Multiplying the gas volume by the increased carbon dioxide concentration and dividing by the weight and sampling duration would then calculate the carbon dioxide production rate.

Calcium hydroxide and calcium sulfate are both used to prepare a saturated solution, S. Both
solids are only sparingly soluble, and the pH of S is found to be 11.6.
(i) Given that the Ksp for calcium hydroxide is 4.0 x 10-5
and the Ksp for calcium sulfate is
2.5 x 10-5
, determine the concentration of sulfate ions present in S.

150g of a gas at 10.0°C and 1.0 atm pressure occupies 913L volume. The volume of the gas increases to 988L and its temperature increases to 41.5°C while the pressure remains constant. Calculate ΔE, q and w for the gas. (Specific heat of the gas = 5.2J/g°C and 1L.atm = 101.3J).
