copper sulfate is made up of the elements copper, sulfur, and oxygen. which statements about these substances are true?

copper, sulfur, and oxygen can combine to form copper sulfate, which has properties that are distinct from each of those elements.
copper sulfate is a powdery, yellow solid, while sulfur is a blue - green metal.
copper, sulfur, and copper sulfate are all solids, but they have different properties.
copper, sulfur, oxygen, and copper sulfate all have very different properties.

Explanation:

• A compound (copper sulfate) formed by elements (copper, sulfur, oxygen) has different properties than the individual elements. Copper is a metal (reddish - brown), sulfur is a non - metal (yellow), oxygen is a gas. Copper sulfate is a blue - colored compound.
• Copper sulfate is blue (not yellow), sulfur is yellow (not blue - green metal).
• Copper is a solid metal, sulfur is a solid non - metal, copper sulfate is a solid compound and they have different properties.
• Copper (metal, solid), sulfur (non - metal, solid), oxygen (gas), copper sulfate (compound, solid) all have very different properties.

Answer:

• Copper, sulfur, and oxygen can combine to form copper sulfate, which has properties that are distinct from each of those elements.
• Copper, sulfur, and copper sulfate are all solids, but they have different properties.
• Copper, sulfur, oxygen, and copper sulfate all have very different properties.
