Answer:
92.6 kJ.
Explanation:
<em>∵ ΔG°rxn = - nFE°cell,</em>
Where, ΔG°rxn is the standard free energy change (J).
n is the no. of electrons in the reaction (n =2).
F is Faraday constant (C/mol) (F = 96500 C/mol).
E°cell is the standard cell potential (E°cell = - 0.48 V).
<em>∴ ΔG°rxn = - nFE°cell </em>= - (2)(96500 C/mol)(- 0.48 V) = <em>92640 J = 92.64 kJ.</em>
Explanation:
a colloid is a nonuniform mixture of a solute and a solvent in which the particles are permanently suspended.
solution is a uniform mixture of a solute and a solvent.
suspension is a nonuniform mixture of a solute and a solvent in which the particles are temporary suspended

Answer:
Concentration
Explanation:
Concentration is measure of the quantity of solute present in a given amount of solvent. Concentration can be measured in mol/dm³, g/m³ and other forms like molality, parts per million.
Concentration in mol/dm³(molarity) is a measure of the amount of moles of solute present in 1 dm³ of solvent while concentration in g/dm³ is the number of grams of solute present in 1 dm³ of solvent. These units of concentration can be converted to the other unit by using simple conversion methods.
molality refers to the amount of solute in 1 kg of solvent, while ppm is basically used for very dilute solutions.
