How would our daily lives be changed if water were not a compound but a mixture of hydrogen and oxygen?
If water were a mixture of hydrogen and oxygen instead of a compound, the consequences would be dramatic.
Hydrogen and oxygen would retain their individual properties in the mixture. Hydrogen is highly flammable and burns explosively, while oxygen vigorously supports combustion.
This means water would be highly dangerous - instead of extinguishing fires, it would potentially cause explosions. Drinking water would be hazardous as hydrogen could ignite inside the body.
Life as we know it would be impossible because aquatic organisms could not survive, and the water cycle would not function.
The components could be easily separated by physical means, making water unstable. Weather patterns, agriculture, and all water-dependent processes would be fundamentally altered.
Explanation
The chapter emphasizes that 'The properties of compounds are different from those of elements forming that compound.' Water's life-sustaining properties (extinguishing fires, supporting life, remaining stable) exist precisely because hydrogen and oxygen are chemically bonded in a fixed 2:1 ratio. In a mixture, as the chapter states, 'each substance retains its properties' and 'components do not react chemically with each other.'
