Question

Somebody please give me a answer, I asked this question before and some dude didn’t help at all. So it would make my day if somebody helped me.

All substances taking part in a certain interaction are shown below:
Calcium Carbonate = Calcium Oxide + Carbon dioxide
112 g
88 g

Which of the following is the correct estimate of the amount of calcium carbonate used in the interaction?

Sum of 112 g and 88 g

Difference between 112 g and 88 g

Twice the sum of 112 g and 88 g

Twice the difference between 112 g and 88 g

Answer 1

sum of 112g and 88g

Step-by-step explanation:

according to the law of conservation of mass which one of the laws of a chemical rxn: the mass of the reactant and the product is equal which also means that matter neither created nor destroyed in a chemical rxn.

so if CaCO3 is completly decomposed to CaO and CO2, it have a mass which is the sum of the products

Mass of CaCO3= 112g +88g

= 200g

Answer 2

The law of conservation of mass states that "mass can neither be created nor destroyed in a chemical reaction." Thus, the sum of reactants should be equal to the sum of the products.

In the given case, Calcium Carbonate is the product.

112 g of Calcium Oxide is used and 88 g of Carbon Dioxide is used.

therefore, the amount of calcium carbonate will be the sum of 112 g and 88 g

hope i helped!
