Chemical cauldron
Reactions
acid reactions
acid + carbonate --> carbon dioxide + salt + water
vinegar+ bicarb soda
acid + metal --> salt + hydrogen gas
pop test with magnesium
acid + base --> water + salt
indicators
exothermic (released when bonds are broken)
combustion
fuel + oxygen --> carbon dioxide + water
glass on candle practical
cellular respiration
oxygen + glucose --> carbon dioxide + water + energy
corrosion
metal + water + oxygen --> metal oxide
steel wool in acid practical
precipitation
soluble salt + solution --> insoluble salt + soluble salt
solids forms from 2 soluble liquids
barium hydroxide + calcium chloride --> barium chloride + calcium hydroxide
partner swap
synthesis
majority of reactions
formation of a new product
Factors affecting rate of reactions
increase rate
increased surface area
increased heat
decreased volume
increase particles
catalyst
collison theory
enough energy
successful reactions
correct orientation
decomposition
needs energy
breaks bonds apart
heat/electrical energy
electrolysis
water --> Hydrogen + Oxygen
endothermic (absorbed energy when bonds are made)
