Chemistry Quizzes & Trivia

Chemistry. Includes compounds, elements, formulas, ionic vs covlent, four reaction types, balancing equations (law of conservation of matter), reaction rates, acids, and bases! So I didn't know how to study for our test, so I made a quiz! sorry if i spelled something wrong, which makes you get it wrong. = ( This isn't very good, and may not have everything you need in order to study for the upcoming test, but i tried. Good luck, and if there's any suggestions, feel free to tell me! P. S. Sorry its so long, it took so long to make!
