Pure silver is homogeneous.It has no allotropic phase.
Silver ore is a heterogeneous mixture, as it contains various minerals and impurities along with the silver.
Silver nitrate is soluble in water. All solutions are homogeneous mixtures.
The mixture of silver nitrate in water is a homogeneous mixture. A homogeneous mixture is one where the components are uniformly distributed and indistinguishable to the naked eye. In this case, silver nitrate dissolves completely in water, creating a solution where the silver ions and nitrate ions are evenly dispersed throughout the water molecules.
Silver oxide is a compound, which is a chemical substance composed of two or more elements in fixed proportions. It is not a mixture, as it does not have varying composition like mixtures do, and it does not contain only one type of atom like elements do.
The copper wire in silver nitrate forms a heterogeneous mixture. In this case, the copper wire does not dissolve in the silver nitrate, so they physically remain as separate substances within the mixture.
Silver is not a homogeneous mixture or a heterogeneous mixture, it is a pure element. Silver does appear in homogeneous mixtures and heterogeneous mixtures such as sterling silver and silver nitrate.
No, sterling silver is not a heterogeneous mixture. It is a homogeneous mixture made up of 92.5% silver and 7.5% other metals such as copper.
Sterling silver is an alloy of silver containing 92.5% by weight of silver and 7.5% by weight of other metals, usually copper. The sterling silver standard has a minimum millesimal fineness of 925. That makes it a heterogeneous mixture.
Silver ore is a heterogeneous mixture, as it contains various minerals and impurities along with the silver.
A silver plate would be a heterogeneous mixture if there is a metal alloy in it also. If it was pure silver, then it would be a homogeneous mixture. Assuming that there is a metal alloy comprised with the silver plate, it is most likely a heterogeneous mixture.
Quartz is a homogeneous substance. It is the compound silicon dioxide, SiO2.
18 karat gold is a homogeneous mixture. It consists of 75% gold and 25% other metals, such as copper and silver, which are uniformly distributed throughout the gold.
Silver nitrate is soluble in water. All solutions are homogeneous mixtures.
Silver ingots, as we normally see them, are usually essentially Pure Silver (element) with a very small percent of impurities alloyed (mixture.)
Sterling silver is not a mixture; it is a homogeneous solid solution made up of 92.5% silver and 7.5% other metals, typically copper. It is considered a pure substance due to its consistent composition throughout.
The mixture of silver nitrate in water is a homogeneous mixture. A homogeneous mixture is one where the components are uniformly distributed and indistinguishable to the naked eye. In this case, silver nitrate dissolves completely in water, creating a solution where the silver ions and nitrate ions are evenly dispersed throughout the water molecules.
Sterling silver is a homogeneous mixture composed of 92.5% silver and 7.5% of other metals like copper. It is not a compound because it does not involve a chemical reaction combining different elements.
