In 1869, Mendeleev noticed that certain groups of elements had
When the elements are arranged in order of increasing mass,
certain sets of properties r
Gas moves in a straight line
Gases have no volume on their own
Gases the higher the temperature, the higher the energy the gases have
Gases do not like to interact with one another, if they do they bounce off, the energy is
transferred from one part

1. Complete and balance the following redox equation using the smallest whole-number
coefficients. What is the coefficient of Sn in the balanced equation?
Sn + HNO3 SnO2 + NO2 + H2O (acidic solution)
The acid dissociation constant (Ka) is the measure of
the strength of an acid in solution.
Liquid water is not included in the equilibrium
What is the pH of a 0.10 M solution?
Chemical kinetics is the study of reaction rates,
including how reaction rates change with varying
conditions and which molecular events occur
during the overall reaction.
We know it is possible to determine whether
Redox reactions are those involving the oxidation
and reduction of species.
Oxidation and reduction must occur together. They
cannot exist alone.
Fe0 + Cu2+ Fe2+ + Cu0
Reduced: Copper ga
Chemical reactions often seem to stop before they are
Actually, such reactions are reversible. That is, the
original reactants form products, but then the
products react with themselves to give back the
