Two students went to the science museum and saw an exhibit about trout. They learned that trout eat mayfly
nymphs and dragonfly nymphs. They thought it was interesting that the dragonfly nymphs also eat the mayfly nymphs.
The mayflies feed on algae growing on rocks in rivers. Some of the trout are caught by ospreys (large birds) that swoop
down and pluck the trout out of the water. One student thought it would be fun to make a food web of the trout
stream ecosystem. When he showed it to the other student, she thought it needed a little more work. What corrections
and additions do you think she suggested to him?

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.)
