(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

is a shorter way to show chemical reactions, using symbols instead of words
is a material that releases energy when it burns
the minimum amount of energy needed to start a chemical reaction
the rate of a chemical reaction is controlled by what?
changing factors such as concentration, temp, SA, and using catalysts and inhibitors
a solid that forms from solution during a chemical reaction
a reaction that releases energy in the form of heat
a rapid reaction between oxygen and a substance called a fuel
how are chemical reactions classified?
synthesis, decomposition, replacement
are the materials you have at the beginning of a reaction
a material used to decrease the rate of a reaction is called an ------
show the ratio of the atoms of different elements in a formula
are color change, production of a gas or a precipitate, a change of temp, or a change in the properties of a substance
the amount of one material in a given amount of another material
is when in a reaction, matter isn't created or destroyed
a reaction that takes energy or heat from the solution
are reactions between 2 atoms that make a new substance after they react to each other
when an element replaces another in a compound, or when 2 elements in different compounds trade places
this process breaks down compounds into simpler products
