D. Pentane. Pentane has 5 Carbon and 12 Hydrogen, like the molecule shown.
The difference is due to the fact that calcium chloride has stronger intermolecular forces than water.
Gay-Lussacs law states that pressure is directly proportional to temperature at constant volume.
in this case the volumes of the 2 containers remain the same therefore volume is constant.
P/ T = k
where P - pressure, T - temperature and k - constant
when temperature decreases the pressure too decreases and vice versa.
if temperature of one container is lowered the pressure also reduces.
since one containers temperature is lowered the pressure in that container reduces.
answer is when temperature is lowered, pressure too is lowered.
Answer:
D. 60.3 kilometers per hour
Explanation:
Hello,
In this case, we first compute the miles in kilometres:
Then the minutes in hours:
Finally, the velocity:
Thus, answer is D. 60.3 kilometers per hour
Best regards.
