Answer 1

"Solid solid mixtures are generally heterogeneous." - A 'solidified mixture of molten metals​' is an exception to this statement.

• Electrol powder - Electrol powder is a heterogeneous mixture. Electrol powder contains 'anhydrous dextrose' (glucose).
• The ground mixture of nuts - Mixed nuts at a party is a kind of heterogeneous mixture that can be separated. Simply arrange the pile in separate piles for each type of nut and you will break down a very different mixture of its ingredients.
• Cement concrete - Concrete is a type of artificial stone. Concrete is prepared by a specific process of binding some material (cement), fine-grained material (sand), coarse-grained material (cobalt or stone particles), and a chemical process mixed with water. The mixture is poured into the required shape before freezing. It is also a heterogeneous mixture.
• The solidified mixture of molten metals​ - A solidified mixture of molten metals is a homogeneous mixture. The mixture is said to be homogeneous as it has a uniform mixture and no visible boundary of separation between the components. Moreover, the components cannot be seen even by a microscope.
