Part b now that we have put a coefficient of 3 in front of caso4, what coefficient should go in front of cacl2 to balance calcium (ca)? 3caso4+alcl3→? cacl2+al2(so4)3 express your answer numerically as an integer.

The coefficient must be 3.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The number of atoms of each element has to be same on both sides, thus the balanced chemical reaction will be:

Thus a coefficient of 3 should go in front of to balance calcium (Ca).

it should be all of them because it asks if you included all of those in your answer
