Suppose that CO2 in the atmosphere was held at a constant, natural level for a few thousand years. Then, CO2 was added to double
jasenka [17]

Answer: Temperature before the increase in CO_2 was a few degrees lower than temperature after the increase.

Explanation:

According to Charle's Law which states that The volume of gas is directly proportional to the temperature of the gas, when pressure is kept constant.

(Volume)\propto (Temperature)

\frac{volume}{temperature}=constant (At constant Pressure)

With the increase in level CO_2 in atmosphere the increase in temperature of the atmosphere will be observed.

Hence, temperature before the increase in CO_2 was a few degrees lower than temperature after the increase.

What is the morality of a solution made with 0.88 moles of KCl and 2.0 L of water?
Anarel [89]

Answer:

M=0.44M

Explanation:

Hello,

In this case, the molarity is defined as the ratio of the moles of the solute to the volume of the solution in liters:

M=\frac{n_{solute}}{V_{solution}}

In this case, the solute is the KCl (potassium chloride) and the solution is made up of both water and KCl. Moreover, since during this type of dissolution processes, the volume of the solution is not significantly affected by the addition of the solute, the resulting molarity is:

M=\frac{0.88mol}{2.0L}\\ \\M=0.44M

Best regards.
