What should be done if a chemical is poured from an original container into another container not intended for immediate use?

Answers

Answer:

Label

Explanation:

You need to search if the chemical need a glass or plastic container. Also if the chemical need to be in a clear or dark container that can protect it from light. Also if need to be a certain temperature, for example, if need to be in the fridge or can be at room temperature.

Answers

1) Xenon
2) Berylium
3) Aluminium (Assuming 3p = 3rd Period)
4) Tungsten
5) Bromine
6) Xenon again
7) Indium I think
8) Strontium
9) Titanium
10) Oxygen
11) I don't understand that at all XD

What orbits the nucleus of an atom?

Answers

Electrons orbit the nucleus of an atom. They are very small, in fact they are 1/2000 of an amu. Electrons are negative while the inside of an atom includes the positive protons and neutral neutrons. :D
Electrons. They are found in the orbitals outside the nucleus.
