in an experiment a student mixes a 50.0 ml sample of 0.100 m agno₃ (aq) with a 50.0 ml sample of 0.100 m nacl(aq) at 20.0°c in a coffee-cup calorimeter. which of the following is the enthalpy change of the precipitation reaction represented above if the final temperature of the mixture is 21.0°c? (assume that the total mass of the mixture is 100. g and that the specific heat capacity of the mixture is 4.2 j/(g.° (a) -84 kj/mol, (b) -0.42 kj/mol (c) 0.42 kj/molu (d) 84 kj/molpx
