A student has 3.75 g of zinc powder, 1.85 L of a 3.50 M calcium nitrate solution, and 1.50 L of a 3.20 M lead(II) nitrate solution. Using the activity series, which of these two solutions will react with the zinc powder?

a. calcium nitrate
b. lead(II) nitrate

Write the chemical reaction that occurs between the two reacting species. Include physical states.

What volume of the solution is needed to completely react all 3.75 g of zinc powder?

Calculate the molarity of the Zn2+ ions in solution after the reaction.

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
