Answer:
Explanation:
fluorine have gained one electron that is why the sign is -1. they both have different number of protons. They have different neutron numbers. F have 10 and O have 8.
hope this helps :)
The most stable electron configuration helium has.
He
A cofactor is an organic or inorganic molecule or ion necessary for proper functioning of some biological catalysts (option E).
<h3>What is a cofactor?</h3>
A cofactor in biochemistry is a molecule that binds to and regulates the activity of a protein.
A cofactor is a metal or coenzyme responsible for the functioning of an enzyme and must be present.
Therefore, a cofactor is an organic or inorganic molecule or ion necessary for proper functioning of some biological catalysts.

Answer:
0.209M
Explanation:
M1V1=M2V2
(28.5 mL)(0.183M)=(25.0mL)(M)
M2= 0.209M

Answer:
B. False
Explanation:
the reaction is
H₂0 + O₂ = H₂O
as addition of oxygen means burning in the system which means heating or energy is necessary for the reactants. SO the reaction is spontaneous and exothermic .
As according to second law of thermodynamics
the change in enthalpy is greater than or equal to zero when the reaction is spontaneous, so enthalpy will increase in the above reaction.
H2 burning in O2 to form H2O (l) is an example of a system where the entropy of the universe increases.
