Final answer:
The products of the chemical reaction between Sr(OH)₂ and HNO₃ are strontium nitrate (Sr(NO₃)₂) and water (H₂O), matching with option A.
Step-by-step explanation:
The products of the chemical reaction between Sr(OH)₂ and HNO₃ are Sr(NO₃)₂ and H₂O. When Sr(OH)₂, which is a strong base, reacts with HNO₃, a strong acid, the products formed are a salt and water. This type of reaction is known as a neutralization reaction. To balance this reaction, we can see that two HNO₃ molecules are needed to react with one Sr(OH)₂ molecule to produce one Sr(NO₃)₂ molecule and two H₂O molecules. The balanced chemical equation for this reaction is Sr(OH)₂ + 2HNO₃ → Sr(NO₃)₂ + 2H₂O, which matches with option A.
