Chemical Reactions and Equations Quiz

Chemical Reactions and Equations

• Define a chemical reaction: A chemical reaction is a process where one or more substances (reactants) change into one or more different substances (products).
• Example of a chemical reaction: Iron + Water → Iron Oxide + Hydrogen

• Saturated and unsaturated hydrocarbons: Saturated (single bonds) unsaturated (double or triple bonds).
• Ethanol: Properties and uses of ethanol (needed)

Periodic Classification of Elements

• Mendeleev's periodic law: Elements are arranged in order of increasing atomic weight, and elements with similar properties appear at regular intervals
• Modern periodic law: Elements are arranged in order of increasing atomic number and elements with similar properties appear at regular intervals
• Atomic radius: Distance from the center of the nucleus to the outermost electron
