Question

question 3 points 3
which of the following statements describes the separation of the components of a mixture?
water is broken down into hydrogen and oxygen.
salt is isolated from seawater through evaporation.
propane reacts with oxygen to form carbon dioxide and water.
calcium carbonate decomposes to form calcium oxide and carbon dioxide

Explanation:

• Water breaking down into hydrogen and oxygen is a chemical decomposition (not separation of a mixture).
• Salt isolation from seawater via evaporation is a physical separation (seawater is a mixture).
• Propane reacting with oxygen is a chemical reaction (not separation).
• Calcium carbonate decomposition is a chemical reaction (not separation).

Answer:

Salt is isolated from seawater through evaporation.
