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:
4:Chlorophyll. 6. Photosynthesis 8. Glucose
Explanation:
Answer:
the pH of the solution expresses the concentration of hydrogen ion in the solution. By measuring the pH value of a solution helps us to define the acidity or basicity of the solution. If the pH value in the pH scale is greater than 7 then the solution is basic

<span>A polymer forms because the hydrocarbon joins with itself in a polymerization reaction.
I really hope this helps! :D</span>
The crystal structure of an ionic compound depends on the sizes of cations and anions, as well as the ratio of cations to anions. The ratio of the cations and anions need to be even, otherwise, the crystal won't form.
So the answer would be D, both A and B.
