Xample: A solution of NaCl was prepared by dissolving 5.0 g NaCl (molar mass = 58.5g/mol) in
100.0 g of water (molar mass = 18g/mol). What is the
vapor pressure of pure water if the vapor pressure of
this solution was 19.6 torr.​

It takes 945.kj/mol to break a nitrogen-nitrogen triple bond. calculate the maximum wavelength of light for which a nitrogen-nitrogen triple bond could be broken by absorbing a single photon.

Drag each label to the correct location on the chart. classify each reaction as endothermic or exothermic.

Alidded glass container is filled with a colored gas. after a period of time, it is observed that the gas is uniformly spread throughout the box and that the movement has slowed considerably. next, a warm iron plate is carefully placed under the box. why is there resumed movement of the gas in the container?
