How many liters of 2.00 M H2SO4 must be diluted with water to prepare 0.1 of aqueous 0.400M H2SO4?

What is the mass of 0.46 mil of mgcl2

Select all that apply. using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 (s) pb+2(aq) + 2cl -(aq). the concentration of the products yield a ksp of 2.1 x 10-2:

Select the most likely product for this reaction: koh(aq) + co2(g) – ? k2co3(aq) + h2o(1) k(s) + h2(g) + o2(g) k(s) + co3(9) +h2
