Calculate the mass of emitted into the atmosphere upon accelerating the from 0.0 to 67.0 . Assume that the required energy comes from the combustion of octane with efficiency. Use to calculate the kinetic energy required for the acceleration.
What is w when a gas is compressed from 38.3 L to 28.8 L using a constant external pressure of 745 mmHg? (Remember to include a "+" or "-" sign as appropriate.)
Is a first order rate constant of 3.14x10^-4 1/s at room temperature, if you currently have a 2.5 M N2O5 how long will it take for 65% of N2O react?
A very crude model of the buckminsterfullerene molecule (C60) is to treat it as a collection of electrons in a cube with sides of length equal to the mean diameter of the molecule (0.7nm)
The initial concentrations of four species in an equilibrium are [Cl2] = 1.40 M, [HCl] = 0.100 M, [O2] = 0.300 M and [H2O] = 0.500 M. Is the reaction at equilbrium? If not in what direction must the reaaction shift for the equilibrium to be reache..
