A student has 4.60 g of zinc powder, 1.35 L of a 3.20 M calcium nitrate solution, and 1.70 L of a 3.30 M lead(II) nitrate solution. Using the activity series, which of these two solutions will react with the zinc powder? calcium nitrate lead(II) nitrate Write the chemical reaction that occurs between the two reacting species. Include physical states. molecular equation: What volume of the solution is needed to completely react all 4.60 g of zinc powder? volume: L Calculate the molarity of the Zn2+ ions in solution after the reaction. concentration: M
