What is smallest unit of compound?
molecules Why Molecules? Did u tell that? Please improve this answer because I want to know why.
Are all minerals crystalline?
A mineral, by definition is an inorganic solid with a crystalline structure formed naturally. Wood, paper, or any other organic solids are not minerals because they have no crystalline structure and form organically. Plastic is not a mineral either because it is made synthetically out of organic materials. Some organic materials like coal and other hydrocarbons are considered minerals economically. Bones and teeth contain hydoxylapatite that is organically formed but is still considered a mineral, so there are exceptions. Whewellite is organically formed but has a crystalline structure, and is considered a mineral.
How does the structure of a water molecule affect its properties?
Because the water molecule is bent, it is polar
Why molecules are called homo atomic molecules or hetero atomic molecules?
because,acording to their structure they differ.
Why is water versatile molecules?
Water is a versatile molecule because of its polarity.
Is acrylic a mineral?
not it is not because it does not have a crystalline structure
How does a sugar cube dissolve in water?
Sugar cubes (and salt, and many other materials) dissolve in water because water is a powerful solvent. Properties of water molecules cause them to break down the crystalline structure of a sugar cube.Polar MoleculesWater molecules are polar, meaning that one part of the molecule has a slightly positive electric charge, and one part has a slightly negative electric charge. Sucrose molecules also have a part that carries a slight negative charge.Crystalline BondsThe bonds that hold a sugar cube together in a crystalline structure are fairly weak and rely on the sugar molecules being in contact with each other.Water Breaks the Crystalline BondsThe attraction between the negatively charged part of the sugar cube and the positively charged part of the surrounding water molecules pulls the sucrose away from the crystalline structure.Water Surrounds the SucroseThe negatively charged part of the sucrose molecule pulls in water molecules from all directions. They form a shell around the sucrose, preventing it from rejoining the crystalline structure. This layer of water molecules is called the hydration shell.Removing the WaterWhen the water is removed, through evaporation for example, the sucrose molecules come into contact with each other again and reform their crystalline bonds. They are not changed chemically in any way by the process of absorption.
Both carbon dioxide molecules and water molecules have polar bonds?
No. Because of it's symmetry carbon dioxide is nonpolar.FalseLove, Nessa
Is ice a meneral?
Yes because its natural, has a crystalline structure, solid, and is nonliving.
What is the smallest unit of a molecule?
An atom. It not REALLY indivisible, but it is the fundamental building block of molecules.

What size is pumices crystles?
The glasses in pumice actually has no crystalline structure because of their rapid cooling.
Glucose is considered a monomer because?
Because it is a single hexagonal ring structure.
Why molecules are called homo atomic molecules or hetero atomic molecules?
because,acording to their structure they differ.
Are molecules always compounds?
A molecule is formed when two or more atoms join together. And a compound is a molecule that contains at least two different elements. So all compounds are molecules but not all molecules are compounds.
