Apure solvent has a vapor pressure the vapor pressure of a solution. a. equal to b. lower than c. higher than

What is the mass defect of a mole of nuclei with 1.8 x 10^15 j/mol binding energy?

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
