A1.0 m solution of a compound with 2 ionizable groups (pka's = 6.2 and 9.5; 100 ml total) has a ph of 6.8. if a biochemist adds 60 ml of 1.0 m hcl to this solution, the solution will change to ph

How do the energy differences between the higher energy levels of an atom compare with the energy difference between the lower energy level of the atom

Idon’t know how to solve this question

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.)
