  1. Highland Science Department Mass Relationships in Chemical Equations

  2. Highland Science Department Mass Relationships in Chemical Equations Mole Ratio: indicates the relationship between the number of moles of different chemicals used or produced in chemical reactions

  3. Highland Science Department Mass Relationships in Chemical Equations Mole Ratio: indicates the relationship between the number of moles of different chemicals used or produced in chemical reactions -comes from the coefficients of a balanced chemical equation

  4. Highland Science Department Mass Relationships in Chemical Equations e.g. N2(g)+H2(g) NH3(g)

  5. Highland Science Department Mass Relationships in Chemical Equations e.g. N2(g)+3H2(g) 2NH3(g)

  6. Highland Science Department Mass Relationships in Chemical Equations e.g. N2(g) + 3H2(g) 2NH3(g) mole ratios: 1 mol N2 or 3 mol H2 3 mol H2 2 mol NH3

  7. Highland Science Department Mass Relationships in Chemical Equations e.g. N2(g)+3H2(g) 2NH3(g) mole ratios: 1 mol N2 or 3 mol H2 3 mol H2 2 mol NH3 -knowledge of chemical equations and moles can be used to calculate mass relationships among the substances involved in a chemical reaction

  9. Highland Science Department Mass Relationships in Chemical Equations e.g. 1. How many moles of oxygen are required to react with 9.7 g of magnesium to produce magnesium oxide?

  10. Highland Science Department Mass Relationships in Chemical Equations e.g. 1. How many moles of oxygen are required to react with 9.7 g of magnesium to produce magnesium oxide? answer: 0.20 moles e.g. 2. How many grams of KClO3 must be decomposed to give 0.96g of oxygen?

  11. Highland Science Department Mass Relationships in Chemical Equations e.g. 1. How many moles of oxygen are required to react with 9.7 g of magnesium to produce magnesium oxide? answer: 0.20 moles e.g. 2. How many grams of KClO3 must be decomposed to give 0.96g of oxygen? answer: 2.5 g e.g. 3. If 6.80 g of ammonia is used in the following reaction, what mass of oxygen is required to consume all the ammonia? NH3 + O2 NO + H2O

  12. Highland Science Department Mass Relationships in Chemical Equations e.g. 1. How many moles of oxygen are required to react with 9.7 g of magnesium to produce magnesium oxide? answer: 0.20 moles e.g. 2. How many grams of KClO3 must be decomposed to give 0.96g of oxygen? answer: 2.5 g e.g. 3. If 6.80 g of ammonia is used in the following reaction, what mass of oxygen is required to consume all the ammonia? NH3 + O2 NO + H2O answer: 16.0 g
