Question

This examination is open book. You have 50 minutes to complete it. The total worth is 100 points plus 10 points. All answers must be provided on the answer sheet. The value of the equilibrium constant expression K is a constant for a particular reaction at a given temperature, and that this value is (dependent or independent) of the aquarium concentrations of the chemicals substituted into the equation. A solution that has a [H*] concentration of 10^-4 M has a pH of. Henry's law states that, at equilibrium, the partial pressure of a chemical in phase is linearly proportional to the convention of the chemicals in phase. In a closed system, the concentration of carbonate species is constant and equals to the two common catabolic, energy-yielding pathways are: The term trophic is used to describe the level of nourishment. Based on types of energy sources used by the organisms, the trophic level can be divided into and in a material balance problem, the situation where the rate of accumulation is zero is to as The first Jaw of thermodynamics states that: Eutrophication results primarily from an increase in the concentration(s) of and/or in lakes and/or marine system The average linear velocity of water in an aquifer is always the Darcy velocity in the same formation.

Explanation / Answer

Q1.

it is clearly dependent of the equilibrium concentrations of the chemicals substituted, since

K = [products]^p/[reactants]^r so increase/decrease in each of thenm chanes K

Q2

pH = -log(H+) by definition

so

pH =-log(10^-4) = 4

Q3.

LIQUDI / GAS phase... we care about solubility of gases in liquids....

so choose liquid phase first, then gas phase

Q4.

CO2 = H2CO3 + HCO3- + CO3-2
