Types of Chemical Reactions and Predicting Products Quiz Flashcards
Types of Chemical Reactions
Synthesis
Decomposition
Single replacement
Doube replacement
Combustion
Synthesis
Two substances react to form a compound
Also known as composition or combination
Spontaneous
Metal and nonmetal
Opposite of decomposition
Metal Oxides
Metal with oxygen
Metal Hydroxides
Metal with hydroxide
Nonmetal Oxides
Nonmetal with oxygen
Oxyacids
Hydrogen, oxygem, and nonmetal
Salts
Anion of acid and cation of base
Decomposition
A compound produces two simpler substances
Often requires energy
Opposite of synthesis
Metal Carbonates
Metal with carbonate
Metal Chlorates
Metal with chlorate
Metal Chloride
Metal with chloride
Single Replacement
One element replaces a similar element in a compound
Also known as single displacement
Only time to write no reaction
Metal Will Replace
Metal OR hydrogen
Activity Series
Most active metals are above
Element above element being replaced yes
Halogens Activity Series
Most active above
H2CO3 Room Temperature
H2O + CO2
Phosphorus
Tetratomic
Diatomics State
All gas except bromine is liquid and iodine is solid
Zinc Charge
2+
Double Replacement
Ions of two compounds in aqueous solutions switch to form two new compounds
Results of Double Replacements Mostly
Precipitate or gas
Acid neutralization forms water and salt and can be told by heat
NR is two aqueous
Combustion
Hydrocarbon react with oxygen releasing large amount of energy
Combustion is fire so products are gas
Combustion Predicting Products
Hydrocarbon + O2 –> CO2 + H20
Order to Balance Combustion
Carbon, hydrogen, then oxygen
If uneven, make hydrocarbon coefficient 2
CIE
Breaks down aquaous to atomic level
Include charge
Include states of matter
Include coefficients and diatomic if applicable
NIE
Cancels out, precipitate or gas is all thats left
Charge
States of matter
Coefficients and diatomic if applicable
Spectator Ions
What are canceled in NIE
Small Covalent
Gas
Bases
OH
Dissolve
Ions seperate to atomic level
