Using the GOES X-ray Flux plot data (1.0 -8.0A), what was the peak x-ray emission level (in watts m-2) for the time period shown? On what date did it occur?

Define the kinetic molecular theory

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.

Calculate the percent composition by mass of each element in al(oh)3. use at least three significant figures.
