1. Hydrogen peroxide breaks down to form water and oxygen gas.
Cooking or digesting proteins break the peptide bonds and fragment the proteins.
Cakes rise (get fluffy) because the baking soda in the mix breaks down and produces carbon dioxide bubbles.
Propane gas in a grill burns in oxygen to produce heat, carbon dioxide and water.
Cellular respiration is a controlled reaction between glucose and oxygen that produces energy, water and carbon dioxide.
Rockets are fueled by a mixture of hydrogen gas and oxygen gas that combine to release energy and form only water as a product.

An iron fence rusts in air, becoming iron oxide.
Sulfur gas in onions is released when they are cut and combines with the moisture in your eyes to form stinging sulfuric acid.
Caramelization occurs when heat drives hydrogen and oxygen (as water) from sugar.
In a battery zinc metal replaces the copper in copper nitrate.
 Kidney stones are formed when the calcium in compounds in our bodies switches place with the hydrogen in oxalic acid to make two new compounds. One of them is calcium oxalate (kidney stones) So don’t eat a lot of peanuts, chocolate, or sweet potatoes if you have kidney stones because they are high in oxalic acid.
The final step in extracting pure lead from lead ore is to mix lead oxide with carbon. The carbon replaces the lead in the compound and pure lead is left.

3. Na + H2O → NaOH + H2 Li + N2 → Li3N Al2SO3 → O2 + Al
In the last step of the gold refining process, zinc replaces gold in the gold cyanide compound producing pure gold.
Milk of magnesia is actually the compound magnesium hydroxide. The magnesium switches places with the hydrogen in excess hydrochloric acid in your stomach, forming water and magnesium chloride, two neutral compounds.
