1. Magnesium metal (Mg(s)) burns brightly in oxygen gas (o2(g)) to produce a whitish-grey powder, magnesium oxide (MgO(s)). Write a balanced chemical equation for this reaction. 2. Magnesium metal (Mg(s)) will also react with copper ion in solution (Cu+2(aq)) to form magnesium ions in solution (Mg+2(aq)) and copper metal (Cu(s)). Write a balanced chemical equation for this reaction. 3. A solution of sodium carbonate (Na2CO3(aq)) will react with a solution of calcium chloride (CaCl2(aq)) to produce the solid precipitate, calcium carbonate (CaCO3(s)) and a solution of sodium chloride (NaCl(aq)). Write a balanced chemical equation for this reaction.
