Webmolecules of Hydrogen gas to produce 1 molecule of methanol. 1 mole of Carbon monoxide reacts with 2 moles of Hydrogen gas to produce 1 mole of methanol. From the coefficients in the balanced equation, we can determine the mole ratios of the substances involved in the chemical reaction. CO : H 2 = 1 : 2 or CO : CH 3 OH = 1 : 1 or 2 mol H 2 WebOne molecule below is extremely polar while the other is nonpolar. Use the same process as above (12.2a) to determine which is polar and why? 8. 12.2 a. Most molecules with only C and H are nonpolar. However, the following molecule is extremely polar because the central pi electrons are actually pulled into either the 5-membered or 3-membered ring.
