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 short answer 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.
