Balancing molecular equation for reaction of calcium


Assignment:

Q1) Write the balanced molecular equation for the reaction of calcium with molecular oxygen to form calcium oxide.

Q2) You start out with an empty crucible weighing 19.3350g. After adding some calcium to the crucible, the mass is now 22.1156g. After heating the calcium and completely converting it to the oxide, the mass of the crucible is now 25.7701g. Find the mass of the calcium and oxygen in the oxide.

Provide complete and step by step solution for the question and show calculations and use formulas.
