Based on the passage, what is the structure of the product of the reaction between 8-hydroxyquinoline-5 sulfonate and hrp?.

1 answer:

4 0

A because the end result of this reaction is a radical created by the oxidation of an aromatic amine's or phenol's ring substituent. The hydroxyl group of a phenol acts as the ring substituent in this situation.

<h3>Which two enzyme types are required for the two-step process of converting cytosine to 5 hmC?</h3>

The methyl group is transferred to cytosine in the first stage, and it is then hydroxylated in the second step.
Therefore, a transferase and an oxidoreductase are the two groups of enzymes required.

<h3>Which kind of interaction between proteins and the dextran column material is most likely to take place?</h3>

Hydrogen bonding because the glucose's OH would form an H-bond with any exposed polar side chains on a protein surface.

<h3>Two out of the four proteins would adhere to a cation-exchange column at what buffer pH? </h3>

Only positively charged proteins can bind to a cation-exchange column, and this can only happen when the pH is lower than the pI.
Proteins A and B would both be positively charged at pH 7.0.

How many moles of MgO are produced when .250 mol of Mg reacts completely with O2

nignag [31]

Answer:

0.250 moles of MgO are produced when 0.250 mol of Mg reacts completely with O₂

Explanation:

In first place, the balanced reaction between Mg and O₂ is:

2 Mg + O₂ ⇒ 2 MgO

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of reactants and products participate in the reaction:

Mg: 2 moles
O₂: 1 mole
MgO: 2 moles

Then you can apply the following rule of three: if by reaction stoichiometry 2 moles of Mg produce 2 moles of MgO, 0.250 moles of Mg, how many moles of MgO will they form?

$moles of MgO=\frac{0.250 moles of Mg*2 moles of MgO}{2 moles of Mg}$

moles of MgO= 0.250

<u><em>0.250 moles of MgO are produced when 0.250 mol of Mg reacts completely with O₂</em></u>

What has the lowest ionization erergy?

Svetach [21]

Answer:

Francium (Fr)

Explanation:

From the given choices, francium will have the lowest ionization energy.

Ionization energy is the energy required to remove the most loosely held electron within an atom.

The magnitude of the ionization energy depends on the characteristics of the atom in relation to its nuclear charge, atomic radius, stability etc.

Generally on the periodic table, ionization energy increases from left to right on the table
As you go from metals to non-metals and to gases, the value of the ionization energy increases steadily.
Down the group, the value reduces.
Since Francium is the most metallic of all the given choices, it has the highest ionization energy.
