Classily each molecule as having a polar or a nonpolar covalent bond. Then, draw the dipole moment in each molecule. Indicate the partial positive side and the partial
negative side in each molecule.

1) CO2
2) H20
3) CH4
4 Hbr
5) NH3

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
