which is a mixture?\n○ sodium metal\n○ chlorine gas\n○ sodium metal and chlorine gas\n○ sodium chloride (salt) and water

Answer

Brief Explanations:

A mixture is a combination of two or more substances where each substance retains its own chemical identity. Sodium metal is an element, chlorine gas is an element, and sodium chloride (salt) is a compound. A combination of sodium chloride and water is a mixture as they are physically combined and can be separated by physical means like evaporation. A combination of sodium metal and chlorine gas would react chemically to form sodium chloride and is not just a simple mixture in the non - reacted state.

Answer:

sodium chloride (salt) and water
