Question

classify each of the properties as a physical property or a chemical property. drag each item to the appropriate bin. view available hint(s) the melting point of sugar the smell of vinegar the color of aluminum wire the reactivity of iron with oxygen the explosiveness of fireworks the flammability of ethanol the luster of silver jewelry physical property chemical property

Explanation:

• Physical property: These are characteristics that can be observed or measured without changing the substance's chemical composition.
• The melting point of sugar: It describes a physical state change (solid to liquid) without altering the sugar's chemical structure.
• The smell of vinegar: Odor is a physical property as it doesn't involve a chemical reaction.
• The color of aluminum wire: Color is a visual physical trait.
• The luster of silver jewelry: Luster (shininess) is a physical appearance property.
• Chemical property: These are characteristics that describe a substance's ability to undergo a chemical change.
• The reactivity of iron with oxygen: This involves a chemical reaction (rusting) to form a new substance (iron oxide).
• The explosiveness of fireworks: Explosions are chemical reactions that produce new substances.
• The flammability of ethanol: Burning (a chemical reaction) is involved.

Answer:

• Physical property: the melting point of sugar, the smell of vinegar, the color of aluminum wire, the luster of silver jewelry.
• Chemical property: the reactivity of iron with oxygen, the explosiveness of fireworks, the flammability of ethanol.
