It has been proposed that north america is moving west at about 2 cm per year. how many kilometers would it move in 5,000 years? (note: 2 cm is a measurement so your final answer should have significant figure rules applied.)

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.)

What is the measured amount of a product obtained from a chemical reaction?
