Question
Fill in the blanks with a coefficient:
_ HCl + H3PO4 → PCl5 +_ H2O
- 5, 4
- 1, 6
- 3, 8
- 2, 2
Hint:
Balance this chemical reaction by oxidation number method. After balancing the oxidation numbers of the atoms on both sides, need to balance the remaining atoms O and H by the hit and trial method.
The correct answer is: 5, 4
Fill in the blanks with a coefficient:
5 HCl + H3PO4 → PCl5 +4 H2O
