A gas that exerts a pressure of 15.6 psi in a container with a volume of
L will exert a pressure of
25.43 psi when transferred to a
container with a volume of 1.895 L.

3.09L

Explanation:

according to Boyles law, P1V1=P2V2

25.43(1.895)=15.6V2

48.19= 15.6V2

48.19÷15.6=V2

3.09L=V2

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
