Oh now it makes sense. Thank you so much DrBob222 :)
A substance (CD) decomposes into C and D At the temperature of the experiment, 15.0% of CD is decomposed when equilibrium is established. a) if the initial concentration of CD is 0.200mol/L, what are the equilibrium concentrations of CD, C and D? I got 0.17 for CD and I got 0....
"The measure of an angle is 6 more than 3 times the measure of its compliment. i know the quation is X+3x+6 but how do i solve that equation?
Thank you! :)
Consider the reaction: N2O4(g) <--> 2NO2(g) delta H^o =58.576kJ; Keq =0.87 at 55degrees celsius What is the effect of each of these changes upon the concentration of N2O4 at equilibrium? a)increasing the temperature b)increasing the volume c) adding more NO2(g) to the sy...
Thank you DrBob222
Two colourless solutions are mixed in a stoppered flask. as the reaction proceeds, the resulting solution turns red, and a colourless gas is formed. after a few minutes, no more gas is evolved but the red colour remains. what evidence is there that equilibrium has been establi...
the primary visible emissions from mercury are 404.7 nm and 435.8 nm. Calculate the frequencies for these emissions. Calculate the energy of a single photon and of a mole of photons of light with each of these wavelengths.
A ball of mass 0.30 kg is fired with velocity 100 m/s into the barrel of a spring gun of mass 2.2 kg initially at rest on a frictionless surface. The ball sticks in the barrel at the point of maximum compression of the spring. No energy is lost to friction. What fraction of th...
Two toy locomotives approach each other along the same line, and upon collision both stop dead still. One locomotive has three times the speed of the other and the sum of their masses is 4.48 kg. What is the mass of the faster locomotive? What is the mass of the faster locomot...
