Answer:
68 grams
Explanation:
Reaction that produces ammonia when nitrogen and hydrogen reacts is given by :-
+ 3
→ 2N
Clearly ,
When one mole of nitrogen reacts , two moles of ammonia will be produced.
Now,
weight of 1 mole of the Nitrogen = 28.0 grams
In 56.0 grams of the nitrogen , two moles will be present.
Thus , 4 moles of ammonia will be produced .
Weight of one mole of nitrogen = 17 grams.
Thus a total of 17× 4 = 68 grams f nitrogen will be produced.
The two particles that account for the mass of an atom are protons and neutrons. Electrons on the other hand are negligible mass, and so light they are considered without weight.
The Roman numerals in a cation's name indicate: THE POSITIVE CHARGE ON THE CATION
Cations are metallic atoms that loosely hold it electrons, making it easy to lose electrons.
The Roman numerals in a cation's name not only indicates the charge on the cation but it makes it easier to distinguish cations that share the same metal name.
<u>Answer:</u> The number of atoms of plutonium present in given number of moles are ![3.7\times 10^{24}](https://tex.z-dn.net/?f=3.7%5Ctimes%2010%5E%7B24%7D)
<u>Explanation:</u>
We are given:
Number of moles of plutonium metal = 6.1 moles
According to mole concept:
1 mole of an element contains
number of atoms.
So, 6.1 moles of plutonium will contain =
number of plutonium atoms.
Hence, the number of atoms of plutonium present in given number of moles are ![3.7\times 10^{24}](https://tex.z-dn.net/?f=3.7%5Ctimes%2010%5E%7B24%7D)
