1. Bronze is a mixture of copper and tin. It is a mixture (not a compound) because the proportions of copper and tin are not exactly the same in all bronze. 2. Glucose is a chemical compound containing three different types of elements. 3. Silver is a pure element, whose chemical symbol is "Ag" 4. Oxygen is the most abundant element in the earth's crust. 5. Face cream is a mixture of two or more liquids, therefore it is an emulsion. 6. Soap lather or foam is formed when foaming agents in soap mixes with water. 7. Aluminium is the most abundant metal in the earth's crust. 8. Tyndall effect is the scattering of light in a colloid when a beam of light is passed through the colloid solution.
