An 8.000 gram sample of solid NH.NO, was mixed with a 200.00 mL sample of water in a coffee cup calorimeter. The water was initially at 20.0°C and the final temperature of the resulting solution was recorded as 17.1°C. Calculate the experimental AHcoln (in units of kJ/mol NH.NO:) for the dissolution of NH NO3 (molar mass = 80.04 g/mol). Assume that no heat is lost to the calorimeter or the surroundings. The density of water is 1.00 g/mL and the...

how to do part a, trial 1
Data Analysis Part A. 1. Calculate the specific heat for your metal for each trial. Remember that the heat lost by the metal is equal to the heat gained by the water in the calorimeter and by the calorimeter itself. This can be expressed as - metal (water + Jealorimeter). The specific heats are positive numbers. EXP 8 - Thermochemistry Trial 3 Trial Trial 2 Trial 3 Part C 2 40.408 g 109.536...

Question 2 1 pts Suppose you are investigating the reaction: M(s) + 2 HCl(aq) → MCl2(aq) + H2(g). You weigh out a 0.202 gram piece of metal and combine it with 62.2 mL of 1.00 M HCl in a coffee-cup calorimeter. If the molar mass of the metal is 48.51 g/mol, and you measure that the reaction absorbed 111 J of heat, what is the enthalpy of this reaction in kJ per mole of limiting reactant? Enter your answer...
