Answer : The equilibrium concentration of
is, 0.50 M
Explanation : Given,
Initial moles of
= 0.65 mole
Volume of solution = 1.0 L
Moles of
at equilibrium = 0.15 mole
The balanced equilibrium reaction will be,

Initial moles 0.65 0 0
At eqm. (0.65-x) x x
Moles of
at equilibrium = x = 0.15 mole
Moles of
at equilibrium = x = 0.15 mole
Moles of
at equilibrium = (0.65-x) = (0.65-0.15) = 0.50 mole
Now we have to calculate the concentration of
at equilibrium.
Formula used : 



Therefore, the equilibrium concentration of
is, 0.50 M
Answer:
The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7
is basic.

Explanation:
I makes sense to pick option 2
Sugar is the solute since it is the thing that is being dissolved.
And the water is the solvent since it is the thing that contains the solute.
