Phenobarbital has a pka = 7.4. Compared to a 1.0 x 10^-3 M solution, 1.0 x 2 10^-4 M phenobarbital will have a (higher, lower) pH and a _(higher, lower) percent ionization. *​

What is the mass of each element in a 324.8 sample of co2

How many grams of mgbr2 are needed to produce 75g or metal?

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.)
