1.
-Water levels are dangerously high for wildlife and humans.
-Animals seem to be lost, like the cow and the sheep especially.

2.
-There are not many trees near the water, meaning less areas for wildlife to live.
-There is not much wildlife in general.

Inferences
1. The wildlife shown will move relocate and adapt to another area.
2. Industry — emissions are visible in top left— will continue to hurt the environment. CO2 emissions will increase.

Good luck!

Whats is saturated solution? what happens as a saturated solution cools?
Darina [25.2K]
A saturated solution is a solution that contains a certain amount of solute that is enough to be dissolved in the solvent. Anything above that amount will not dissolve some of the solute in the solvent. When a saturated solution is cooled, the solubility of the solute lowers making the solution supersaturated.

A 1.78−L sample of hydrogen chloride (HCl) gas at 2.09 atm and 22°C is completely dissolved in 699 mL of water to form hydrochlo
patriot [66]

Answer:

M=0.960M

Explanation:

Hello,

In this case, it is firstly necessary to compute the dissolved moles of hydrogen chloride into the water as shown below:

n_{HCl}=\frac{PV}{RT}=\frac{2.09atm*1.78L}{0.082\frac{atm*L}{mol*K}*295.15K}=0.671molHCl

Thus, the molarity is computed as shown below:

M=\frac{0.671mol}{0.699L}=0.960M

Wherein no change in volume is considered, therefore the volume of the solution was the same volume of water.

Best regards.
