Stay under the shower until the shirt has been completely rinsed. B. Remove your shirt and any other clothing that were in contact with the chemical. C. Stay under the shower for at least 15 minutes.

Remove your shirt and any other clothing that were in contact with the chemical

Explanation:

A hazardous chemical has the capacity to cause damage to the body when it comes in contact with the skin. Many hazardous chemicals are capable of being absorbed into the body via the skin.

Once your lab coat is already doused with the chemical and it has started soaking into you clothing, you must remove your lab coat, shirt and all clothing that were in contact with the hazardous chemical as a safety measure to avoid absorption of the chemical into the body via the skin. Some of these chemicals also cause damages directly to the skin and this must be avoided.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
