Explanation:
Let us proceed with a reaction
A(aq)+B(aq) C(aq) + D(g)
Taking A, B and C are in aqueous solution. D being a gas. The reaction is carried out in a close vessel. As reaction proceeds, A and B react to give C and D. As the concentration of C and D increases, they react to give back A and B. Now suppose the reaction is carried out in a open vessel so that the gas D can escape in the atmosphere. So the gas D is no longer available to react with C. So reverse reaction will not occur. The forward reaction is forced to reach 100 %
Let us take another example.
A(aq)+B(aq) C(aq) + D(aq)
Here, D is a volatile liquid. As soon as D is formed, it is removed by distillation. So D is no longer available to react with C. So reverse reaction will not occur. The forward reaction is forced to reach 100 %
Answer:
2480$
Explanation:
2000$*(3%=0.03)=60$
multiply by 8 = 480$
then by adding it to 2000 = 2480$
This equation shows how HF, hydrofluoric acid behaves in water.
HF (aq) ----> H+ (aq) + F- (aq). In water acids will dissociate into positive cations and negative anions. The strength or weakness of an acid depends on its ability to dissociate in water. Substances that dissociate completely are strong acids while partial dissociation indicates a weak acid. HF is considered to be a weak acid because it does not completely dissociates in water. There is instead an equilibrium between HF molecules and the dissociates.
The correct answer to this question is letter "A. homogeneous mixture." The following characteristics describe the type of mixture, which is a homogeneous mixture. The substance is mixed uniformly throughout and each part of <span>the substance contains the same ratio of materials with the same properties</span>
