C6H12O6 + O2 > CO2 + H2O + energy (673 kcal/mol) (1)
1. Add coefficient to balance reaction (1) in model 1.
2. Does reaction (1) release or absorb energy? Is the reaction
exothermic or exothermic?
3. Reason (1) is a redox reaction. Work with your team to identify
the atom that is reduced and the atom that is oxidized in the
reaction. (Recall that when in a molecular compound, oxygen has an
oxidation number of -2 and hydrogen had...

The dehydration of alcohols Under acidic conditions, alcohols will undergo a dehydration reaction, producing an alkene and water. During the reaction, the hydroxyl group of the alcohol and a hydrogen atom from an adjacent carbon atom are lost. The reaction takes place in three steps, as shown in the diagram. (Figure 1) In the first step, a hydrogen lon bonds to the hydroxyl group of the alcohol. In the second step, the protonated hydroxl group leaves the compound,...
