Question

In the reaction ca + f2 caf2 , what should be the coefficient for f2?

Answer 1

Answer : In the reaction of Ca + $F _{2}$ --->Ca$F _{2}$, the coefficient of Ca and $F _{2}$ will be the same which will be 1.

Explanation : As per the rules of writing a chemical equation and balancing it properly, the number of elements in reactants side should be equal to the number of elements generated in product side. Hence when we use 1 molecule of Ca and one molecule of $F _{2}$ then it generates 1 molecule of Ca$F _{2}$.
