Answer:
The statement that correctly explains the graph attached is: "As temperature rises, gas particles are moving faster and may leave the solution."
We know that the solubility of a gas decreases with increasing temperature. This stems from the fact that the kinetic energy and velocity of gas molecules increases with increase in temperature.
That means that as a the temperature of a gas increases, its molecules move faster and are more likely to escape from solution rather than enter the solution.
This explains the decrease in the solubility of a gas with increase in temperature.
Explanation:
Answer: Pumping can affect the level of the water table. In an aquifer, the soil and rock is saturated with water.

12 x 10^23 atoms, i hope this helps
When two element combine to form more than one compound i hope this helps you with work have a nice day :)
The amount of sample that is left after a certain period of time, given the half-life, h, can be calculated through the equation.
A(t) = A(o) (1/2)^(t/d)
where t is the certain period of time. Substituting the known values,
A(t) = (20 mg)(1/2)^(85.80/14.30)
Solving,
A(t) = 0.3125 mg
Hence, the answer is 0.3125 mg.
