Question

What would the products of a double-replacement reaction between ca3n2 and al2o3 be?

Answer 1

The equation for the reaction between Ca3N2 and Al2O3 wiil be; 
  Al2O3 + Ca3N2 = 2AIN +3CaO
Thus, the products of the reaction will be Aluminium Nitride and Burnt lime(Calcium oxide). A double displacement reaction, also known as a double replacement reaction or metathesis, is a reaction where two compounds react, and the positive ions and the anions switch places, forming two new compounds or products.
