For questions #14 – 17, write an equation for the reaction of magnesium oxide with sodium chloride to produce magnesium chloride and sodium oxide.
14. Show the formulas of the reactants.
15. Show the formulas of the products.
16. Write the balanced the equation for this reaction.
17. What type of chemical reaction is this? How do you know?
2NaOH + MgCl2 -> Mg(OH)2(s) + 2NaCl
It would be a double replacement reaction and I doubt if it occurs in real life. Everything but the resulting solid precipitate Mg(OH)2 is ions in solution.
I agree with Damon

To answer questions #14-17, let's break it down step by step:
14. The reactants in the equation are magnesium oxide and sodium chloride. The formula for magnesium oxide is MgO, and the formula for sodium chloride is NaCl.
15. The products of the reaction are magnesium chloride and sodium oxide. The formula for magnesium chloride is MgCl2, and the formula for sodium oxide is Na2O.
16. To write a balanced equation for the reaction, we need to ensure that there are an equal number of atoms on both sides of the equation. The balanced equation for this reaction is:
2MgO + 2NaCl → MgCl2 + Na2O
17. This is a double displacement or metathesis reaction. We know this because the reactants (magnesium oxide and sodium chloride) exchange ions to form the products (magnesium chloride and sodium oxide). In this case, the magnesium and sodium ions swap partners with the chloride and oxide ions, respectively.
