You are a doctor examining a bone sample taken from a patient with weak bones you find out the bone tissue contains many small p
Contact [7]

The bone tissue contains many small pauses this is most likely caused by osteoporosis.

<h3>What is osteoporosis?</h3>

Osteoporosis is a health condition that weakens bones, making them fragile and more likely to break.

Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture.

Osteoporosis-related fractures most commonly occur in the hip, wrist or spine.

Bone is living tissue that is constantly being broken down and replaced.

Hence, the bone tissue contains many small pauses this is most likely caused by osteoporosis.

Most atoms form compounds by forming octets in their outer shell. what does octet really mean?
Aleksandr [31]
 <span>The </span>octet rule<span> is a chemical </span>rule<span> of thumb that reflects observation that atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.

Why is it not correct/precise to say "a molecule of salt?"
Fynjy0 [20]

It is not correct to say " a molecule of salt " because salt is a compound.

Explanation:

  • As we know a molecular bond is present in each molecule.
  • Salt (NaCl) is considered as a compound because it is made up of two types of elements that are sodium as well as chlorine.
  • On the other hand it is not considered as a molecule as it is not holding an ionic bond.
  • As a result we can name it as an ionic compound. Hence it is not considered as a molecule of salt.

We get 1700 Tonnes of Ammonia every day. How many tonnes of 63% Nitric acid we can get?
jeyben [28]
There are 3 equations involved in manufacturing Nitric Acid from Ammonia. 

First the ammonia is oxidized:
4NH3 + 5O2 = 4NO + 6H2O

Then for the absorption of the nitrogen oxides.
2NO + O2 = N2O4

Lastly, the N2O4 is further oxidized into Nitric acid.
3N2O4 + 2H2O = 4HNO3 + 2NO

Then run stoichiometry through these equations.
The first equation produces roughly 271,722,938 grams of NO
The second equation produces roughly 416,606,944 grams of N2O4
The last equation produces roughly 380,412,294 grams of HNO3 (nitric acid)

Convert the exact number back into tons, and your answer is: <span>419.332775 tons.
</span>
Rounded, I'm going to say that's 419.33 tons.
Hope this helps! :)

Also, it seems that commercially, Nitric Acid is commonly made by bubbling NO2 into water, rather than using ammonia.
