To predict the products of the chemical reaction between HNO3 and Ca(OH)2 (Nitric acid and Calcium hydroxide), we first need to recognize the type of reaction that will take place.

Because HNO3 is an acid and Ca(OH)2 is a base, we have a neutralization reaction. Based on this information, we can predict that the products will be calcium nitrate Ca(NO3)2 and water H2O.

This reaction is a prime example of an acid-base reaction, where the acid and base neutralize each other's properties, resulting in the formation of a salt and water. This allows us to figure out the products of the reaction between HNO3 and Ca(OH)2.
