1. True or False? In general, atoms of metals lose electrons to form cations, and are therefore oxidized;
while atoms of nonmetals gain electrons to form anions, and are therefore reduced.
2. Identify which reactant is undergoing oxidation and which is undergoing reduction.
Mg + O? ? MgO
3. Solid sodium reacts with aqueous copper (II) chloride produces aqueous sodium chloride and solid
copper. Identify which reactant is undergoing oxidation and which is undergoing reduction.
4. What is the molecular mass of manganese(II) phosphate?
5. How many molecules of manganese (II) phosphate are there in 25.0 g of manganese(II) phosphate.
6. How many moles of carbon are there in 1.50 moles of butane, C4H10?
7. Calculate the molarity of 25.0 g of CoCl? dissolved in an aqueous solution with a total volume of 125.0
mL.
8. If 0.50 L of a 5.00-M solution of copper nitrate, Cu(NO3)2, is diluted to a volume of 1.75 L by the
addition of water, what is the molarity of the diluted solution?
