Question

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?

Answer 1

14: mgcl2+na0
15:mgo+nacl
16: mgcl2+na20->mgo+2nacl
17:The reaction is a substitution reaction because Na has replaced Mg in its oxide.

Answer 2

2NaCl + MgO → MgCl₂ + Na₂O

This is a double displacement reaction because the part of one reactant is replaced by the part of another.
