The answer would be letter b
[Ne]3s^23p^6 ( answer D) represent a sample of an octet. Octet is the tendency of an atom to have eight electrons in the valence shell. [Ne]3s^2 3p^6 is an octet since its valence electron that is3s^23p^6 has eight electrons.
Answer: Options related to your question is missing below are the missing options
a. cytochrome c is a one-electron acceptor, whereas QH2 is a two-electron donor.
b. cytochrome c is a two-electron acceptor, whereas QH2 is a one-electron donor.
c. cytochrome c is water soluble and operates between the inner and outer mitochondrial membranes
d. heart muscle has a high rate of oxidative metabolism, and therefore requires twice as much cytochrome c as QH2 for electron transfer to proceed normally.
e. two molecules of cytochrome c must first combine physically before they are catalytically active.
answer:
cytochrome c is a one-electron acceptor, whereas QH2 is a two-electron donor. ( A )
Explanation:
The overall stoichiometry of the reaction requires 2 mol of cytochrome per mole of QH2 because a cytochrome is simply a one-electron acceptor while QH2 is not a one-electron donor ( i.e. it is a two-electron donor )
An electron donor in a reaction is considered a reducing agent because it donates its electrons to another compound thereby self oxidizing itself in the process.
The answer is (3) neutrons and protons. The nucleus of an atom is composed of neutrons and protons. There is only one atom nucleus composed of only protons, Hydrogen. And the electrons are moving in high speed around the nucleus.
Percent composition is mass of element over mass of compound times 100. 6.41 + 9.60 = 16.01 g of compound, so % composition of sulfur is 6.41/16.01 x100 or 40.0%. % oxygen is 9.60/16.01 x 100 or 60.0%.
