What is mean by saturated solution and unsaturated solution​
zvonat [6]

•Saturated Solution: A solution in which no more solute can be dissolved in a definite amount of solvent at a given temperature is called a saturated solution.

Example: A soda is a saturated solution of carbon dioxide in water. This is why, when the pressure is released, carbon dioxide gas forms bubbles.

•Unsaturated solution: It is a solution in which more of solute can be dissolved at a given temperature. In this, addition of solute is possible till the solution reaches the point of saturation.

Example: Salt dissolved in water even sugar dissolved in water is an Unsaturated solution if the quantity of dissolved Salt/Sugar is below the saturation point.

Heating 2.40 g of the oxide of metal X (molar mass of X = 55.9 g/mol) in carbon monoxide (CO) yields the pure metal and carbon d
Korolek [52]

Answer:The molecular formula of the oxide of metal be X_2O_3. The balanced equation for the reaction is given by:

X_2O_3+3CO\rightarrow 3CO_2+2X

Explanation:

Let the molecular formula of the oxide of metal be X_2O_y

X_2O_y+yCO\rightarrrow yCO_2+2X

Mass of metal product = 1.68 g

Moles of metal X =\frac{1.68 g}{55.9 g/mol}=0.03005 mol

1 mol of metal oxide produces 2 moles of metal X.

Then 0.03005 moles of metal X will be produced by:

\frac{1}{2}\times 0.03005 mol=0.01502 mol of metal oxide

Mass of 0.01502 mol of metal oxide = 2.40 g (given)

0.01502 mol\times (2\times 55.9 g/mol+y\times 16 g/mol)=2.40 g

y = 2.999 ≈ 3

The molecular formula of the oxide of metal be X_2O_3. The balanced equation for the reaction is given by:

X_2O_3+3CO\rightarrow 3CO_2+2X
