You are on a relaxing cruise in the warm waters of the Caribbean. All of a sudden, your yacht hits a reef and begins to go down. You and your friends start to pump up the little yellow life raft. You are all working in the shade of the sails, where it is cool. They say the raft should be blown up to its maximum volume. You, knowing about gas laws from chemistry, argue that it should only be blown up about 80% full. Explain, using gas law terms, why your option is the best.

If 1.8 l of water is added to 2.5l of a 7.0 m koh solution, what is the molarity of the new solution

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
