word equation for this reaction might read something like "solid
copper reacts with an aqueous solution of silver nitrate to produce a
solution of copper (II) nitrate with solid silver". In orde

Collision Theory The collision theory provides us with the ability to
predict what conditions are necessary for a successful reaction to take
place. These conditions include: 1. The particles must collide with
each other. 2. The particles must collide wit
Very large and very small numbers in science are
expressed in scientific notation.
Scientific notation: a shorthand method of writing very
large and very small numbers in terms of a decimal number between 1
and 10 multiplied by 1
increase in temperature there is an increase in the number of
collisions. Increasing the concentration of a reactant increases the
frequency of collisions between reactants and will, therefore, increase
the reaction rate.
Increasing the surface area of a
energy barrier and at room temperature many more collisions will be
occurring. This allows for the milk to spoil in a fairly short amount of
time. This is also the reason why most fruits and vegetables ripen in
the summer when the temperature is much warm
