What is the temperature of o3 gas if the average speed(actually the root mean square speed of the molecules is 750 m/s

What are transitions between a liquid and gas called? identify which way they are transitioning

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.)

If the solubility of a gas in water is 1.22g/2.75 atm, what is it’s solubility (in g/l) at 1.0 atm
