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 intermolecular forces explain why water is a liquid at room temperature?
You think probable to hydrogen bonds.
Does C2H5OH have hydrogen bonds?
C2H5OH is the formula for ethanol, an organic compound. Hydrogen bonds are possible for ethanol at the intermolecular level, between molecules, but not for the intramolecular carbon-hydrogen or the oxygen-hydrogen bonding within the molecule. Hydrogen bonds are much weaker than true chemical bond.A good example of a hydrogen bond is that which makes water a liquid at normal temperature and pressure.
The boiling temperature of water is so much higher than that of methane because water molecules are?
d.polarWater molecules are polar covalent and therefore form attractions between the molecules called hydrogen bonds. Much of the heat that goes into raising the temperature of water to its boiling point goes to breaking the hydrogen bonds first.
How much hydrogen bonds are in hf?
There are no hydrogen bonds in HF.
Are solvent cohesive and temperature stabilization properties of water due to its hydrogen bonds?
hydrogen bonds
Is hydrogen bonding organic?
No, while some organic compounds can form hydrogen bonds, these bonds are not inherently organic. Hydrogen bonds occur where hydrogen is bonded to a highly electronegative element such as oxygen or nitrogen. Organic compounds must contain carbon, which is not related to hydrogen bonding.
Changes in temperature and pH can decrease an enzyme's activity by breaking?
Hydrogen bonds
Many mammals control their body temperature by sweating Which property of water is most directly responsible for the ability of sweat to lower body temperature?
the absorption of heat by the breaking of hydrogen bonds
What will be the first bond or interaction that will be broken while you increase the temperature of a solution?
Hydrogen bonds

What chemical groups are hydrogen acceptors for hydrogen bonds?
A hydrogen acceptors for hydrogen bonds is nitrogen.

What holdes the two strands of a DNA molecule to each other?
Hydrogen bonds
How are bonds between A-T and G-C different?
It is the hydrogen wich bonds between AT and GC the difference is in the number AT have 2 hydrogen bonds GC have 3 hydrogen bonds
