Answer:

2HNO3 + Ca(OH)2 → 2H2O + Ca(NO3)2

Explanation:

HNO3 + Ca(OH)2 → ?

This is an acid-base reaction. It is also a double displacement reaction, in which the positive ions change partners.

Thus, H pairs with OH and Ca pairs with NO3.

HNO3 + Ca(OH)2 → HOH + Ca(NO3)2

HOH is our old friend, H2O (water) so, after balancing atoms, the equation becomes:

2HNO3 + Ca(OH)2 → 2H2O + Ca(NO3)2
