Answer 1

We correcting your As per Problem given Information - Solution , mole of the = mass of Hecat solution (m) = capacity (Cp) = 0.075 mole 100 gm 4.18 I AT = Tfinal - Tinties = (30.6 - 20.3) ac AT - 10.3 oC = in cp AT - = 100x 4.18 x 10.3 =-43.5.4 I = 4305.4 J. Head

(AH) Neletralization = -a mole & rice = (-4305 •4 J) x (1 k I J 0.075 lao0J) - - 57.40 kJ/mole dice AH Explanition. is ove than Reaction is Exothermic It is Exothermic reaction, Meat released during Neutralization (AH <ol and temperature of solution is raised
your answer is almost correct except sign significance of deltaT
