Reactions Flashcards
What are the 5 indications of a chemical reaction
1) solid is produced
2) liquid is produced (often H2O)
3) gas is produced (often CO2)
4) color change
5) energy transfer (endothermic or exothermic)
What is driving force for a chemical reaction? (4)
1) produce a solid
2) produce a liquid
3) produce a gas
4) electron transfer
What is it called to lose an electron?
Oxidation
What is it called to gain an electron?
Reduction
How do carbonate salts decompose?
XCO3 –> XO + CO2
What carbonate salt will spontaneously decompose?
H2CO3
Carbonic Acid
How do chlorate salts decompose?
XClO3 –> XCl + O2
How do hydroxides decompose?
XOH –> XO + H2O
How do peroxides decompose?
XO2 –> XO + O2
Which peroxide will spontaneously decompose?
H2O2
What does XO + CO2 synthesis
XCO3
Carbonate salts
What does XCl + O2 synthesis
XClO3
Chlorate salts
What does XO + H2O synthesis
XOH
Hydroxides
What does XO + O2 synthesis
XO2
Peroxides
What are the 5 types of reactions?
1) Decomposition reaction
2) Synthesis
3) Combustion
4) Single Replacement
5) Double Replacement
What does combustion of a hydrocarbons produce
CxHy + O2 –> H2O + CO2
What does combustion of an element produce
What type of reaction is it like
X + O2 –> XO
Like synthesis
Electrolyte
A solution that will conduct electricity
1) charge particles
2) freely flowing charge
What are strong acids (7)?
HCl HBr HI HClO4 HCl3 HNO3 H3SO4
What is special about hydrogen peroxide
Molecular, doesn’t break apart
When doing net ionic what do you need to remember
Leave solid, liquid, gas, weak acids and molecular molecules alone! Don’t fuck this up
