When 2 amino acids link together what bond is formed?
carboxyl group of one molecule of amino acid and amino group of the other molecule of amino acid by releasing a molecule of water.
When heating a sample of pure water to the boiling point why doesn't all of the water instantly vaporize when you reach the boiling point?
as each molecule of water evaporates it takes heat with it, lowering the temperature of the surrounding water, so it takes time before every molecule evaporates.
What is one type of molecule that forms hydrogen bonds with each other?
The most well known molecule that hydrogen bonds is water. This is why water has such a high boiling point and high surface tension.
Which end of a phospholidid is attracted to water?
The hydrophilic head which is made up of a phosphate group and a polar molecule.
What are the parts of a phosphlipid molecule?
There are two parts to the phospholipid molecule. One is a hydrophobic hydrocarbon chain, which points away from water. The other is a hydrophilic phosphate ionic group, often represented as the "head" of the molecule, which points towards water.
When is a symmetrical molecule polar?
same
Both carbon dioxide molecules and water molecules have polar bonds?
No. Because of it's symmetry carbon dioxide is nonpolar.FalseLove, Nessa

Is CH3OH polar or non polar?
CH3OH is a polar molecule owing to the polarity rendered by the -OH group. Its structure can be thought of as very similar, if not exactly, to the water molecule, and the CH3- group decreases the polarity as compared to water.
Why is melting point for water higher than alcohol?
Water has hydrogen bonding between molecules. The hydrogen in one molecule is attracted to the oxygen in another molecule of water by electrostatic interaction. Water has a melting point of 0 ºC.In carbon dioxide there is no attraction between the molecules. Each molecule is non-polar so only van der Waal forces (also known as London forces or dispersion forces) are weak because the molecule is small.Water has higher intermolecular forces.

Is pentanol water soluble?
The OH group makes it slightly water soluble while the carbon group resists solubility. The 3-pentanol molecule is slightly water soluble.
Nonpolar molecule that is not soluble in water?
Lipid are nonpolar molecules that is not soluble in water.
What are the parts of the phosopholipid molecule?
There are two parts to the phospholipid molecule. One is a hydrophobic hydrocarbon chain, which points away from water. The other is a hydrophilic phosphate ionic group, often represented as the "head" of the molecule, which points towards water.
Why does water molecule have a high boiling point and melting point?
hydrogen bonding increases the intermolecular attractions and therefore increases the boiling point and melting point.
Is o-toluidine soluble in NaOH?
no it is not. the molecule does not react with the (polar) water molecule, and when NaOH is added the Na and OH dont react with NH2 either (a major functional group on the toluidine molecule) it is not soluble in water either, but when acid is added the NH2 group becomes NH3 and (due to its ionic nature) dissolves.
What is produced by the addition of a phosphate group to a molecule of ADP?
Adenosine diphosphate (ADP) plus a phosphate group forms adenosine triphosphate (ATP).
