Answer 1

An industrial process makes calcium oxide by decomposing calcium carbonate. Which of the following is NOT needed to calculate the mass of calcium oxide that can be produced from 4.7 kg of calcium carbonate?

Answer: Out of all the options presented above the one that is not needed to calculate the mass of calcium oxide that can be produced from 4.7 kg of calcium carbonate is answer choice D) The volume of unknown mass.

I hope it helps, Regards.

Answer 2

Based on the scenario, that is not needed to calculate the mass of the calcium oxide is : D. the volume of the unknown mass

In order to find out the mass of a product, you just need the mass of the reactants and the mass of the product

hope this helps
