1) Calculate the mass of calcium that can react with 40 g of oxygen. moles O2 = = = 1.25 mol. moles Ca = 2 x 1.25 = 2.50 mol. mass Ca = . = 40 x 2.50 = 100 g. 2) Calculate the mass of fluorine that reacts with 3.9 g of potassium. moles K = . = . = 0.10 mol. moles F2 = . . = 0.050 mol. mass F2 = . = 38 x 0.050 = 1.9 g.
a) Write an unbalanced chemical equation, identifying the reactants and products. The equation cannot yet be balanced because vitamin C can only be represented as C x H y O z, where x, y, and z are integers to be determined in a later step in the problem solution. b) What is the reactant source of the carbon in the carbon dioxide product?
