At what temperature will 0.0705 mol of Cl2 exert a pressure of 900. torr at a volume of 0.750L?
kompoz [17]

Answer:

It will exert the pressure at a temperature of <em><u>153.44 K</u></em>

Explanation:

To answer this question, we shall be using the ideal gas equation;

PV = nRT

Since we are calculating the temperature, it can be made the subject of the formula.

Thus, this can be T = PV/nR

where P is the pressure = 900 torr

V is the volume = 0.75 L

n is the number of moles = 0.0705 mol

R is the molar gas constant = 62.4 L.Torr.k^{-1}.mol^{-1}

Plugging these values into the equation, we have;

T = (900 × 0.75)/(0.0705 × 62.4)

T = 153.44 K

<em><u>I believe that the answer are 3, 4, and possibly 5 </u></em>because the 1st question says, ''Where on earth''. It should have been, ''When on Earth''. The others make sense because the scientist or your teacher can test it. Their has to be evidence to support it.

#1 can't be tested because it was in the last decade (which was 10 years ago). Also, it says in #1 that, Where on Earth had a population decrease.

Hope this helps... :)
