Portage Chemistry 103 Module 1 Exam Study 1.1 EXPONENTIAL NUMBERS - The speed of light is 186,000 miles per second. This is 1.86 x 105 (in exponential form) The diameter of an E. coli cell is 0. meters = 8.0 x 10-7 (in exponential form) . A number larger than one will have a positive exponent. Move the decimal point nine places to the left to give 4.95 x 109 0. A number smaller than one will have a negative exponent. Move the decimal point 13 places to the right to give 5.6 x 10-13 ...

3.1: THERMOCHEMISTRY - CORRECT ANSWERS Thermodynamics is the study of the relationship between heat and other forms of energy, particularly mechanical work. Thermochemistry is the part of thermodynamics that deals with the quantity of heat given off or absorbed during a chemical reaction. The quantity of heat given off or absorbed during a physical change or temperature change can also be studied, and we will refer to this process as calorimetry. System - CORRECT ANSWERS the object (or subs...

Portage Chemistry 103 Module 2 Exam Study 2.1: MOLECULAR WEIGHT Correct Answer: A compound is made up of two or more elements combined in a definite ratio that is represented by a molecular formula. Each of these elements has a certain atomic weight, which can be found in the periodic table. The sum of the atomic weights of the atoms in the molecular formula is called the formula weight or molecular weight or formula mass. Ca3(PO4)2 Correct Answer: calcium phosphate Molecular Weight = ...
