The laser pointer emits light because electrons in the material are excited (by a battery) from their ground state to an upper excited state. when the electrons return to the ground state, they lose the excess energy in the form of 536-nm photons. what is the energy gap between the ground state and excited state in the laser material?

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
