Ch. 5 & 11 conversion factors & light test [65 points] honors Chem
For problems involving calculations, show your work in an organized manner, include any relevant equation (or formula and conversion factor(s)), put the proper units in your calculations / answer, and have the proper number of significant figures in your answer. Your answers have to start and end of the same side of a paper, to be done in sequence, and clearly identify the question done; otherwise, you will lose points. Attach this sheet to the front of your exam.
Academic Honesty: The answers on this test are my own and I am using only the allowed set of notes as described in the syllabus. I have not discussed the test questions with anyone before or during the test nor have I seen the test questions prior to the exam. If you violate any of the preceding items or do not sign, your semester grade is a F.
