Text Solution

Verified by Experts

The correct Answer is:
C
`[Ca to Ca^(2+) + 2e^(-)] xx 3`
`[Al^(3+) + 3e^(-) to Al] xx 2`
`3ca to 3Ca^(2+) + 6e^(-)`
`2Al^(3+) + 6e^(-) to 2Al`
`overline(3Ca + 2Al^(3+) to 3Ca^(2+) + 2Al)`
Therefore, the stoichiometric coefficient of Ca in the given reaction is 3.
