Chemical Reactions Review (IP3/IPC3)

•When substances change their properties such as change of state, solubility, shape, or form, these changes are called physical changes. •When a new substance is formed with different compounds and properties, this change is called a chemical change. •And, the reaction that makes this change is called a chemical reaction. Physical changes Chemical changes No …

Review Chemistry IPC4/IPC6 (Grade 11/Grade 12)

Hydrocarbons• Carbon atoms bond to each other by single, double, and triple bonds. • Saturated hydrocarbons contain only single bonds. • Unsaturated hydrocarbons contain at least one double or triple bond. Refining Hydrocarbons• Fractional distillation involves boiling petroleum and collecting each group of components as they condense at different temperatures. • Fractional distillation towers do …
