Welcome To Mr Bonnell's 4U Chemistry Class.

Before we get started there are a few things you should review:

1) sig figs - these are very important in chemistry calculations - you must pay attention to them as you will lose 1/2 a communication marks each time you get them wrong - pay close attention to the rules for rounding (odd - even rule) and for multiplying and dividing

[|Sig Fig Review]

2) equation manipulation - the link below is an excellent site for a review of the rules

[|Rearranging and Solving Equations] [|More Equations]

3) quadratic equations

[|Quadratic Equation Practice] 4) factor label method - this is the easiest way to solve difficult equations - pay very close attention to your units and it is almost impossible to get the math wrong - in 1st year chem classes at university there are 2 groups of people (those that use factor label and those that are not very successful in the course)



Here is a powerpoint presentation going over factor label problems.
