  1. 100g of copper beads were placed in a lidded jar (its mass is 150g). 5g of water was added and the jar was sealed tight. After 30 days, the copper hadcorroded and turned green. Before opening, the jar was placed on a balance scale and its mass was measured. What do you predict the mass was, and why do you predict that mass?
  1. 100g of a yellow powder reacted with 400g of a clear, colorless liquid. A lime green solution was formed and a black precipitate was formed during the reaction. After the reaction stopped, the precipitate was separated from the lime green solution, and it as found to have a mass of 50g. What was the mass of the remaining solution?
