Final answer:
To determine the maximum amount of CaO produced by burning calcium, you need the mass of calcium, calculate its moles using its molar mass, find the moles of CaO from the reaction stoichiometry, and then convert those moles to grams using the molar mass of CaO.
Step-by-step explanation:
To calculate the maximum amount of CaO (calcium oxide) that can be produced by burning calcium metal, you would need the mass of the calcium metal used. The burning of calcium metal in oxygen results in CaO according to the chemical equation:
2 Ca(s) + O2(g) → 2 CaO(s)
According to the stoichiometry of the reaction, each mole of calcium metal reacts with half a mole of oxygen gas to produce one mole of calcium oxide.
Therefore, if the mass of the calcium metal is known, you can calculate the moles of calcium using its molar mass (40.08 g/mol), then use the mole ratio from the balanced equation (2:2) to find the moles of CaO produced.
Finally, you can convert the moles of CaO to grams using the molar mass of CaO (56.08 g/mol).
