To obtain pure magnesium chloride, the following separation technique steps are employed:
- add water and filter to dissolve magnesium chloride
- evaporate the water in the filtrate and then crystallize obtain pure magnesium chloride
<h3>What are separation techniques?</h3>
Separation techniques are the techniques employed in the separation of the constituents of a mixture.
To obtain pure magnesium chloride from a mixture of magnesium chloride, magnesium, calcium carbonate, and powdered charcoal, the following steps are employed:
- add water and filter to dissolve magnesium chloride
- evaporate the water in the filtrate and then crystallize obtain pure magnesium chloride
In conclusion, separation techniques are used to separate the constituent of mixtures.

Answer:
4.44 dm³ of SO₂
Solution:
The balance chemical equation is as follow,
CS₂ + 3 O₂ → CO₂ + 2 SO₂
According to equation,
22.4 dm³ (1 mole) CS₂ produces = 44.8 dm³ (2 mole) of SO₂
So,
2.22 dm³ CS₂ will produce = X dm³ of SO₂
Solving for X,
X = (2.22 dm³ × 44.8 dm³) ÷ 22.4 dm³
X = 4.44 dm³ of SO₂
The electron, due to the way an electron orbits the nucleus of an atom.
According to Quantum Mechanics, electrons do not really orbit the nucleus of an atom. In fact, the most tightly bound state, the 1s orbital, has no angular momentum at all. This would be the state with the most "kinetic energy" and yet there is no "orbital" motion at all in this state.
An Ionic bond is the result of transfer of electrons between atoms
13 is the number for it on the periodic table and Group 3 is the correct answer hope this helps.
