3. Sodium reacts with acids to produce hydrogen gas.

4. Sodium's melting point (the point where it turns from solid to liquid) is 97.8°C.

5.Sodium is soft enough to be cut with a knife.:

6. Sodium reacts violently with water.:

Choices: Physical Change or Chemical Change

choose the correct answer

1 answer

Here are the classifications for each statement based on whether they describe a physical or chemical property:

Column A

  1. Sodium is a silvery-white metal. - Physical Property

  2. When heated, sodium burns, producing a bright yellow flame. - Chemical Property

  3. Sodium reacts with acids to produce hydrogen gas. - Chemical Property

  4. Sodium's melting point (the point where it turns from solid to liquid) is 97.8°C. - Physical Property

  5. Sodium is soft enough to be cut with a knife. - Physical Property

  6. Sodium reacts violently with water. - Chemical Property

So, the correct answers are:

  1. Physical Property
  2. Chemical Property
  3. Chemical Property
  4. Physical Property
  5. Physical Property
  6. Chemical Property
