Fe(NO3)2 not sure how to get the oxidation numbers of all elements

Chemistry
1 answer:
Cloud [144]3 years ago
3 0
<span>Fe(NO3)2
The NO3 part is a poly-atomic ion with total charge -1.
This is because Fe has a +2 charge and two NO3's with a -1 charge will balance out to 0.
 Most often we just make the assumption that Oxygen has a -2 oxidation number because it is very electro-negative.
So to find N, we just need an oxidation number that balances out with 3(-2) to get -1 (the total charge of the ion)</span>

How much of a 24-gram sample of Radium-226 will remain unchanged at the end of three half-life periods?
shutvik [7]

Answer:

The right answer is "3 g".

Explanation:

Given:

Initial mass substance,

M_0=24 \ g

By using the relation between half lives and amount of substances will be:

⇒ M=\frac{M_0}{2^n}

        =\frac{24}{2^3}

        =3 \ g

Thus, the above is the correct answer.

A prion is an infectious self-reproducing protein structure. true or false
Alexandra [31]

Answer:

True is the correct answer.

Explanation:

  • The statement that a prion is an infectious, self-reproducing protein structure is true.
  • prion is an infectious particle and they do not have genetic material.
  • Prion present in the brain region that results in deadly neurodegenerative illnesses in humans and animals.
  • Prions are the self-producing proteinaceous infectious capable of transferring infection in the absence of the nucleic acids.
  • prions enter in the brain by an infection and they emerge from the variation in the gene that encodes the protein and once the prions present in the brain multiply by causing the benign proteins to refold into an abnormal form.
