Calcium chloride is an ionic compound, in which calcium and chlorine are chemically combined, forming a pure substance, and as such is homogeneous, but not like a homogeneous mixture. A homogeneous mixture is made of components that are notchemically combined.
Calcium itself is an element and is a pure substance, so it is a homogeneous material. It is not a mixture at all.
Chalk is a heterogeneous substance because it is composed of various materials such as calcium carbonate, quartz, clay, and other minerals. These materials are not uniformly distributed throughout the chalk, resulting in a non-uniform composition.
Calcium bromide, CaBr2, is a compound. It is not an element, because elements are individual species and they are found in the periodic table. It is not a homogeneous or heterogeneous mixture, because it is a single entity.
Green ink is homogeneous because it is a single phase solution where the ink molecules are evenly distributed throughout the solution.
Plaster is neither a homogeneous nor heterogeneous mixture. Plaster (gypsum) is a compound, Plaster of Paris / Calcium Sulfate or also called Gypsum is composed of calcium sulphate (CaSO4) and water (H2O). Its chemical name is calcium sulphate dihydrate (CaSO4. 2H2O).
Calcium itself is an element and is a pure substance, so it is a homogeneous material. It is not a mixture at all.
It's an element. Check your periodic table.
Rice grits is homogeneous, corn grits is homogeneous, rice and corn grits mixed is heterogeneous.
Chalk is a heterogeneous substance because it is composed of various materials such as calcium carbonate, quartz, clay, and other minerals. These materials are not uniformly distributed throughout the chalk, resulting in a non-uniform composition.
