Useful equations and constants: heat lost/gained = (Volume (Density)(AT)(specific heat capacity) (heat lost by hot water) - Cheat gained by cold water) calorimeter constant = Density co = 1.00 g/mL Specific heat capacity (water) - 4.184 J/g °C 1. What is thermochemistry? (2 pts) 2. A student adds 5.00 mL of cold water to 5.00 mL of hot water in a test tube surrounded by a Styrofoam installation (ie, calorimeter). The initial temperature of the cold water was 15.26 °C,...

Compound Δ Hrxn (kJ/mol) NH4NO3 + 25.7 KCl + 17.2 NaOH -44.5 KOH -57.6 You are given 6.9 grams of an unknown salt. You dissolve it in 56.5 mL of water. As the salt dissolves, the temperature of the solution changes from an initial temperature of 28.9°C to a final temperature of 22.9°C. Based on the chart of ΔH values and the temperature change, you can determine which salt you have. What is the temperature change? Δ T = o C...

Lab 9 Heat of Reaction
OBJECTIVE:
To experimentally determine the heat of reaction for two
exothermic reactions.
DISCUSSION:
The heat given off or gained in a reaction is called the heat
of reaction (∆?????????).
A reaction that releases heat is known as an exothermic
reaction; an endothermic reaction
is one that absorbs heat.
The heat of the reaction corresponds to one mole of the
reactant and is expressed in
kilocalories per mole of reactant or in kilojoules per mole of...

In this experiment, you will determine and compare the quantity of heat energy released in three exothermic chemical reactions through application of Hess’s law. Reaction 1: NaOH(s) → Na+(aq) + OH-(aq) + x1 kJ Reaction 2: NaOH(s) + HCl(aq) → H2O(l) + Na+(aq) + OH-(aq) + x2 kJ Reaction 3: NaOH(aq) + HCl(aq) → H2O(l) + Na+(aq) + OH-(aq) + x3 kJ In order to accurately measure the heat released in each reaction, we will be using a calorimeter. As...
