Explanation:
Chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. ... The fundamental principle of the science of chemistry is that the atoms of different elements can combine with one another to form chemical compounds.
A.
This is because BaSO₄ has the lowest solubility product out of all the substances.
<u>Answer:</u> The temperature in degree Celsius is 301.31°C
<u>Explanation:</u>
To calculate the temperature, we use the equation given by ideal gas, which is:

P = pressure of the gas = 670 torr = 0.882 atm (Conversion factor: 1 atm = 760 torr)
V = volume of gas = 42.5 L
n = number of moles of gas = 0.795 mol
R = Gas constant = 
T = temperature of gas
Putting values in above equation, we get:

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:


Hence, the temperature in degree Celsius is 301.31°C
