### Transcript

• 1. Chapter 10 Test Review
• 2. Chapter 10 Test Review
Bring a calculator and writing utensil to class.
You must be able to operate the calculator that you bring for the test.
A periodic table will be provided.
• 3. Chapter 10 Test Review
Many of the types of questions will be similar to the examples given in-class, in notes and handouts, and on homework assignments.
The chapter 10 test will have all types of questions:
multiple choice
fill in the blank
definition of terms
calculations (temperature conversions; q = mCp∆T; ∆H)
• 4. Chapter 10 Test Review
Terms that you should be able to define include: energy, kinetic energy, potential energy, law of conservation of energy, exothermic process, endothermic process, temperature, heat, convection, conduction, and radiation.
• 5. Chapter 10 Test Review
You must be able to convert temperatures from one scale to another.
The following mathematical formulas will be given:
K = ˚C + 273
˚F = 9/5˚C + 32
˚C = 5/9(˚F – 32)
You must be able to use algebra to manipulate any of the above equations to solve for unknown temperatures.
• 6. Chapter 10 Test Review
The first set of calculations include heat transfer events and the equation q = m Cp ∆T. This equation will be given. You must know what each variable represents and what units quantities must be in when substituting into this equation.
You must know ∆T = Tf – Ti.
A table of specific heat values / Cp will be provided.
You must be able to calculate unknown amounts of heat energy gained / lost in units of joules or kilojoules, values of specific heat, temperature change, or mass.
You must know that 1 kJ = 1000 J.
• 7. Chapter 10 Test Review
The second set of calculations include calculations that relate to heats of reaction and enthalpy - ∆H.
You must be able to identify if a reaction is endothermic / exothermic from given values of ∆H.
You must be able to calculate the amount of heat energy, in kilojoules, absorbed / released in a chemical change starting from moles of reactant/product and grams of reactant/product.
You must know 1 kJ = 1000 J.
