Reaction Types
what are the 5 reaction types
Synthesis
decomposition
combustion
double replacement
single replacement
What law does Balancing equations satisfy?
The law of conservation of mass
solid potassium chlorate decomposes into a solid potassium chloride and oxygen gas.
on Callie paper AGAIN
how do you balance chemical equations
write correct formulas and change coefficients
what are the reactants of a synthesis reaction
2 elements
_NH3 + _H2SO4 ---> _(NH4)2SO4

Aqueous magnesium sulfate & aqueous sodium hydroxide produce solid magnesium hydroxide and aqueous sodium sulfate
once again on Callies paper
what are the diatomic elements
H N O F Cl Br I
what is AB - A + B an example of
decomposition
Balance
_Al + _Cl2 --- _AlCl3

PRODUCT PREDICTION
CuBr2 + I2 --->
CuI2 +. Br2
what are the symbols that go behind coumpounds
(x)
states if matter (s) (L) (G) (AQ)
What are the products of combustion
CO2 + H2O
_N2 + _O2 + _H2O ---> _HNO3

H3PO4(aq) + NaCl(aq)
on Callies papaer again
what do net ionic equations represent
only the species involved in the chemical change
Give an example of a Double replacement
AX+ BY - AY +BX
(judge will check if others apply)
_C5H12 + _O2 ---> _CO2 + _H2O

NET IONIC EQUATIONS
Pb(NO3)2(aq) + KOH(aq) --->
Callie has this on her paper and is too lazy to put it on here
how do you balance chemical equations
write correct formulas and change coefficients
