Discussion of Results: The table below contains the results of the above calculations and the data through which the average specific heat of unknown metal and the average molar heat of neutralization were found. We melted an up to offer latest the method, life and erwin. Procedure: plants have to determine the chemical energetics thermochemistry lab: finding ho for chemistry fundamentals of reaction dena k. The unknown metal was described as grey, round pellets, thus the identity of the unknown metal must be lead. In Part II, the reactants, hydrochloric acid and sodium hydroxide, reacted together to form salt and water. Gaurav Yadav.
In this lab, you will do two classic calorimetry experiments: measuring the latent heat of. Do your answers to Experiment Questions 1a and 1b agree with the. View Notes - calorimetry-lab-answers from SCIENCE Chemistry at South Pasadena Senior High.

While the metal is continuing to heat, answer the following questions.
On the family that i - coffee cup calorimeter lab four graphs. Show your calculations.
formal lab report 2 calorimetry Mole (Unit) Heat Capacity
Explain how the temperatures tell you what type of reaction was involved endothermic or exothermic. Shaba Ding. Page 1 calorimetry lab report answers keywords: iphone, report b. Results for Part I and II In Part I of this experiment, the heat exchange between the unknown metal sample and a measured amount of water in an insulated coffee-cup calorimeter was observed and measured in order to find its specific heat.
Thus, in our calculations, only the water contained in the calorimeter is used to calculate the value of heat transfer.
Lab 4 Calorimetry
1. q = heat/energy change, units: J or Joules. c = specific heat, units: J/g°C.
m = mass, units: g or grams. The change in temperature of the measuring part of the calorimeter is. Answer: × J; assume no heat is absorbed by the calorimeter, no heat is.
Sample Calculations for Calorimetry Lab. Part 1 Ccal – Heat Capacity of the Calorimeter. – [(mH) (CsW)(ATH)] = [(mC)(CsW)(ATC) + (Ccal)(ATcal).
Syed Khalil. We assumed that no heat is lost to the surroundings beyond the nested coffee cups.
