If you find a chemical in the lab and are unsure of its identity, what is the best way to find out what it
is?

C. read the label on the container

Explanation:

What information is found in an SDS? Check all that apply.

A. the identification of the chemical

C. the chemical and physical properties of the substance

D. the first-aid measures to take if an accident occurs involving the chemical

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
