 5 moles N2

4 moles NH3 to 6 moles H2O

6 moles NO to 5 moles N2

6 moles NO to 6 moles H2O
