Answer:
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.
