Which of the following is the correctly balanced chemical equation for the reaction of Ca(OH)2 and HNO3?
Upper C a (upper O upper H) subscript 2 plus upper H upper N upper O subscript 3 right arrow upper C a superscript 2 plus, plus upper N upper O subscript 3 superscript minus.
Upper C a (upper O upper H) subscript 2 plus 2 upper H upper N upper O subscript 3 right arrow 2 upper H subscript 2 upper O plus 2 upper N upper O subscript 3 superscript minus
Upper C a (upper O upper H) subscript 2 plus upper H upper N upper O subscript 3 right arrow upper H subscript 2 upper O plus upper C a upper N upper O subscript 3.
Upper C a (upper O upper H) subscript 2 plus 2 upper H upper N upper O subscript 3 right arrow 2 upper H subscript 2 upper O plus UPper C a (upper N upper O subscript 3) subscript 2.

The correct balance equation for the reaction of Ca(OH)₂ and HNO₃ is:

Upper Ca (upper O upper H) subscript 2 plus 2 upper H upper N upper O subscript 3 right arrow 2 upper H subscript 2 upper O plus Upper Ca (upper N upper O subscript 3) subscript 2.

The equation for the reaction of Ca(OH)₂ and HNO₃ is given below:

Ca(OH)₂ + HNO₃ —> H₂O + Ca(NO₃)₂

The above equation can be balance as follow:

Ca(OH)₂ + 2HNO₃ —> H₂O + Ca(NO₃)₂

Ca(OH)₂ + 2HNO₃ —> 2H₂O + Ca(NO₃)₂

Now the equation is balanced.

Therefore, the correct answer to the question is:

Upper Ca (upper O upper H) subscript 2 plus 2 upper H upper N upper O subscript 3 right arrow 2 upper H subscript 2 upper O plus Upper Ca (upper N upper O subscript 3) subscript 2.

Upper C a (upper O upper H) subscript 2 plus 2 upper H upper N upper O subscript 3 right arrow 2 upper H subscript 2 upper O plus UPper C a (upper N upper O subscript 3) subscript 2.

The chemical equation can be written as

Ca(OH)2  + 2HNO3 → 2H20 + Ca(NO3)2

This means that 1 mole of  Calcium hydroxide reacts with 2 moles of Nitric acid and lead to the formation of 1 mole of Calcium nitrate plus 2 moles of water.
