What else can I help you with?
Why when you freez water the ice is bigger?
When water freezes, the molecules slow down and come closer together, forming a crystalline structure. This causes the ice to take up more space than the liquid water did, leading to an increase in volume and expansion.
What is smallest unit of compound?
molecules Why Molecules? Did u tell that? Please improve this answer because I want to know why.
Why must a mineral be solied to be called minerals?
Minerals must be solid because they are naturally occurring inorganic substances with a defined chemical composition and crystal structure. Liquids and gases are not considered minerals because they do not possess a crystalline structure.
How does the structure of a water molecule affect its properties?
Because the water molecule is bent, it is polar
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.
Is ice a molecule?
Ice is not a molecule, but rather a solid composed of water molecules that are arranged in a specific crystalline structure. Each water molecule in ice is made up of two hydrogen atoms and one oxygen atom bonded together.
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.
What is the significance of the concept of "resonance structures" in understanding the electronic structure of molecules?
Resonance structures are important in understanding the electronic structure of molecules because they show different ways that electrons can be distributed within a molecule. This helps us understand the stability and reactivity of the molecule, as well as predict its properties and behavior.
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.
Why are resonance structures used to model certain molecules?
Resonance structures are used to model certain molecules because they provide a more accurate representation of the electron distribution in the molecule. The actual structure of the molecule is often a hybrid of the different resonance structures, which helps to explain the stability and reactivity of the molecule. Resonance structures are particularly useful for molecules with delocalized electron systems, such as aromatics or carbon-carbon double bonds.
A phospholipid molecule has a polar and a nonpolar end because of this water molecules form what kind of bond?
hydrogen bonds with the polar end of the phospholipid molecule
What happens when water molecule and oxygen molecule are put in the same container?
The water molecule and oxygen molecule will stay as separate entities in the container. Water molecules will remain as H2O and oxygen molecules will remain as O2 because each molecule has its own unique structure and properties. They will not chemically react with each other unless external conditions (like high temperature or a catalyst) are present to facilitate a reaction.
What is the smallest unit of a molecule?
An atom. It not REALLY indivisible, but it is the fundamental building block of molecules.
