Answer:
Water and acetone is best by separated through distillation
The correct answer would be option C Acetone and water.
Explanation:
When in a mixture of fluid solution, two liquids are mixed in a form of mixture then these liquid can be separated only one method which is based on the fact. That two different liquids will have two different boiling temperatures which method of separating the Fluids is distillation.
The different liquids that are present in mixture are boiled and the vapours are condensed and the condensed portion is accumulated in another beaker.
Answer:
True
Explanation:
If you look closley at the nucleus, you don't count the neutrons just the prtons which then effect the electrons.
Good luck :)
Answer:
C. 0.20 M Mg ion & 0.40 M Cl ion
Explanation:
MgCl₂ is a ionic salt which is dissociated as this
MgCl₂ → Mg²⁺ + 2Cl⁻
First of all, we have a solution of 200 mL, with [MgCl₂] = 0.6M
Molarity . volume = moles.
0.6 mol/l . 0.2l = 0.12 mol
MgCl₂ → Mg²⁺ + 2Cl⁻
0.12mol 0.12 0.24
This moles are also in 400mL of water, so the new concentration is
[Mg²⁺] = 0.12 m/0.6L = 0.2M
[Cl⁻] = 0.24 m/0.6L = 0.4M
Remember we initially have 200mL and then, we add 400 mL, so we supose aditive volume. (600mL)

Answer is: quark.
Quark is a type of elementary particle and a fundamental constituent of matter.
Quarks form composite hadrons (protons and neutrons). Protons and neutrons are in the nucleus of an atom.
Hadrons include baryons (protons and neutrons) and mesons.
There are six types of quarks: up, down, strange, charm, bottom, and top.
