6. What is the wavelength, in nm, associated with a photon of energy of 4.36 x 10-18 J? (4.56 x 101 nm) The numbers in parenthesis is the answer that the teacher gave but I on't know how to get there. Help please!

An observation that requires measurement is called quantitative observable or qualitative

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
