Answer:
A-A and B-B attractive forces contains more energy than AB attractive forces
Explanation:
AA and BB are separated as solutes and solvents in themselves which is an endothermic reaction ΔH<0 while they are free to react to form the product AB that contains lesser amount of energy than the reactants AA and BB of which the excess energy is observed as increased temperature of the solution
ΔH<0 : Exothermic Reaction (negative), because the the products less energetic than reactants.
Dispersing the molecular bonds of the solute AA and the solvent BB solutions by themselves are generally endothermic reactions in as their cohesive forces are broken down to allow them mix, while allowing the free reaction of the molecules is an exothermic reaction as they form the solution component AB which is less energetic accompanied by excess energy as that is observed in heat of the reaction
Answer:
0.263 mol
Explanation:
K2SO4 - potassium sulfate
Molar mass (K2SO4) = 2*39.0983 + 32.065 + 4*15.9994 =
= 174.2592≈174.26 g/mol
45.8 g * 1 mol/174.26 g = 0.263 mol
It is acidic because it has the Carboxylic Acid.
