Your chemistry experiment requires you to mix two chemicals in a test tube. To safely observe the chemical reaction you should:

Peer into the test tube from a safe distance

Keep your hand between

Answer 1

between eyes and the opening of the test tube

Keep the end of the test tube pointed away from you

Put your safety glasses on while peering into the test tube

Answer 2

For the first scenario, cool the burn with cold water and tell your instructor. It doesn't matter if it doesn't hurt now, either it will later or it's too severe for you to feel and it's burnt the nerve endings.

For the second scenario, put your safety glasses on. They'll protect your eyes without endangering another part of your body like your hand would.

Answer 3

and also putiing your hand in between would obstruct the view of the test tube and it would be difficult to perform the experiment

Answer 4

washing with soap is not necessary u can just keep your finger under cold water

Answer 5
