Stoichiometric Combinations Compounds containing elements
combined in distinct ratios are often formed in daily life reactions
H2O2 and H2O Both compounds occur in nature However, water is relatively stable
How does hydrogen peroxide form?
Think about marriages All of them are not
equally stable Why?
Hydrogen peroxide (H2O2) is formed when lightning strikes.
It will decompose on exposure to light, dust, or metal.
Uses of Hydrogen Peroxide
Home Hair bleach
Industry Bleaching agent for
textiles, paper pulp, leather, oils, fats, etc.
Pollution control: treatment of domestic and industrial effluents
Combustion Revisited
Flames
Incomplete combustion
Incomplete combustion occurs when the supply of air or oxygen is poor.
Water is still produced, but carbon monoxide and carbon are produced along with carbon dioxide.
hydrocarbon + oxygen → carbon monoxide + carbon + water
The carbon is released as soot. Carbon monoxide is a poisonous gas.
Gas fires and boilers must be serviced regularly to ensure they do not produce carbon monoxide.
