PLEASE PLEASE PLEASE PLEAS 2. Assume the reaction goes to completion, and the volumes are additive, when 45.0 ml of a 0.54 M solution of barium nitrate is combined with 35.0 ml of 0.54 M sodium phosphate solution,
a. calculate the mass of the precipitate that should form.
b. If 3.32 g of precipitate did form in the laboratory, calculate the % yield.
c. Determine the concentration (molarity) of each ion still floating in the solution.

Which of your 24 wells had indications that a chemical reaction occurred? how were you able to tell that a chemical reaction occurred? which of your 24 wells had indications that a physical reaction occurred? how were you able to tell that a physical reaction occurred? report on both mixing and evaporation. make a general statement about whether your hypotheses were validated or rejected. must your hypotheses be correct for this to be a successful laboratory?
