In chemistry, some reactions are linked to other reactions. For example, in the decomposition of potassium chlorate, oxygen and
potassium chloride are produced. Then, the oxygen can react with magnesium and produce magnesium oxide. Using the reactions below, if you start with exactly 6 moles of potassium chlorate, how much magnesium oxide can you produce? 2 KClO3 → 3 O2 + 2 KCl 2 Mg + O2 → 2 MgO A. 18 moles
B. 5 moles
C. 6 moles
D. 2 moles
Probably the easiest method to separate the two substances is to dissolve salt in water, pour the liquid away from the sand, and then evaporate the water to recover the salt.
