Chemical reaction examples used in your home and everyday life
Chemical reactions are all around us. Combustion reactions help release energy to heat our homes and move our vehicles. Oxidation-reduction reactions keep the batteries in our cell phones and laptops functioning. Acid-base reactions take place when cleaning your oven or removing a clog from a drain. Acid-base reactions are also the basis for the Titrations experiment where you will measure the acidity of fruit juices.
The equation of interaction that take place in combustion of propane gas stove used for barbeque:
C3H8 + 5O2 → 4H2O + + 3CO2 + Energy
The energy for the welding torch in is released when hydrogen and oxygen combine to form water.
2H2 + O2 → 2H2O + Energy
Energy from a chemical reaction is used to cook.
Cooking gas or Methane used for burning gas stoves reacts with oxygen to form carbon dioxide, water, and heat.
CH4 + O2 → CO2 + H2O + Heat
Methane Oxygen Carbon Water
dioxide
A number of other household cleaners or toilet Cleaner are formulated with a chlorine-based bleach. These are essentially solutions of chlorine in alkali in which the following equilibrium is set up.
Cl2(g) + OH-(aq) HClO(aq) + Cl-(aq)
The active bleaching agent is HClO(aq), chloric(I) acid.
When a solve article is kept exposed to air/moisture it turns blackish grey. This is because silver reacts with atmospheric oxygen gas to form silver oxide:
2Ag (s) +O2(g)→ 2AgO (s)
Decomposition reaction
If you leave a soda can open for a long time, the carbonic acid (the fizz) decompose into carbon dioxide gas and water.
H2CO3 → H2O + CO2
Rusting of iron articles
4Fe + 3O2 → 2Fe2O3
Rust
