Chemistry 30 Diploma study guide
Chemistry 30 Diploma · Work through your exam, one topic at a time.
Chemistry 30 Diploma is the provincial Grade 12 diploma examination written by students who have completed Chemistry 30 in Alberta. It is one of the diploma exams in the Grade 12 Diploma Examinations Program, which the province describes as having three main purposes: to certify the level of individual student achievement in selected Grade 12 courses, to ensure that provincewide standards of achievement are maintained, and to report individual and group results. The exam is written at scheduled administrations during the school year, and candidates normally register and write through their own school. Content follows the Chemistry 30 program of studies and is organized into four areas: thermochemical changes; electrochemical changes; chemical changes of organic compounds; and chemical equilibrium with a focus on acid–base systems. Topics on this exam: Thermochemical Changes, Electrochemical Changes, Chemical Changes of Organic Compounds, and Chemical Equilibrium Focusing on Acid-Base Systems. The Chemistry 30 Diploma study guide has 4 sections and about 1,199 words.
01Thermochemical Changes
Thermochemistry tracks energy as heat and enthalpy, ΔH. Define the system and surroundings; q has opposite signs for the two.
309 words, about 2 min02Electrochemical Changes
Electrochemistry links electron transfer to cell potential. Assign oxidation numbers; oxidation is loss of electrons at the anode, and reduction is gain of electrons at the cathode.
281 words, about 1 min03Chemical Changes of Organic Compounds
Organic chemistry questions reward systematic naming and functional-group recognition. Identify the longest carbon chain containing the principal functional group; number to give that group the lowest possible locant, then double/triple bonds, then substituents.
268 words, about 1 min04Chemical Equilibrium Focusing on Acid-Base Systems
Acid-base equilibrium applies dynamic equilibrium and Le Chatelier's principle to proton transfer. Write Ka for HA ⇌ H+ + A- and Kb for B + H2O ⇌ BH+ + OH-.
