What's the ratio? an acid with a pka of 8.0 is present in a solution with a ph of 6.0. what is the ratio of the protonated to the deprotonated form of the acid?

Iam in desperate need of with this !

If i can still dissolve more sugar into the solution at a certain temperature what would i call that solution

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
