Which chemical equation is balanced.

pantera1 [17]

Okay
Mr (H2O)= 18g
therefore moles of H2O
is 720.8/18= 40.04mol
the ratio of H2 to O2 to H2O is
2 : 1 : 2
so moles of H2 is same as H2O here
H2= 40.04moles

moles of O2 is half
so 40.04 x 0.5
20.02moles

grams of O2 is
its moles into Mr of O2
that's 20.02 x 32 = 640.64g

Cohesion, adhesion, and surface tension are characteristics of water that ________. increase when pH increases increase when tem

Ray Of Light [21]

Answer:

are a result of hydrogen bonding.

Explanation:

The surface tension is the amount of energy required to stretch or increase the surface of a liquid by a unit area. Liquids that have strong intermolecular forces also have high surface tensions. Thus, because of hydrogen bonding, water has a considerably greater surface tension than most other liquids.

Another example of surface tension is capillary action. A thin film of water adheres to the wall of the glass tube. The surface tension of water causes this film to contract, and as it does, it pulls the water up the tube. Two types of forces bring about capillary action.

One is cohesion, which is the intermolecular attraction between like molecules (in this case, the water molecules). The second force, called adhesion, is an attraction between unlike molecules, such as those in water and in the sides of a glass tube. If adhesion is stronger than cohesion, the contents of the tube will be pulled upward. This process continues until the adhesive force is balanced by the weight of the water in the tube.

This characteristics of water are a consequence of a particularly strong type of intermolecular attraction, called the hydrogen bond, which is a special type of dipole-dipole interaction between the hydrogen atom in a polar bond, such as N-H, O-H, or F-H, and an electronegative O, N, or F atom.

During the transamination process, the enzyme transaminases uses ________ as a cofactor.

s344n2d4d5 [400]

During the transamination process, the enzyme transaminases use Pyridoxal pyrophosphate as a cofactor.

All transamination reactions, as well as several amino acid oxylation and deamination processes, involve the coenzyme pyridoxal phosphate. The aminotransferase enzyme's epsilon-amino group of a particular lysine group forms a Schiff-base bond with the aldehyde group of pyridoxal phosphate.

The epsilon-amino group of the lysine residue in the active site is replaced by the alpha-amino group of the amino acid substrate. The ensuing intermediate, a quinoid, undergoes deprotonation to become an aldimine, which is then protonated to become a ketimine by accepting a proton in a different position. Ketamine undergoes hydrolysis, leaving the amino group on the protein complex intact.
