A sample of chlorine gas occupies a volume of 707 ml at 2.90 atm. What is the new pressure in torr if the volume is compressed t
dolphi86 [110]

Answer:

The new pressure is 3850 torr.  

Explanation:

The relation between volume and pressure is inverse as per Boyle's law. Its mathematical form is given by :

P_1V_1=P_2V_2

Here,

P_1=2.9\ atm

V_1=707\ mL

V_2=0.533\ L

Let P_2 is the new pressure. So using Boyle's law we get :

P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{2.9\times 707}{0.533}\\\\P_2=3846.71\ \text{torr}

or

P_2=3850\ \text{torr}

So, the new pressure is 3850 torr.

Which statement best describes the polarity of CH3Cl? a) The molecule is always polar. b) The molecule is always nonpolar. c) De
Solnce55 [7]

Answer:

a) The molecule is always polar.

Explanation:

The molecule is always polar because of two reasons:

  • all the bonds are polar due to the difference in electronegativity between carbon and hydrogen & carbon and chlorine.

                                              AND IMPORTANTLY

  • The molecule is asymmetrical meaning that the dipoles cannot cancel each other out (like they do in methane or carbon dioxide for example) so the net effect is a polar molecule.
