Dream Car Stoichiometry Project
By: Abdullah Anwar

Cars greatly impact the environment in many ways. For this project I will be discussing the impact of 5 different types of cars. I have chosen cars from the following categories:

Sports Car, SUV, Truck, Sedan, and a Hybrid. I have chosen a Lamborghini, Lexus, GMC, Cadillac, and a Jaguar. Out of these five my dream car is a Lamborghini.

Amount of mL of gas per year in a Lamborghini
Octane
Introduction
Octane is a gas used in many cars. Octane contains carbon hydrogen. The equation for the combustion of octane is:

C8H18 +O2 -> Co2 + H2O

Balanced equation of Octane:

2C8H18 + 25O2 18H2O + 16CO2

Explanation
Throughout my research I've observed the various impacts these cars have on the world. My dream car had always been a Lamborghini but the right choice would be the Jaguar. Not only is the Jaguar more affordable than my dream car, it is also the most environmentally friendly. In comparison, it has the lowest # of Trees needed to cancel out it's effects. It only requires 187 Trees, which is significantly lower than the 311 needed for a Lamborghini. In addition, it would only fill up about 2055 2 Liter Bottles. This number is much lower than that of the other four vehicles. This car also happens to be a hybrid and therefore better for the environment overall. Above all, I would choose a Jaguar as the best option as it is both environmental friendly, and still a very powerful and attractive car.
