Many metals react with oxygen gas to form the metal oxide. For example calcium reacts:
2Ca(s) + O2(g)--> 2CaO(s)
Calculate the mass of calcium prepared from 4,20g of Ca and 2.80g of O2. (a) How many moles of CaO can form from the given mass of Ca? (b) How many moles of CaO can form from the given mass of O2? (c)What is the limiting reactant? (d) How many grams of CaO can be formed?
