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 bonds are broken when water is heated to boiling?
The primary bond that is broken when water is boiled is hydrogen bonds. There are other weaker intermolecular forces at work as well, but these are much weaker and not as significant. Once the hydrogen bonds are broken, the water molecules are not held as tightly together and can escape the liquid as gas.
What is broken down and formed in the decomposition of water?
Hydrogen and Oxygen are the two elements that are formed when water decomposes.
How do molecules use hydrogen bonds?
Hydrogen bonds are weak electro-static forces of attraction between a highly electro-negative atom like F, O or N and Hydrogen of the same or different molecules. when a hydrogen bond is formed within a molecule, it is called Intra-molecular Hydrogen bond and when it is formed between two separate molecules, it is called inter-molecular hydrogen bond. hydrogen bond has a major role in determining various properties of a compound like the boiling point. for example, water, which is expected to be a gas at room temperature, is a liquid due to the hydrogen bonds formed between the oxygen of one water molecule and the hydrogens of the other water molecules. a water molecule can form up to 4 hydrogen bonds and so, it requires more energy to change the state of water from liquid to gas, as all the hydrogen bonds are to be broken to change its state. :)
Why can a hydrogen bond dissolve in water?
A hydrogen bond does not dissolve, but it can be broken. Water molecules form hydrogen bonds with each other. This is why water has so many unique properties, such as its high heat capacity.
How is a chemical bond usually broken?
Chemical bonds are both formed and broken during chemical reactions. For example, bonds are formed and broken in the synthesis reaction 2H2 + O2 = 2H2O. The bonds in both diatomic oxygen and hydrogen are broken, forming new bonds to form a water molecule.

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 Hydrogen bonds are easily?
Hydrogen bonds are easily broken. Think of swimming through water.

Once the hydrogen bonds are broken, the water molecules are not held as tightly together and can escape the liquid as gas.
Why does water have a high and specific heat?
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
Are hydrogen bonds easily broken?
Heat. Intermolecular Hydrogen bonds (between two water molecules) are broken as water is heated to boil.The intramolecular hydrogen bonds (between H and O) stay intact
What is broken down and formed in the decomposition of water?
Hydrogen and Oxygen are the two elements that are formed when water decomposes.
How are sugars formed and broken down?
sugar is formed by disaccharides and broken down by water or 20 hydrogen
What is water when heated?
Water molecules are attracted to each other, resulting in the formation if weak chemical bonds, called hydrogen donds. When water is heated the heat energy disrupts the hydrogen bonds reulting in hydrogen bonds between water molecules to be broken.
What is heating water?
Water molecules are attracted to each other, resulting in the formation if weak chemical bonds, called hydrogen donds. When water is heated the heat energy disrupts the hydrogen bonds reulting in hydrogen bonds between water molecules to be broken.
What bonds are broke and or formed in the splitting of water(electrolysis)?
The bonds O-H are broken.
What happened when water is heating?
Water molecules are attracted to each other, resulting in the formation if weak chemical bonds, called hydrogen donds. When water is heated the heat energy disrupts the hydrogen bonds reulting in hydrogen bonds between water molecules to be broken.
