Assignment: GRADED: 4.4 Molecular Models for Ethanol Burning

Biology A with Mrs. Mason - Trimester 1
2021-09-21T23:28:16Z

Due: Sep 24, 2021 by 11:59pm

Introduction

There are many different kinds of alcohol. The most common is ethanol, which is the kind of alcohol in alcoholic drinks and in biofuels. Ethanol is a good fuel because it has chemical energy stored in its high energy bonds: C-C and C-H bonds. When ethanol burns, it reacts with Oxygen (O2) in the air to produce carbon dioxide (CO2) and water (H2O). Since CO2 and H2O only have low-energy bonds (C-O and H-O), the chemical energy is released as heat and light.

You will use the molecular models to show how this happens.
