Why does an ice cubes volume expand?
Ice expands because more hydrogen bonds are formed as water cools. Heat is given off, more hydrogen bonds are formed, and water molecules tend to stick together. The way water molecules link together is open, so more space is formed as ice forms, causing ice to expand.
How a solution is formed?
A solution is formed as individual molecules from the solid are surrounded by molecules of solvent and then diffusing away from the surface of the solid being dissolved.
What is Formed when two atoms bond covalently?

What happens to the water particles when water freezes?
As water begins to freeze and formice , thewater molecules stop moving because they formhydrogen bonds with each other. Hydrogen bonds are weak bonds between hydrogen atoms that are not full bonds, but are able to keep substances together (eg. DNA). This produces a rigid, crystalline structure. However, even if the molecules are held firmly in place, they are not as tightly packed as they are when it is liquid, so that makes ice less dense than water. Because ice is less dense than water, in the winter, only the top 'layer' in ponds and lakes every freeze, so that keeps heat under the surface and allows for life to continue. If ice were more dense than water, then life will not be able to survive throughout winter, because the whole lake/pond would completely freeze; there will be no water underneath ice in that case. But thankfully ice is less dense than water and that will not happen
What is a hypothetical four stage sequence for how life could have first developed on Earth?
firstly small organic molecules formed from simple molecules.secondly these small molecules joined together into proteins and nucleic acids.thirdly molecules that could copy themselves such as RNA provided a way for molecular information to be inherited.fourthly,various organic molecules such as RNA and polypeptides formed "pre cells"
Are hydrogen bonds formed between any molecules that contain hydrogen?
NO! the requirement is for hydrogen to be bonded to a very electronegative atom such as oxygen or fluorine. Alkanes, e.g. C2H6, contain C-H bonds and there are no hydrogen bonds.
Is C6h6 capable of hydrogen bonding?
No, hydrogen bonds are not formed between benzene molecules.
Is a hydrogen bond the strongest that formed between molecules?
Actually it is a weak bond like the attraction between water molecules.
Why is water formed?
Water is formed due to the strong attraction between the hydrogen and oxygen molecules.
When alcohol dissolved in water why temperature of alcohol is increased?
The hydrogen bonds between water molecules and respectively hydrogen bonds between ethanol molecules are broken by mixing; new hydrogen bonds are formed between water and ethanol molecules - this second process is exothermic.
What two molecules are formed by the Hydrogen ions?
one of the hydrogen molecules are water
Weak bond formed between water molecules due to their polarity?
Hydrogen Bond
Hydrogen bonds can form between regions of polar molecules that are?
Hydrogen bonds can be formed between regions of polar molecules that are positive charged. Some of them can be negatively charged.
Where does oxygen in water come from?
Water molecules are formed by the reaction between hydrogen and oxygen.
Hydrogen bonds are formed between molecules when hydrogen is covalently bonded to an element that has a?
Hydrogen bonding can occur when either Nitrogen, Oxygen, or Florine is involved.
What is formed in the neutralization reaction between a strong acid and a strong base?
Water molecules are formed as a result of the reaction between hydrogen and hydroxyl ions.
What is the difference between elements and nutrients?
Nutrients are chemical compounds; they contain molecules - and the molecules are formed from chemical elements.
