law of conservation of mass
the starting mass of a reactant equals the mass of the product
produces or forms
aqueous; a substance dissolved in water
heat ->
the reactants are heated
light ->
the reactants are exposed to light
elec. ->
an electric current is applied to the reactants
synthesis reaction
decomposition reactions
single-displacement reactions
double displacement
Antonie Lavosier
established the law of conservation of math
atoms detail
atoms can be rearragned but they never loose their form
iron and air
when iron is exposed to air it corrodes and forms rust
alumminum and oxygen
when they interact alumminum oxide
copper detail
when it is exposed to air it corrodes and turns blue/green. this coating is called patina.
synthesis reaction example
hydrogen burns into oxygen to form water
decomposition detail
most requires heat, light, or electricity
displacement example
copper is placed in solution of silver nitrate. copper replaces silver nad the silver in turn forms on wire
double displacement example
barium nitrate's reaction wiht postassium sulfate.
dynamite expostion
rapid chemical reaction
energy in reactions
all chemical reactions release or absorb energy.

can be in heat, sound, light, or electricity

the source of the energy is chemical bonds
exergonic reactions example
glo stick
exothermic reaction example
burning wooden
endergoic reaction example
used to coat metal onto a surface like copper on a coin
endothermic reaction example
Epsom salt in water; salt absorbs heat making the water colder
cataylast details
when added to reactions the product forms more rapidly

used to speed the productions of plastics and fibers
tie up reactants to keep from original reaction

brushing or spraying something with lemon juice stops catalysts from reaction
