WebHydrogen gains an electron (reduction) to go from a +1 oxidation state to zero as elemental hydrogen. Your task is to experimentally determine the empirical formula for zinc chloride. Procedure: 1- Determine what measurements are required. 2- After massing your zinc, determine how much HCl is required. 3- Carry out the reaction in the fume hood. WebIn the experiment, you exact weigh an pattern of magnesium metal, and then heat that sample in the air. Magnesium metal reacts with the oxygen (O2) of the air the form magnesium oxide. Mg + O2 ® magnesium oxide. After the magnesium free has reached completely, you determine the mass of magnesium oxyd product.
