Answer:
There are 1.205x10²³ particles in 0.2 moles.
Explanation:
In order to <u>convert from moles to number of particles</u> we need to use <em>Avogadro's number</em>, which states the number of particles contained in 1 mol:
- 0.2 mol * 6.023x10²³ particles /mol = 1.205x10²³ particles
Thus, there are 1.205x10²³ particles in 0.2 moles.
The answer is going to be 1986000. hope that helped
Answer:
Alkali and alkaline-earth cations are energetically stable with an empty valence shell. Atoms of alkali and alkaline-earth elements achieve octets after losing one (alkali) or two (alkaline-earth) electrons such that they minimize the potential energy of the system.
This <u>heterogeneous </u>mixture is a suspension of oil and vinegar
A mixture is a physical combination of two or more substances and each of these substances preserves its identity and form in the mixture.
A homogeneous mixture is a mixture in which is one substance thoroughly dissolves in the other and its composition is uniform throughout the solution. e.g salt and water.
A heterogeneous mixture is one in the two substances form two layers and their composition varies throughout the mixture.
From the given information, the mixture of oil and vinegar is an example of a heterogeneous mixture.
