If it takes 1130 kJ of heat to boil 0.500 kg of water, what is the enthalpy of vaporization or
water?
0.5 kJ/kg
0 1130 kJ/kg
o 2260 kJ/kg
O 4520 kJ/kg

well off of my head we know that the perfume bottle is most likely opened, or broken. i can also tell it is moving at low and high concentration because it is covering the other side of the room. what we can obtain from this information is it explains why the odor can be detected at the other side of the room.

h let me think

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24
