Question

As we drive an automobile, we don't think about the chemicals consumed and produced. Prepare a list of the principal chemicals consumed and produced during the operation of an automobile. (Assume the automobile is not an electric or hydrogen-powered vehicle. Select all that apply.)

Answer 1

Answer:

a) the chemicals consumed:

1- gasoline

2- oxygen

3- Nitrogen

b) the chemicals produced:

1- carbon dioxide

2- carbon monoxide

3- Nitrogen oxides

4- water

Explanation:

When the car is staring to move the fuel starts  to burn , and to do that it needs to Oxygen to do this chemical process . the car is not an electric or hydrogen-powered vehicle so we are taking here about gasoline fuel (which has many compounds)

and the carbon monoxide is a result of the Incomplete combustion of fuel, so it is a normal chemical produced with carbon dioxide , water and Nitrogen oxides which formed as a result of the chemical reaction between the oxygen and nitrogen  

Answer 2

Answer:

Chemicals consumed: gasoline, oxygen and nitrogen.

Chemicals produced: carbon monoxide, carbon dioxide, water, sulfur oxides, nitrogen oxides, unburned gasoline or fuel and soot.

Explanation:

Hello,

It is widely known that automobiles motion is caused by the gasoline combustion via an applied electric spark leveraging the flammability of the gasoline and the presence of oxygen into the engine. In such a way, we can exemplify such combustion process via the following widespread chemical reaction:

$Gasoline (C_XH_Y)+O_2+Spark-->CO_2+H_2O+Heat$

Whereas the formula of gasoline depends on the average composition of hydrocarbons composing it, typically octane; therefore, if we talk about the chemicals that are consumed and produced during the motion of a car, we ideally set gasoline and oxygen as the mainly consumed reactants and carbon dioxide and heat as the mainly produced species. Nonetheless, gasoline has traces of both sulfur and nitrogen as it comes from the crude oil distillation, in this manner, sulfur and nitrogen oxides could be produced as well during the combustion. In addition, complete combustion seldom happens as not all the oxygen consumes the entire fuel to completion, instead of that, incomplete combustion which produces carbon monoxide, unburned fuel and soot as well. Finally, as the engine uses air as the source of oxygen, it also contains nitrogen which is likely to react with oxygen to produce nitrogen oxides too.

Best regards.
