Chem 122- 1-First we will complete the problem from 58 in pairs from yesterday and you were assigned the assignment on thermochemical equations. It is due tomorrow. 2-We will complete calorimeter theory and then do a slightly new calculation with a bomb calorimeter. Please do #5(bomb calorimeter calculation) 3-You have a quiz on Hess's Law-1 question tomorrow 4-If time permits.. More work with reaction calculations with heat of reaction and an equation is provided Please do 11 a and b for hwk it is like 14 and 15 from the text Test next tuesday on Ch 17 and energy calculations.. Calorimeter calculation: Need more practice? Extra Practise: A. A chemistry student dissolves 4.51 grams of sodium hydroxide in 100.0 mL of water at 19.5°C (in a calorimeter cup). As the sodium hydroxide dissolves, the temperature of the surrounding water increases to 31.7°C. Determine the heat of solution of the sodium hydroxide in J/mol. B. A 2.50 g sample of zinc is heated, then placed in a calorimeter containing 65.0 g of water. Temperature of water increases from 20.00 Celsius to 22.50 Celsius. The specific heat of the zinc is 0.390 J/g oC. What was the initial temperature of the zinc metal samples.(we are going to assume that the final temp of the zinc and the water is the same. C. A 5.23 g sample of coal(assume pure carbon) is placed in a bomb calorimeter that has a specific heat of 4.53 kJ/oC. If the temperature changes from 21oC to 28oC, find the Hc for the coal.

 * Thursday Feb 18-** Now Friday Feb 19................Chem 122 Test on Tuesday of next week... .................................

Chem 122 Period 1 1-I went over the last type of calculation where energy produced is used to heat something up. Here is the example 13.(You will add 13 to your page).
 * 1) 13 What amount ( mass) of methane undergoing complete combustion is required to heat 100.0 L of water from 5 degrees celsius to 70 degrees celsius?

Here is another question like #13 to try What mass of propane must be burned to heat 2.50 L of water from 10 degrees Celsius to 800 degrees Celsius?

2- there is an outline under the test review link that is like the Study guide at the end of your chapter. There are also some practise problems linked as a document too. Please remember that there are several practise questions at the end of the chapter. We will do some more group review to practise certain key types of questions for the test. .
