Answer:

Magnesium Nitride - Mg₃N₂

Calcium Chloride - CaCl₂

Explanation:

Magnesium (Mg) has a charge of +2, Nitrogen (N) has a charge of -3.

Swap the charges and you get Mg₃N₂.

Mg: 2(3) = 6

N: -3(2) = -6

The charges cancel out so the formula is correct.

Calcium (Ca) has a charge of +2, Chlorine has a charge of -1.

Swap the charges and you get CaCl₂.

Ca: 2(1) = 2

Cl: -1(2) = -2

The charges cancel out so the formula is correct.

Hope this helps. :)

zvonat [6]

Answer:

Liquids, because they flow, can occupy whatever shape their container has, so they do not have a fixed shape. Because the particles in liquids are very close together (barely further apart than in solids) liquids do not easily compress, so their volume is fixed. hope that helps love!

Why can't all mixtures be classified as solutions?
natulia [17]

Answer is: Not all mixtures have solutes and solvents.

Solution is homogeneous mixture composed of two or more substances.  

In aqueous solution, solvent is water and solute (for example salt) is a substance dissolved in water.  

Homogeneous solution of salt and water can be separated with heating (evaporating the water).
