Acids and Bases

MT: Chapter 17.1-3 Test and Review Calculations Lab.
Goal: Apply thermodynamics to chemistry.
Declarative Knowledge Test. 17.1-17.3
Monday
LAB: Measuring the heat changes in a cup of ice to liquid to vapor.
1.) Students Measure a volume of ice (Two-Three Cubes)
2.) Record the temperature every minute until they get the ice to melt then boil.
3.) Students make ____ Calculations.
Given: molar heat of fusion of ice (find in kJ/mol), Specific Heat of Water (4.18 kJ/gram degree Celsius), molar heat of vaporization (find in kilojoules)
How much heat will be required to increase the temperature of the ice to zero degrees. (mCT)
How much heat will be required to melt the ice. (# moles*molar heat of fusion)
How much heat will be required to raise the temperature from 0 degrees celsius to 100 degrees celsius? (mCT)
How much heat will be required to boil all the water off?
Tuesday: Guided Reading of next chapter.
