Yоu prepаre а pitcher оf iced teа by mixing the fоllowing together: 400. grams of hot tea at 80°C 300. grams of ice at 0°C Calculate the final temperature of the system when it reaches thermal equilibrium.(Assume the specific heat of the tea is the same as that of pure water = 4.18 J/g°C)(Hint: All of the ice will have melted.) Given ΔH° for the melting of ice:H2O (s) → H2O (l) ΔH° = +6.01 kJ/mol Extra credit question!
