2. If the magnesium does not completely react with oxygen, how will the final results be affected? 3. If the water is not completely removed in the final heating step, how will the final results be affected? 4. Using the periodic table, determine the formula of the magnesium nitride by- ed in the combustion of air. If this were not treated with water to product form convert it to magnesium oxide, how would the final results have been affected?

Write the balanced chemical equation for the formation of magnesium oxide from magnesium and elemental oxygen. 1. Write the balanced chemical equation for the formation of magnesium nitride from magnesium and elemental nitrogen. 2. Write the balanced chemical equation for the conversion of magnesium nitride to magnesium oxide as performed in steps 7-8 in the procedure. The reaction produces magnesium oxide and ammonia (NH,). 3. If some of the product contained magnesium nitride rather than magnesium oxide, would the experimental...

1. The crucible is not fired, as the procedure suggests. The mass of the dirty crucible is recorded. However, the impurities are burned off in the experiment. Will the reported mass of the final product be too high, too low, or unchanged as a result of this technique error? Too high Too low Unaffected 2. If you put more water than is needed for reaction 3, and then did not dry out this excess water, what effect (if any) would...

2. If the strips of Mg ribbon are coated with white MaO, would this cause the mass of Mg that you calculate to be too high or too low? Why? Eleme flame 3. Instead of a strip o f pure Mg ribbon, you are accidentally given a strip of an aluminum-magnesium alloy. You calculate the mass of the strip as above. Would the mass of the strip expected? Write t be high or lower than he appropriate chemical equations (one...

The correct formula form sometimes in this experimenti 0.9 Mg to 1.0 0) In that case, it mean sium oxide is MgO, a 1.0 to 1.0 ratio. But periment the ratio of Mg to O comes out too low. (Example se, it means that there was too much oxygen relative 1 f magnesium. At other times it comes out that the ratio is too large A vould be: 1.2 to 1.0 (Mg to O). In such a case it must...
