synthesis/decomposition
What is synthesis?
A reaction in which two or more substances combine to form a new compound.
A+B-->AB
What is single displacement?
A reaction in which one element replaces another in a compound.
What is a precipitate?
a solid that forms during a reaction
What is Combustion?
chemical combination of a hydrocarbon with oxygen, producing water and carbon dioxide (and usually heat and light)
Balance the equation:
_NH3 + _H2SO4 -> _(NH4)2SO4
2NH3 + 1H2SO4 -> 1(NH4)2SO4
Decomposition is the reaction where...
one substance breaks down into two more substances
ABC-->AB+C
Double displacement is...
A reaction in which the positive ion on one compound replaces the positive ion of another compound.
In a chemical equation, what does (aq) describe?
The molecule remains dissolved in water (or in the solution)
True or False: burning coal is an example of combustion
True
Will Nitrogen form an anion or cation?
Anion.
Nitrogen will have a negative charge when it gains 3 electrons to complete its outer shell.
Name the type of chemical reaction:
Al4+O6-->Al4O6
synthesis
What type of reaction is this an example of?
1Fe + 1CuCl2 -> 1FeCl2 + 1Cu
Single displacement
Will a precipitate form between Potassium ions (K+) and Chloride ions (Cl-)?
No. (Potassium is always soluble).
In order for a reaction to occur, molecules must _________
collide
balance the equation:
__FeS+___O2-->____Fe2O3+____SO2
The numbers are 4, 7, 2, 4
(or 2, 3.5, 1, 2)
Identify the reaction:
KClO2-->KCl+O2
decomposition
2NaOH + 1H2SO4 -> Na2SO4 + 2H2O is an example of...
Double Displacement
Will a precipitate form between Calcium ions (Ca2+) and Carbonate ions (CO32-)?
Yes.
Carbonates almost always form precipitates (except with group 1 ions or ammonium)
What are two factors needed for a collision to cause a reaction?
Correct orientation and sufficient energy.
BALANCE THE EQUATION:
_P4 + _O2 -> _P2O3
1P4 + 3O2 -> 2P2O3
Sodium chloride is a product of what type of reaction?
synthesis--sodium (Na) and chlorine (Cl) combine to produce sodium chloride
Will a single-replacement reaction occur? If so, identify the products. MgCl2 + I2 → ?
Because iodine is below chlorine on the periodic table (or reactivity series), a single-replacement reaction will not occur.
Name the precipitate formed: Barium nitrate + Silver sulfate -->
Barium sulfate
Name 3 of the 5 ways to speed up a reaction
catalyst, concentration, stirring, surface area, temperature
Write the chemical symbols for lithium phosphate
