Carbon Dioxide + Water = Carbonic Acid
- This reaction occurs when carbon dioxide gas dissolves in water, forming a weak acid.
Iron + Oxygen + Water = Hydrated Iron(III) Oxide (Rust)
- This is the reaction for the rusting of iron, where iron reacts with oxygen in the presence of water.
Hydrogen + Oxygen = Water
- This is a basic synthesis reaction where hydrogen gas reacts with oxygen gas to form water.
Sodium + Water = Sodium Hydroxide + Hydrogen
- When sodium metal reacts with water, sodium hydroxide and hydrogen gas are produced.
Magnesium + Hydrochloric Acid = Magnesium Chloride + Hydrogen
- This reaction involves magnesium metal reacting with hydrochloric acid to produce magnesium chloride and hydrogen gas.
Calcium Carbonate + Hydrochloric Acid = Calcium Chloride + Carbon Dioxide + Water
- This is an example of an acid-carbonate reaction, commonly demonstrated with limestone or marble chips reacting with hydrochloric acid.
Zinc + Sulfuric Acid = Zinc Sulfate + Hydrogen
- In this reaction, zinc metal reacts with sulfuric acid to produce zinc sulfate and hydrogen gas.
Copper(II) Oxide + Hydrogen = Copper + Water
- This is a reduction reaction where copper(II) oxide reacts with hydrogen gas, producing copper metal and water.
Ammonium Chloride = Ammonia + Hydrochloric Acid
- This decomposition reaction is often demonstrated using heat, where ammonium chloride breaks down into ammonia and hydrochloric acid gases.
Carbon Dioxide + Water + Light Energy = Glucose + Oxygen
This process occurs in the chloroplasts of plants, where they use sunlight (light energy) to convert carbon dioxide from the air and water from the soil into glucose, a sugar molecule, and oxygen gas. This reaction is fundamental to the survival of life on Earth, as it is the primary source of organic compounds and oxygen in the Earth’s atmosphere.
Methane + Oxygen = Carbon Dioxide + Water
This is a common example of complete combustion where a hydrocarbon reacts with oxygen to produce carbon dioxide and water, typically releasing heat and light.
