Study Notes
Chemical Changes
- Acid Rain: Precipitation with high levels of sulfuric or nitric acids, resulting from atmospheric pollution, causing ecosystem damage.
- Alkaseltzer: A type of effervescent antacid that undergoes a chemical reaction when dissolved in water, producing carbon dioxide.
- Burning a Match: A combustion reaction where chemical bonds break and new substances such as ash and gases form, releasing heat and light.
- Cooked Eggs: Proteins in eggs undergo denaturation and new bonds form when heated, creating solidified structure.
- Digestion: A complex biochemical process that breaks down food into simpler substances through enzymatic reactions.
- Dying Hair: A chemical process involving the alteration of hair pigments through the application of chemical dyes.
- Firefly Glowing: A bioluminescent chemical process involving the enzyme luciferase that produces light in fireflies.
- Pipes Rusting: A chemical reaction of iron with oxygen and water leading to corrosion, producing iron oxide (rust).
- Zinc and HCl: A chemical reaction that occurs when zinc reacts with hydrochloric acid, producing hydrogen gas and zinc chloride.
Physical Changes
- Boiling Water: A physical transformation where water changes from liquid to vapor without altering its chemical composition.
- Ice Melting: The transition from solid to liquid when ice absorbs heat, maintaining the chemical identity of H2O.
- Mixing Iron and Sand: A physical process where iron filings and sand combine, but no new substances are formed.
- Lava Cooling: Upon cooling, molten rock transforms into solid rock without changing its chemical composition.
- Sublimation of Iodine: A physical change in which iodine transitions directly from solid to gaseous state without becoming liquid.
- Sugar Dissolving: A physical change where sugar molecules disperse in water but retain their chemical identity.
- Weathering of Rocks: A physical process involving the breakdown of rocks due to environmental conditions, affecting their structure but not composition.
