Question

1. put a checkmark next to matter whether its elements, compounds, or mixtures. examples: oxygen (o), gold (au) can be easily separated into individual parts made of only one type of atom examples: water (h₂o), carbon dioxide (co₂) examples: salad, air, saltwater. properties are different from its individual parts is not considered a pure substance two or more separate substances physically mixed two or more atoms chemically bonded

Explanation:

Elements are made of one - type of atom (e.g., Oxygen, Gold). Compounds have two or more atoms chemically bonded (e.g., Water, Carbon dioxide). Mixtures are two or more substances physically mixed, can be easily separated, and are not pure substances (e.g., Salad, Air, Saltwater). Their properties are different from individual parts.

Answer:

Examples: Oxygen (O), Gold (Au): Elements
Can be easily separated into individual parts: Mixtures
Made of only one type of atom: Elements
Examples: Water (H₂O), Carbon dioxide (CO₂): Compounds
Examples: Salad, Air, Saltwater: Mixtures
Properties are different from its individual parts: Compounds, Mixtures
Is NOT considered a pure substance: Mixtures
Two or more separate substances physically mixed: Mixtures
Two or more atoms chemically bonded: Compounds
