Chem 2 Flashcards
Synthesis
Making building
2 or more atoms compounds combine to form a new substance
Balancing equations
Remember only an arrow not an =
just make sure there are equal amounts on each side
atoms can leave compounds
Deomposition
Break down into two or more atoms
Single displacemnt
AKA sustitution reactions
a single element replaces another
A + BC - AC +B
Double displacement
Atoms in different compounds switch places to form two new compounds
AB + CD - AD +CB
Combustion
Burning of a hydrocarbon (compound containing only carbon and hydrogen atoms), in the prescence of oxygen
Hydrogen + oxygen - carbon dioxide + water
Incomplete combustion results in
Any combination of carbon containing compounds
Neutralization
Becomes water and ionic, acid and base cancel out each other. Special kind of double displacement, the hydrogen from the acid reacts with the hydroxide from the base to form H2O
Binary acids
Hydrogen and single non-metal
Oxyacid
Hydrogen and a polyatomic (oxy means oxygen)B
Bases
A molecule with a base of hydroxide or carbonate, or ammonia
Ph scale
How acidic or alkaline (basic)
goes from 0 to 14
Number alkali vs acid
0-6 acid
7 water
8-14 more alkaline
what does ph stand for
Power of hydrogen, concentrartion of Hydrogen
What is a base
pulls protons
