A supersonic jet is flying west at one-third of its maximum speed. The jet's top speed is 4,500 kilometres per hour. If the jet's velocity remains constant, how much time will it take the jet to fly 3,000 kilometres?

Write the complete balanced equation for the reaction between lead (iv) oxide (pbo2) and water (h2o).

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
