Ineed with module 6 notes as well i will give out 50 points
module 6:
chemical reactions
the substances in a chemical reaction, before the reaction takes place are called?
the substances that form as a result of the chemical reaction are called?
signs that a chemical reaction has taken place and an example of each:
example: alkaseltzer think about the bubbles
1.

3.
the language of chemistry:
chemical reactions can be represented by
balancing equations:
define the following terms;
coefficients:
conservation of mass:
a chemical equation that is written incompletely or incorrectly indicating the there are not the same number of each type of atom on both sides of the equation is called a(n) equation.
in order to balance one of these you can change the in front of the molecules but not the which would result in changing the compound. (not cool! )

combustion reactions
what happens in a combustion reaction?
an example of a combustion reaction would be….
more reaction types:
describe the following reactions;
a + b → ab synthesis:
ab → a + b decomposition:
a + bc → ac + b single replacement:
ac + bd → ad + bc double replacement:
acid and base reactions:
hcl + naoh → nacl + h2o
acid + base → salt + water
in an acid–base reaction, an acid and a base react to form?
oxidation-reduction reactions:
a second way to classify reactions is by what happens to electrons during the reaction. using this method, there are only two main types of chemical reactions: reactions and reactions.
6.04
“before a chemical reaction can occur, the reactant molecules must collide with a certain amount of energy and with a certain orientation.”
record the speed of the reaction rate for the number of players present in the activity:
3 __
6 __
10 __
does every collision cause a reaction?
why tab:
the temperature of a solution is a measure of the average the molecules in the solution. the higher the temperature, the faster the molecules are moving. what effect do you think temperature will have on the speed of the bicarbonate reaction?
6.05
the number of vary between atoms of a given element. remember that an atom of an element with a specific number of neutrons is called an that element.
