It's useful to them because they know and can predict on how it will react within certain situations. Knowing this, they can develop ways to engage substances or why they're important in certain situations.
Answer:
unsaturated
Explanation:
All solutions have a definite capacity of dissolving solute in it.
Unsaturated solutions are the solutions which contain less amount of solute than the maximum capacity of dissolving the solute. If more amount of solute is added in such a way a point is reached where addition of more solute cannot be dissolved. The solution is known as saturated solution.
Amount dissolved > Maximum solubility limit, the solution is saturated.
Amount dissolved < Maximum solubility limit, the solution is unsaturated.
If the amount of the salt exceeds the solubility limit, then the solution is saturated solution. If it is less than the limit given, then it is unsaturated solution.
The solubility = 0.667 grams per liter
Amount dissolved = 0.502 grams per liter
Since,
Amount dissolved < Maximum solubility limit, the solution is unsaturated.
From the stoichiometry of the reaction, the percentage yiled of the copper is 89.6%
<h3>What is reaction equation?</h3>
The reaction equation here is given as; Fe(s) + CuSO4 (aq) ----->FeSO4(aq) + Cu(s)
Number of moles of Fe = 0.9845 g/56 g/mol = 0.018 moles. Since the reaction is 1:1, this is also the number of moles of Cu formed.
Theoretical yiled of Cu = 0.018 moles * 63.5 g/mol = 1.143 g
Percentage yiled = 1.024 g/1.143 g * 100/1 = 89.6%
If 1 mole of Fe contains 6.02 * 10^23 molecules
0.018 moles of Fe contains 0.018 moles * 6.02 * 10^23 molecules/1 mole = 1.1 * 10^22 molecules.
Number of moles of AgNO3 = 1.35 g/170 g/mol = 0.0079 moles
Molarity of the solution = 0.0079 moles/250 * 10^-3 L = 0.0032 M
Hence; 0.0032 M * V1 = 100 mL * 0.01 M
V1 = 312.5 mL
