please give me it's answer​

Answer 1

Answer:

64+192=152+x

x=256-152

x=104

Answer 2

Answer:

it is kind of replaced reaction and the reactent mass will be equal to the total mass of the product.

thus, CA(64g)+ZnCo3(192g)

= CaCo3(152g)+Zn(x g)

64+192=256=152+x

x= 256-152

x= 104g

therefore the Zn is of 104 g
