Calculate δgelec if one mole of sodium ions is moved from air for which d1=1.00 into water at t=300k. note that between the temperatures of t=273k and t=373k the dielectric constant of water has the temperature dependence d2=176−0.327(tk) where t is the temperature in kelvin units. note: in the equation for the the dielectric constant of water the notation tk means you enter the numerical value for the temperature into the equation, but without the units k. assume the radius of a sodium ion is r=2.00x10^-10m.

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.
