What is the most likely decay for the fe-53 nucleus?

1 answer:

7 0

The element number of Fe is 26, which means that the number of neutrons of the following isotopes is:

53-Fe: 27 
54-Fe: 28 
56-Fe: 30 
57-Fe: 31 
58-Fe: 32 
59-Fe: 33 

Because 53-Fe has too few neutrons when compared to the other isotopes we can rule out any decay that involves losing a neutron: (alpha decay, beta decay) So, this isotope will prefer to decay by electron capture or positron emission (assuming the system has about 1 MeV to spare), but in each case the product will be the same: 53-Mn (long-lived radioisotope).

The equation for the synthesis of ammonia is below. How many moles of H 2 are

kkurt [141]

Moles of H₂ are needed to produce 9.33 moles of NH₃ : 13.995

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

The reaction coefficient in a chemical equation shows the mole ratio of the reactants and products

Reaction for the synthesis of ammonia :

N₂+3H₂⇒2NH₃

moles of NH₃ = 9.33

From equation, mol ratio of H₂ : NH₃ = 3 : 2, so mol H₂ :

$\tt =\dfrac{3}{2}\times 9.33\\\\=13.995$
