Question

What is the balanced equation for the chemical reaction represented by: B2Br6 + HNO3 = B(NO3)3 + HBr?

A. B2Br6 + HNO3 = B(NO3)3 + HBr
B. B2Br6 + 3HNO3 = 2B(NO3)3 + 6HBr
C. 2B2Br6 + 3HNO3 = 3B(NO3)3 + 4HBr
D. 3B2Br6 + 2HNO3 = 2B(NO3)3 + 6HBr

Answer 1

The balanced chemical equation for the reaction B2Br6 + HNO3 = B(NO3)3 + HBr is B2Br6 + 3HNO3 = 2B(NO3)3 + 6HBr, which is option B in the multiple choices provided.

Step-by-step explanation:

To balance the chemical equation given in the question, we need to ensure that the number of atoms of each element on the reactant side equals the number of atoms of that element on the product side. Let's analyze the options one by one:

• 
  
• Option A: B2Br6 + HNO3 = B(NO3)3 + HBr. This is unbalanced as there are differing numbers of atoms on each side.
• 
  
• Option B: B2Br6 + 3HNO3 = 2B(NO3)3 + 6HBr. This is the balanced equation, as there are 2 B, 6 Br, 3 H, and 3 N atoms on both sides.
• 
  
• Option C and D are not balanced correctly.

Therefore, the balanced chemical equation for the reaction is: B2Br6 + 3HNO3 = 2B(NO3)3 + 6HBr, which corresponds to option B.
