Balancing Chemical Equations

1. Do Now Activity- For Collection Utilizing the following chemical reaction, identify and list in separate columns the reactants and products, Balance the equation and calculate the molar mass of each compound Al(s) + NH4ClO4(s) Al2O3(s) + AlCl3(s) + NO(g)+ H2O(g) 3 1 3 3 1 6

2. Al(s) + NH4ClO4(s) Al2O3(s) + AlCl3(s) + NO(g)+ H2O(g) Reactants Al NH4ClO4 Products Al2O3 AlCl3 NO H2O

3. Al(s) + NH4ClO4(s) Al2O3(s) + AlCl3(s) + NO(g)+ H2O(g) Al: 27 g/mole NH4ClO4: 117 g/mole Al2O3: 102 g/mole AlCl3: 132 g/mole NO: 30 g/mole H2O: 18 g/mole
