Answer:
The answer to the question is letter a. 2
Explanation:
Write the formula of each compound
Calcium hydroxide = Ca(OH)₂
Nitric acid = HNO₃
Water = H₂O
Calcium nitrate = Ca(NO₃)₂
Chemical Reaction
Ca(OH)₂ + HNO₃ ⇒ Ca(NO₃)₂ + H₂O
Reactants Elements Products
1 Ca 1
1 N 2
3 H 2
5 O 7
Balanced Chemical Reaction
Ca(OH)₂ + 2HNO₃ ⇒ Ca(NO₃)₂ + 2H₂O
Reactants Elements Products
1 Ca 1
2 N 2
4 H 4
8 O 8
The answer is
A + oxygen ➡ energy
