Explain the roles of subscripts and coefficients in chemical equations.
Balance a chemical equation when given the unbalanced equation.
Explain the role of the Law of Conservation of Mass in
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
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
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
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
5.4: Review Questions How many molecules are present in the
following quantities? 1) 0.250 mol H2O 2) 0.0045 mol Al2(CO3)3
How many moles are present in the following quantities? 3) 1.0x102
for the reaction. Cu(s) + AgNO3(aq) Cu(NO3)2(aq) + Ag(s) The
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
