The videos for introduction to kinetics and rate of reaction on Khan Academy were both extremely
useful. The most useful thing that I learned from these videos was how to determine the reaction order.
Reaction order is determined by the basic equation for
3) What happens to a freshwater plant in seawater and a sea water plant in freshwater
Freshwater plant cells have water drained through a process called crenation and shrivel up and
Seawater plant cells have water pumped into them through a process c
1) The following data were obtained for the reaction of methane with oxygen:
CH4(g) + 2 O2(g) -> CO2(g) + 2 H2O(l)
a) How many moles of CO2 are produced for each mole of
Week 2 Summary
What I was able to learn from the videos was very useful. First, I learned how intermolecular forces have
a big impact on the temperature and pressure required in order to obtain a phase shift. The best
The videos for this week were very informative. The first of this weeks videos was a basic explanation of
reactions in equilibrium. The main point of the video was to show how a reaction is not normally just a
one-way street. In general, reactions proceed

An orbital is an area around the nucleus of an atom where there is a probability of finding
an electron. If we assume that an atom is neutral, then they will have the same number of
electrons as protons. The
Introduction to Chemistry : Week 1 Videos
Pure substances that have specific properties at certain temperatures are called
elements. The elements are all organized on the periodic table. The smallest unit of an element
is an atom.
Week 4 Summaries
This week the videos covered types of chemical bonds which are ionic, covalent, polar
covalent and metallic. All bonds are atoms sticking together because they are sharing electrons.
An ionic bond creates a cati
Week 5 Summaries
This weeks videos discussed the mole, molarity, molality, osmolarity, osmolality and
tonicity. The mole is simply a name referring to a number. One mole is equal to 6.022 times 1023.
