It depends on the crystal. For example diamond is elemental carbon and corundum is aluminum oxide, a compound.
However gems would generally be considered mixtures as they get their colors from impurities.
Iodine is an element, so a pure substance, not a mixture, (so even not homogeneous).
Mixtures and pure substances are both made up of different types of matter. However, mixtures contain two or more substances physically combined, while pure substances contain only one type of substance with a specific composition.
Dehydrated onions are mixtures because they are made up of different compounds, such as water, sugars, proteins, and volatile compounds that give onions their flavor and aroma.
Sugar crystals are typically made for use as a sweetener in food and beverages. They can also be used in baking and candy-making to provide sweetness and texture. Additionally, sugar crystals can be used in drinks like tea and coffee to sweeten them.
Matter is classified as mixtures and substances. Mixtures are made up of two or more different substances that are physically combined, such as saltwater. Substances consist of only one type of atom or molecule, like elements (e.g. gold) and compounds (e.g. water).
Iodine is an element, so a pure substance, not a mixture, (so even not homogeneous).
homogeneous mixtures of a pure solid in the form of its crystals from solution are separated by the technique of crystallization.
A cloud.
Sugar crystal compounds are mixtures, as they are made up of multiple elements bonded together in specific ratios. The sugar crystals are composed of carbon, hydrogen, and oxygen atoms arranged in a specific molecular structure.
what are the similarities of mixtures and compounds?
Swarovski crystals are made of crystal.
one they are both made of a group of atoms
Gemstones are made from mineral crystals, yes.
No, elements are the most basic form of a substance, thus mixtures might be made up from different elents but elements can never be made from mixtures.
Mixtures are materials made up of two different substances which do not combine chemically.
mixtures differ from compounds because mixtures are made up of random things that have no similarities and compounds don't.
In mixtures of salt and water, typically two phases are observed: a solid phase of salt crystals and a liquid phase of water.
