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
MgO + NaCl (Reactant)
15. Show the formulas of the products.
MgCl2 + Na2O (Product)

16. Write the balanced the equation for this reaction.
Balancing: MgO + 2 NaCl = MgCl2 + Na2O

17. What type of chemical reaction is this?
The type of chemical reaction, it's a Double Displacement reaction. How do you know? Because you part of one reactant is replaced by part of another reactant.
