In basic solution hydrogen peroxide oxidizes chromite ions,
Cr(OH)4- to chromate ions, CrO4^2-. The hydrogen peroxide is
reduced to hydroxide ions. Write and balance the net ionic equation
for this reaction. What is the sum of the reactant
coefficients?
What is the concentration of hydrogen peroxide in run #1 when I
add 10.0 ml of 3% of hydrogen peroxide and 35.0 ml of dI water and
15.0 ml of 0.10 M KI?
What is the concentration of hydrogen peroxide in run #2 when I
add 20.0 ml of 3% of hydrogen peroxide and 25.0 ml of dI water and
15.0 ml of 0.10 M KI?
When researches incubate whole red blood cells with
lactoperoxidase, hydrogen peroxide and radioactive iodine I 125 and
then separate the proteins in SDS gel, several radioactive lines
are obtained cause iodine binds to prominent tyrosine and histidine
residues outside the cell membrane.
When researches incubate whole red blood cells with galactose
oxidase and reduce them with sodium borohydride that contains
tritium (H-BH43) several radioactive lines are obtained which are
just some of the proteins that have been marked with radioactive...

What type of genome alterations result in pandemic strains?
4. When was influenza virus discovered and what was known about
it in 1918?
5. From where do most experts think that the influenza virus of
1918-1919 originated, and how was it passed to humans?
A hydrogen atom emits a photon when its electron falls from its
3rd excited state (?=4) to its first excited state (?=2).
Another electron in a box with sides of infinite potential
absorbs the photon and jumps from the ground state (?=1) to the 5th
excited state (?=6).
a. [2] What is the wavelength of the
emitted photon? (Calculate this, don’t just look it up)
b. [3] What is the length of the
box?
c. [3] Using the fact that...
