Question
Pt + HNO3 + HCl --> H2PtCl6 + NO2 + H2OAfter balancing, what is the sum of the coefficients?
Solution
First, we need to balance the chemical equation. The balanced equation is:
Pt + 8 HNO3 + 6 HCl --> H2PtCl6 + 8 NO2 + 4 H2O
Now, we add up the coefficients:
1 (for Pt) + 8 (for HNO3) + 6 (for HCl) + 1 (for H2PtCl6) + 8 (for NO2) + 4 (for H2O) = 28
So, the sum of the coefficients is 28.
