Dec 19, 2016 · A mixture is when two or more substances combine physically together.. However, in water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone.
Two liquids that do not really mix well together, such as oil and water, are described as immiscible. Two liquids that appear to mix completely together are said to be miscible. Water and ethanol are one example of a pair of miscible liquids, because you can take any amount of ethanol and mix it with any amount of water and you will always end up with a clear, colorless liquid just like the ...

An element is a substance composed of a single type of atom. Hydrogen (element symbol H) and oxygen (element symbol O) are examples of elements. You may have heard water called “H2O.” The name refers to the chemical formula of water, H2O. So, water is made from elements, but is not itself an element. Before people knew about atoms and molecules, wa...
When two atoms form a chemical bond, they make a molecule. Hydrogen and oxygen are both elements, but they also normally exist as molecules consisting of two atoms (H2 and O2). Because hydrogen forms bonds with oxygen to make water, water is a molecule. Water is also a compound. Sometimes people use the term “molecule” and “compound” interchangeabl...
Another common question is whether water is a mixture. The thinking is that since water consists of a combination of hydrogen and oxygen atoms, it must be a mixture. However, scientists define a mixture to be a material produced when two substances are physically combined. If you release gas from hydrogen cylinder and oxygen cylinders into a space,...

It is usually separated from tea leaves by filtration. B) Because the composition of the solution is uniform throughout, it is a homogeneous mixture. A) Orange juice contains particles of solid (pulp) as well as liquid; it is not chemically pure.
Sep 13, 2019 · Immiscibility is the property where two substances are not capable of combining to form a homogeneous mixture. The components are said to be "immiscible." The components are said to be "immiscible." In contrast, fluids that do mix together are called "miscible."

What is the difference between a miscible liquid and an immiscible mixture?
Oil and water are two liquids that are immiscible – they will not mix together. Liquids tend to be immiscible when the force of attraction between the molecules of the same liquid is greater than the force of attraction between the two different liquids.
