7. if the poh of an rboh solution is 6.32, what is the concentration (molarity) of the base?

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

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.)

Anyone who's in connections academy chemistry b have the factors that affect the rate of a reaction portfolio already done?
