Calculate the difference in pressure between the top and the bottom of a container exactly 84 cm deep filled at 27 ℃ with: Water (d = 0.990 g/cm3 )
Copper (d = 13.6 g/cm3 )

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!
