My car has an internal volume of 3,600 L. If the sun heats my car from a temperature of 18.0 degrees Celsius to a temperature of 45.0 degrees Celsius, what will the pressure inside my car be? Assume the pressure a was initially 101.3 kPa.

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.)
