Module 2 Lab Discussion Board
During Chapter 3 in the lecture component of the course, we learn about atoms and what they
might look like if we were able to see them. But, how do we know that there are atoms when we
cannot see them? Is it always true that
Module 3 Lab Discussion Board
Observe what happens, and explain why in terms of the chemistry involved. You have done
something similar to this in a previous demonstration, but the concept is slightly different here.
Why can you not light a match in outer
Lab 8 Recrystallization
The first step in purifying a solid is placing an unspecified amount of water into a beaker and
applying a predetermined amount of acetyl salicylic acid (ASA) to the water. Then you must
add an impurity, which in this example, food
Module 4 Lab Discussion Board
Think of an activity you enjoy doing. Research what would be the optimum fuel for that activity.
Provide the nutrient breakdown of what is needed for the activity and how the fuel you have
chosen suits that nutrient profile.
Lab 4 Dilution
When conducting dilution, precise measurements are important to perfect the first time. When performing
a dilution, creating any variance will result in starting over from the beginning, because once a substance
is diluted, you cannot rever
Lab 7 Weighing on an Analytical Balance
Any sort of measurement with chemistry is very important, as it can cause extreme variation if
miscalculated, which can even become dangerous. When using an Analytical Balance, it becomes
somewhat easy to properly m
Module 5 Lab
Distillation is used to separate a specific liquid from either a solid or another liquid. In this example, this
is done by using heat. In this example, we are attempting still ethanol from water. First we place
magnesium shavings into the bot
Module 6 Lab Discussion Board
A Japanese company has developed a chemical that is designed to protect steel from corrosion.
It serves as a protection layer over the steel, and rejuvenates itself over time. This is essential
for the environment for the pur
