Biochem Module 2 SetWhat is the form of water? - ANSBent. The bond attitude is 104.5 ranges.
What is autoionization, and how is it crucial for water? - ANSAutoionization is the capacity of
a compound to react with itself to form ions. One water molecule reacts with a 2nd molecule
to shape ions: H3O+ and OH-. These ions exist in small quantities in natural water and
influence the chemistry of water.
Name the three non-covalent forces mentioned in this module - ANS1. Dipole-dipole forces,
2. Hydrogen bonding, and 3. London dispersion forces
What sort of non-covalent interplay is known as the most powerful dipole-dipole force? -
ANS.Hydrogen bonds.
Would the following be a hydrogen donor or acceptor? Or both? - ANS.Only a hydrogen
acceptor because of the electrons on the oxygen. It isn't always a hydrogen donor because
the electrons are bonded to a carbon.
How does the energy of London forces alternate with increasing molecular weight? Explain
in short. - ANSAs molecular weight increase, the strength of London forces also increase.
This is due to the multiplied wide variety of electrons in large molecules. The larger quantity
of electrons creates the capacity of stronger temporary dipoles.
Calculate the pH of solution containing 0.12 M of OH-. - ANSpH = 13.08
If an answer contains zero.00023M of H+, then what's the OH- concentration? - ANS4.35 X
10-11 M OH-
If a solution incorporates 1.67 x 10-8 M OH-, then what's H+ concentration? - ANS5.Ninety
nine x 10-7 M H+ or 6 X 10-7M
A solution includes H+ at a attention of 1.Sixty seven x 10-6 M. Is the solution acidic, basic,
or neutral? Explain briefly. - ANSAcidic. The pH = five.Seventy seven, that's acidic. Students
should use the pH scale Table in Module 2 to determine this.
What is the attention, in M, of water as a pure liquid? - ANS55.Five mol/L
Define Keq and Kw. - ANSKeq is the equilibrium steady. Numerically, it's far same to the
concentrations of equilibrium merchandise (in M) elevated collectively over the attention of
equilibrium reactants increased collectively.
Kw is known as the ion product. It is, essentially, the Keq for water this is same to at least
one.Zero x 10-14; the method is:
