In the reaction ca + f2 caf2 , what should be the coefficient for f2?
1 answer:
Answer : In the reaction of Ca + 
--->Ca, the coefficient of Ca and 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 then it generates 1 molecule of Ca.

Answer:
613 mg
Explanation:
Number of fargday's
Here, I = 9.20 A
t = 10.5 min
= 10.5 x 60 seconds
So,
= 0.0208 F
Here, 2e, 2F
2F = 1 mol of Ni
1 mol = 59 gm of Ni
0.0104 mol = 59 x0.0104 gm Ni
= 0.613 gm Ni
= (0.613 x 1000 ) mg of Ni
= 613 mg of Ni
