You need to make 2.00 L of a calcium hydroxide solution with pH= 12.50. What mass of the solid must be dissolved? (Note: the solubility of calcium hydroxide is 1.7 g/L at 20 degrees c, so long as this limit is not approached, the relatively low solubility of the compound does not preclude making this solution. )

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

Calculate the concentration of all species in a 0.165 m solution of h2co3.

An unknown insoluble substance displaced the water shown. it's mass is indicated on the triple beam balance. mass = a. 694 b. 693.5 c. 693.0 d.693.8
