Which of the following contributes the most toward the ability of water to form hydrogen bonds?
Water can form hydrogen bonds because of the polarity of its oxygen hydrogen bonds. In these bonds, oxygen has a partial negative charge and hydrogen has a partial positive charge. Because of this, the partially positive hydrogens on one molecule can form bonds with partially negative oxygen atoms in other water molecules. These intermolecular bonds are hydrogen bonds.
What does partially positive mean?
half positive ,and if u dont know what that means then go back to 2 grade ,,, Partially positive means that the positive charge is half the strength of a regular positive charge. That is why in hydrogen bonding where the hydrogen ions have a partial positive charge, hydrogen bonds are the weakest bonds.
How does whater form hydrogen bonds?
Water, H2O, is a polar molecule in which the larger, more electronegative oxygen atom develops a partial negative charge, and the smaller, less electronegative hydrogen atoms develop a partial positive charge. The slightly negative oxygen atom of one water molecule is attracted to the slightly positive hydrogen atom of another water molecule. This weak attraction is called a hydrogen bond.

The dashed lines represent the hydrogen bonds and the δ- represents a partial negative charge, and δ+ represents a partial positive charge.
What are the forces between water molecules that hold them together in the solid and liquid state called?
Hydrogen bonding. Hydrogen bonding is a dipole-dipole interaction in which a hydrogen atom bonded to a highly electronegative atom (either O, N, or F) develops a partial positive charge. This partial positive charge allows the formation of a weak bond with another electronegative atom (again, either O, N, or F).
Why does hydrochloric acid though a covalent compound ionize?
HCl is strictly speaking - a polar covalent molecule with a partial positive charge on hydrogen and a partial negative charge on chlorine. When this is dissolved in water, water too being a polar molecule with a partial positive charge on hydrogen and a partial negative charge on oxygen, hydrogens of HCl are surrounded by oxygens of water forming dipole dipole bonds. So also the chlorines are surrounded by hydrogens of water. When the dipole-dipole bonds are formed, the original bond between H and Cl weakens and ultimately breaks leading to ionization.
A hydrogen bond forms when a positively charged hydrogen ion bonds to a negatively charged atom?
No, hydrogen bonding occurs in covalent compounds in which hydrogen is bonded to nitrogen, oxygen, or fluorine. These elements will pull electrons towards them getting a partial negative charge and giving hydrogen a partial positive charge.The actual hydrogen bonding occurs when the partial positive charge on one such molecule is attracted to the partial negative charge on another.Technically it isn't a type of bond.

Why doesn't hydrogen in hydrocarbons make hydrogen bonds?
For hydrogen atoms to have the ability to create hydrogen bonds they must be bonded to an electronegative atom such as fluorine or oxygen. (This creates a partial positive charge on the hydrogen.) Since hydrocarbons are composed of only hydrogen and carbon there is no polarity in the bonds (electronegativity difference of 0.4).

Which water molecule has a partial positive charge?
hydrogen is partially positive and oxygen is partially negative so your answer is oxygen
What is the definition of partial charge?
Partial charge are charge that are smaller than the charge of the electron.And, they are produced by distribution of electrons in chemical bonds.

Do hydrogen bonds form from an equal charge distribution within a molecule?
No. Hydrogen bonds form as a result of highly unequal charge distribution.
Why water makes covalent bonds?
Water does not make covalent bonds with other molecules or atoms. The chemical bonds between the oxygen and the two hydrogen atoms in a water molecule are covalent bonds, in which electrons are shared. Oxygen is a larger and more electronegative atom than hydrogen, so the electrons are not shared equally. The oxygen atom attracts the electrons more strongly, so it develops a partial negative charge, and the hydrogen atoms develop a partial positive charge. The oxygen and hydrogen bonds are said to be polar covalent and because the hydrogen atoms and oxygen atom are at opposite ends of the molecule, the water molecule is polar. Because of this, the oxygen atom of one water molecule is attracted to the hydrogen end of another water molecule. This is called a hydrogen bond, which is a weak electrostatic attraction, but not a chemical bond in that electrons are not being shared or transferred between the water molecules. Hydrogen bonding gives water its unique properties, and is very important in biological molecules like DNA and proteins. Please refer to the related link below. The symbol that looks like a lower case "d" is a delta symbol and means partial. So "d+" means partial positive charge and "d-" means partial negative charge.
What is positively and negatively charged in a water molecule?
it says oxygen acts negativw so most likely hydrogen on the bottom acts positive
