Predicting Common Reactions
With the reactants listed write the balanced chemical reaction that would result. write subscripts as normal script so ammonium sulfate would be written as (NH4)2SO4. Put a space before and after each formula and yield sign. Use the hyphen and greater than sign to make the yield sign as " -> ". Assume polyvalent metals will have the lowest charge possible (see the chart on page 221)

| A | B |
| potassium + oxygen | 2K + O2 -> 2K2O |
| magnesium + oxygen | 2Mg + O2 -> 2MgO |
| aluminum + oxygen | 2Al + 3O2 -> 2Al2O3 |
| calcium + sulfur | 8Ca + S8 -> 8CaS |
| zinc + sulfur | 8Zn + S8 -> 8ZnS |
| sodium + chlorine | 2Na + Cl2 -> 2NaCl |
| iron + sulfur | 8Fe + S8 -> 8FeS |
| cobalt + oxygen | 2Co + O2 -> 2CoO |
