Combustion & Rusting with suitable word equations only?

उत्तर
Combustion:
- It is confined to a variety of materials.
- Oxygen is required.
- Moisture is not essential.
- Oxide of carbon and hydrogen formed.
- Heat is evolved at a rapid rate and cause sudden rise in temperature.
Rusting:
- It is confined only to iron.
- Oxygen is required
- Moisture is essential.
- Oxide of iron formed.
- Heat is evolved at a slow rate and cause slight rise in temperature.
The equation formed in Combustion is
Hydrocarbon + Oxygen → Carbon Dioxide + Water Vapour.
CxHy + O2 → CO2 + H2O
The equation formed in Rusting is Iron + Oxygen →Iron [III] oxide Rust Hydrated iron(III) oxide
\[\ce{4Fe + 3O2-> 2Fe2O3 ->[x H2O][moisture] Fe2O3.xH2O}\]
