Which of the following molecules would you expect to have a dipole moment of zero?

Mashcka [7]

Answer:

CCl2=CCl2

Explanation:

Recall that the individual dipole moments in a symmetrical molecule cancel out each other thereby making the overall molecule to be non polar.

CCl2=CCl2 contain individual polar bonds but the molecule is highly symmetrical thus its dipole cancel out and the molecule has no overall dipole moment, hence CCl2=CCl2 has a dipole moment of zero .

above shows a balloon full of gas which has a volume of 120.0ml at 300.0k assuming pressure remains constant , what is the voume

trasher [3.6K]

128 ml is the voume of the balloon if the temperature of the gas increases to 320.0k.

Explanation:

given that:

T1 (initial temperature) = 300K

V1 ( initial volume) = 120ml

T2 (final temperature) = 320 K

V2 (final volume) = ?

Pressure remained constant throughout the process.

From the equation

$\frac{P1V1}{T1}$ = $\frac{P2V2}{T2}$

Since pressure is constant the equation will be:

$\frac{V1}{T1}$ = $\frac{V2}{T2}$

V2 = $\frac{V1 X T2}{T1}$

Putting the values in the above formula:

V2 = $\frac{120 X 320}{300}$

= 128 ml

128 ml is the volume of the gas if temperature increases from 3OO K to 320k
