Identify any ten chemical reactions taking place around you and try to write the
corresponding balanced chemical equations yourself.
Answers
Answer:
The ten chemical reactions taking place around us are:
(1) The rusting of iron:
Fe + O2 + H2O → Fe2O3.xH2O
(2) Photosynthesis:
6 CO2(g) + 6 H2O(l) + Energy → C6H12O6(s) + 6 O2(g)
(3) Acid-Base Neutralization (like in case of acidity in the stomach)
NaHCO3(s) + HCl (aq) → NaCl (s) + CO2 (g) + H2O (l)
(4) Burning of carbon:
C + O2 → CO2
(5) Aerobic Respiration:
C6H12O6 (s) + 6 O2 (g) → 6 CO2 (g) + 6 H2O (l) + energy
(6) Anaerobic Respiration:
C6H12O6 (s) → 2 C2H5OH(aq) + 2 CO2 (g) + Energy
(7) Combustion of octane in engines:
2 C8H10 (l) + 21 O2 (g) → 16 CO2 (g) + 10 H2O (g)
(8) The formation of the ozone layer:
3 O2 (g) → 2 O3 (g)
(9) Tarnishing of Silver:
Ag (s) + S (s) → AgS (s)
(10) Copper vessels turn green on exposing to moist air:
2Cu(s) + H2O (l) + CO2(g) + O2(g) → Cu(OH)2(s) + CuCO3(s)
