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

.
Well the answer to number 1 is definitely B
number 2 is B
number 3 is D
Number 4 is C
Hope this helps:)
The conversion factor between moles of calcium ion and moles of
in
would be 3 to 1.
<h3>Mole fraction</h3>
if formed from 3 carbon atoms and 3 phosphate atoms according to the equation:

Thus, there are 3 moles of calcium in every 1 mole of
.
The conversion factor between moles of calcium and moles of
will. therefore, be 3 to 1 or simply 3:1.
