Answer:

The liquid decreases in temperature and its particles lose kinetic energy.

Temperature is proportional to kinetic energy, so if temperature decreases, kinetic energy decreases. Energy has been removed from the liquid, because it is in the air

If 4.65 LL of CO2CO2 gas at 22 ∘C∘C at 793 mmHg mmHg is used, what is the final volume, in liters, of the gas at 35 ∘C∘C and a p
otez555 [7]

Answer:

About 7.9 L.

Explanation:

We can utilize the ideal gas law. Recall that:

\displaystyle PV = nRT

Because the amount of carbon dioxide does not change, we can rearrange to formula to:
\displaystyle \frac{PV}{T}= nR

Because the right-hand side stays constant, we have that:
\displaystyle \frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} = nR

Hence substitute initial values and known final values:
\displaystyle \begin{aligned} \frac{(793\text{ mm Hg})(4.65 \text{ L})}{(22 \text{ $^\circ$C})} & = \frac{(743 \text{ mm Hg})V_2}{(35\text{ $^\circ$C})} \\ \\ V_2 & = 7.9\text{ L}\end{aligned}

Therefore, the final volume is about 7.9 L.

What is the [H+] concentration of a solution with a pH of 3.78
lianna [129]

Answer:

[H+] = 1.66 x 10^{-4}

Explanation:

To find the [H+] concentration of a solution, we can use the formula:

[H+] = 10^{-pH}

Let's plug in the pH.

[H+] = 10^{-3.78}

Evaluate the exponent.

[H+] = 1.66 x 10^{-4}

Hope this helps!
