A photon travels with a frequency of 8.57 x 10'4 Hz. a. Find the wavelength of this photon in nm? b. Find the energy contained by a single photon. Put your answer in kJ.

0.09 moles of sodium sulfate in 12 ml of solution

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
