Explanation:
A protective apron or lab coat is important when working with acids because acids break down fabrics and can cause burns if the acids are strong.
- An acid is a substance that interacts with water to produce excess hydroxonium ions in an aqueous solution.
- A strong acid ionizes completely in solution.
- When they come in contact with a fabric, they break them down violently.
- So, if they come in contact with the skin, it causes a violent break down of body tissues.

Answer:
5 mg, 
Explanation:

To rewrite it in scientific notation, we must count by how many digits we have to move the dot on the right - in this case three. So in scientific notation is
If we want to convert into milligrams, we must remind that
1 g = 1000 mg
So we can use the proportion
and we find
