Biofuels, Acidic and Basic Balancing Chem Test

what does incomplete combustion yield

CO2 + H2O + CO + C (limited O2)

What do metals yield

Ionic oxides

Ex: 2Mg + O2 -→ 2MgO

What is the difference between alcohols and alkanes

Alcohols release less energy than alkanes

What does increased chain length cause

Increased delta HC (kj/mol)

decreased specific energy (MJ/kg)

What are the products of the oil industry (crude oil)?

natural gas, fuel oil, and gasoline (fuel)

What is fractional distillation?

how we separate crude oil

What does fractional distillation rely on?

boiling point

What are the advantages of biofuels?

Carbon neutral, fewer toxic gases, and can still undergo incomplete combustion

what does complete combustion yield

CO2 + H2O

What do nonmetals yield

oxides

Ex: S + O2 → SO2

hydrogen

H2

What is the half reaction of hydrogen?

H2 → 2H+ + 2e-

methanol

CH3OH

what is the half reaction for methanol

CH3OH + H2O → CO2 + xe-
