decomposition of a metal carbonate (CO3-2) turns into
a metal oxide + carbon dioxide (CO2)
decomposition of a metal nitrate (NO3-1) turns into
a metal nitrite (NO2) + oxygen gas (O2)
decomposition of a metal hydroxide (OH-1) turns into
metal oxide + water (H2O)
synthesis of a metal oxide + water (H2O)
forms a BASE
has OH in formula
has aq at end
synthesis of non metal oxide + water (H2O)
forms an ACID
starts with H
has aq at the end
combustion
the reaction of a substance with oxygen to produce oxides, heat, light
how to recognize :
- O2 will be one of the reactants.
- heat, light, and an oxide will be the products
complete combustion
fuel + oxygen ——> carbon dioxide + water
incomplete combustion
fuel + oxygen ——> carbon dioxide + water + carbon monoxide + carbon.
