Answer:
Having as wide a range of organisms as possible.
Hope it helps! :)
C because its meters right
The balanced chemical formula should be Al2(SO4)3 + 6NaOH = 2Al(OH)3 + 3Na2SO4
Therefore the coefficient of Al(OH)3 is 2!
Hope that helps :)
Add an alkaline compound to raise the pH to 7.2.
<u>Answer:</u> The temperature when the volume and pressure has changed is 274 K
<u>Explanation:</u>
To calculate the pressure when temperature and volume has changed, we use the equation given by combined gas law. The equation follows:

where,
are the initial pressure, volume and temperature of the gas
are the final pressure, volume and temperature of the gas
We are given:
![P_1=760mmHg\\V_1=175L\\T_1=15^oC=[15+273]K=288K\\P_2=640mmHg\\V_2=198L\\T_2=?K](https://tex.z-dn.net/?f=P_1%3D760mmHg%5C%5CV_1%3D175L%5C%5CT_1%3D15%5EoC%3D%5B15%2B273%5DK%3D288K%5C%5CP_2%3D640mmHg%5C%5CV_2%3D198L%5C%5CT_2%3D%3FK)
Putting values in above equation, we get:

Hence, the temperature when the volume and pressure has changed is 274 K
