What is difference between hydrogen bonding and hydrogen bridge bonding?

Hydrogen bond is a special type of interaction between molecules: it forms whenever a hydrogen atom, bound to a strongly electronegative (able to attract electrons) atom, at the same time interacts with another strongly electronegative atom having a lone pair of electrons, like oxygen, nitrogen or fluorine. The bond is commonly represented as a dotted line between the hydrogen atom and the other electronegative atom.
When a hydrogen atom is bound to a strongly electronegative atom, a charge separation occurs. The molecule, though it is electrically neutral, has a partial positive charge (indicated as δ+) on one side and a partial negative charge (δ-) on the opposite side. The hydrogen atom is the positive end of the molecule. It interacts with the negative end of a neighboring molecule, forming a "bridge" between the two molecules. Hydrogen bond is a directional bond, meaning that it is stronger when the hydrogen atom is aligned with the two electronegative atoms.
A single hydrogen bond is relatively weak: usually, however, a high number of such bonds forms simultaneously. All together, they play a central role in determining the chemical and physical properties of polar substances like hydrogen fluoride and water.

Weak bonds forming a bridge between water molecules are called?
Adjacent water molecules are connected by the electrical attraction between the oxygen of one water molecule and the hydrogen of another water molecule. This type of bonding is called hydrogen bonding.
How do intermolecular forces affects solvation?
This can be a very complex question that you might be able to use some high end computational chemistry codes. But simply put you have van der waals forces, hydrogen bonding, and ionic bonding. You can think of it like coulumbic repulsion and attraction. hydrogen bonding has a slight negative charge on the oxygen and a slight positive charge on the hydrogen due to the covalent bond and the electron spending more time on the oxygen than the hydrogen, and the oxygens lone pair of electrons (this is inside a water molecule). Outside of the water molecule you dissolve salt nacl = na+, cl- . Since water has a slight negative charge on the oxygen, the oxygens in water molecules surround the Na+ atom pulling it into solution, and the hydrogen slight positive charge surrounds the chlorine anion. generally speaking polar groups like alcohols, ketones, amines,carboxylic acids are water soluble due to hydrogen bonding as long as there is not a large nonpolar R group. Van der waals forces control solubility on oily substances, those with large R groups like oil. since oil is a long chain of carbon it is very covalent with only very small positive and negative charges compared to water. That is why it is impossible to dissolve oil and water. Soap on the other hand has an oily R group bonded to a polar head. so one part of the molecule is polar (hydrogen bonding), and the other is non-polar and oily. A soap molecule can homogenize a solution of water and oil by being the bridge between the water molecule and the oil molecule. Hope this helps.
What is the bridge called between the negative electrons and the positive atoms?
It is called a Salt Bridge
What are elements that form a bridge between the elements on the left and right side of the periodic table?
Transition Metals
Would a galvanic cell work without a salt bridge?
The electrolyte of a commercial galvanic cell normally extends from anode to cathode without interruption by a salt bridge. A salt bridge is normally a teaching tool to help show that: 1. Galvanic half-cells do not produce voltage 2. Conductors and insulators are not necessarily salt bridges. An electrolyte must extend from anode to cathode before the galvanic cell can produce voltage. 3. The chemical composition of the salt bridge can differ from the electrolytes in the half cells. 4. Ions travel through the salt bridge between the cell's anode and cathode. Salt bridges raise more questions than answers. For example: 1. Can the difference between an electrolyte and a conductor be defined? 2. How do ions quickly move through a solid or a long electrolyte? 3. When salt bridge composition differs from the galvanic cell electrolyte(s), must the salt bridge chemically react with the galvanic cell electrolyte(s)? 4. Why does galvanic cell voltage remain nearly constant while anode to cathode distance doubles.

Boxgirder bridge
Does methanol have a higher boiling point than water?
water have inter molecular hydrogen bonding whereas in methanol there is intra molecular hydrogen bonding.the oxygen atom and hydrogen of other molecule have electrostatic force of attraction in water and forms bridge between each other and form an associated structure thus it has more b.p

What is the difference between The London Bridge and The Sydney Harbour Bridge?
There are no similarities between the two bridges. They are completely and totally different.
What is the difference between length and span of a bridge?
The span is the distance between supports. The sum of the span lengths is the bridge length.

What is the difference between the Carey foster bridge and meter bridge?
There is no great difference between between the two in principlebut,In a Carey foster's bridge there is no end resistance whereas in the case of a metre bridge end resistance afffects our readings.Hence Carey foster bridge is more accurate than metre bridge .Carey foster bridge can also measure low resistance and high resistance but a metre bridge cannot do so.
What is the difference between the Suspension bridge and the Beam bridge?
The different between suspension bridge and beam bridge are beam bridge are for short distance but suspension bridge for long distance. Beam bridge are used for highway passes and suspension bridge for wide waterway passes.
