Do you think you could go a week
without causing any chemical reactions? Explain
why or why not, providing examples where
appropriate. Do not count reactions that take
place inside your body.

The answer to your question is No

Explanation:

I think it is impossible to go a week without causing any chemical reaction. For example, if a drive my car or motorcycle, I am burning fuel and that is a combustion reaction.

Also, I want to cook, all this process involves a lot of chemical reactions among the components of food and maybe water.

If I take a shower or wash my hands, between the soap and the microbes occur are some chemical reactions that help to remove these organisms.

Also, when I wash my clothes something similar happens.  

These are some examples of the chemical reactions that happen daily but I think there are a lot more.
