most common everyday chemical reactions and also one of the most important, since this is how plants produce food for themselves and animals and convert carbon dioxide into oxygen.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Here is the overall equation for aerobic cellular respiration:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (36 ATPs)
The overall chemical equation for one form of anaerobic respiration is:
C6H12O6 → 2C2H5OH + 2CO2 + energy
For example, the combustion reaction of propane, found in gas grills and some fireplaces, is:
C3H8 + 5O2 → 4H2O + 3CO2 + energy
Here is the chemical equation for the rusting of iron:
Fe + O2 + H2O → Fe2O3. XH2O
These reactions seem simple in practice but often consist of multiple steps. Here is the overall chemical equation for the reaction between baking soda and vinegar:
HC2H3O2(aq) + NaHCO3(aq) → NaC2H3O2(aq) + H2O() + CO2(g)
Sodium chloride is not the only salt that may be formed. For example, here is the chemical equation for an acid-base reaction that produces potassium chloride, a common table salt substitute:
HCl + KOH → KCl + H2O
