Question

A student performs an experiment in which she heats a nonflammable
chemical over a gas burner. Which would be a poor laboratory practice during
this experiment?

Answer 1

Answer:

A: Eating a sandwich

Explanation:

During labs eating is a big no. Some food can catch on fire, or be contaminated or breed germs that can affect the experiment. Wearing googles is a good idea and tying back hair is a must when using fire. The work area should always be clean so A is the answer

Answer 2

The answer is A.
This is because you should not eat in a lab. It can cause many different issues with your experiment, including changing your variables.
