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

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.
