Question

Write an equation for the reaction of magnesium oxide with sodium chloride to produce magnesium chloride and sodium oxide.

1. Show the formulas of the reactants.
2. Show the formulas of the products.
3. Write the balanced the equation for this reaction.
4. 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

Reactants:
1)Magnesium oxide: MgO
2)Sodium chloride: NaCl
Products:
1) Magnesium chloride: MgCl₂
2) Sodium oxide: Na₂O
Equation:
MgO + 2NaCl ⇒ MgCl₂ + Na₂O
The reaction is a substitution reaction because Na has replaced Mg in its oxide.
