Answer:
An atom has a nucleus, made up protons and neutrons, which is surrounded by a cloud of electrons.
Explanation:
An atom is the smallest indivisible part of any element that takes place in a chemical reactions.
These are the fundamental building blocks of every element and even compounds.
- There are three known subatomic particles found within an atom.
- Electrons are the negatively charged particles in an atom
- Protons are the positively charged particles of an atom
- Neutrons do not carry any charges.
Both protons and neutrons are located within the tiny space called nucleus at the center of an atom.
Electrons moves round in orbitals at the spaces outside of the nucleus.
Answer:
8.68 L is the new volume
Explanation:
You use Boyle's law for this.
= first pressure
= second pressure
= first volume
= second volume
Convert pressure from atm to mmHg (use same units):
5.97 x 760 = 4537.2 -> 4.54 x 10³
...maintain 3 significant figures in calculation, and round as needed...
(4.54 x 10³ mmHg)(2.79 L) = (1460 mmHg)()
(4.54 x 10³ mmHg)(2.79 L) / (1460 mmHg) = = 8.68 L
Hope this helps :)
