Ibrahim mixes salt and sand together. He can still see individual grains of salt and sand, and he can separate them using a magnet and water. What type of substance is this mixture?

15

Which of the following is an allotrope of carbon?

Victor is looking at a glass of milk. He notices that it appears uniform but when he looks closely, he can see tiny particles that scatter light. Milk is an example of which type of mixture?

17

Emma is studying the density of an unknown liquid. She measures its mass and volume and finds that its density is 0.8 g/cm³. She compares it to water (1.0 g/cm³). Will this liquid float on water?
