Ch01 GenChem Spring2015
General Chemistry I
Dr. Judith Albrecht
Introduction
Attendance:
– mandatory for exams and lecture
– absence in the exams leads to fall the class
Goal of this course:
– critical thinking and problem solving by yourself
• responsible for your own learning process
• studying continuously and independently is the key to success – active memorization
– study groups (!!!)
– ask questions

4.Aqueous Reactions and Solution Stoichiometry
5.Thermodynamic
6.Electronic Structure of Atoms
7.Periodic Properties of the Elements
8.Basic Concepts of Chemical Bondings
9.Molecular Geometry and Bonding Theories

– X base and 2 is the exponent. The exponent or power, indicates the number of times that the factor, or base, is multiplied. x2 = x · x and x4 = x · x · x · x xc · xd = xc + d x1 = x x0 = 1
Order Of Operations
1. Calculation within parentheses and other grouping symbols.
2. exponents
3. than multiplication and division; working from left to right in the expression.
4. than addition and subtraction; working from left to right in the expression.
Calculator
• Find the function for log and ln on you calculator. • Remember the log or ln function is the inverse function of the exponential function.
• x = by ,
• if x is 1000, b is 10, what is y
• y = log (x)
• try the inverse function, looking for x
