which jar contains a mixture?\n a jar of solid carbon\n a jar of carbon dioxide gas\n a jar of liquid copper\n a jar of copper and water

Answer

Answer:

a jar of copper and water

Explanation:

Step1: Recall the definition of a mixture

A mixture is a combination of two or more substances that are not chemically combined.

Step2: Analyze each option

  • A jar of solid carbon: Carbon is an element, so it is a pure substance, not a mixture.
  • A jar of carbon dioxide gas: Carbon dioxide ($CO_2$) is a compound (a pure substance formed by chemical combination of carbon and oxygen), not a mixture.
  • A jar of liquid copper: Copper is an element, so it is a pure substance, not a mixture.
  • A jar of copper and water: Copper (a solid metal) and water (a liquid compound) are two different substances that are not chemically combined. So this is a mixture.
