There are three ways to measure the amount of something in chemistry.

1. There is a simple count which is tabulating the amount of something present.

2. You can measure the mass which is the amount of matter in something.

3. You can measure the volume which is the amount of three dimensional space occupied by a closed surface.

What is the “Island of Stability”?

3241004551 [841]

Answer:

The island of stability is a term from nuclear physics that describes the possibility of elements with particularly stable "magic numbers" of protons and neutrons. This would allow certain isotopes of some transuranic elements to be far more stable than others, that is, decay much more slowly.

Given the reaction: 4NH3 + 502 4NO + 6H2O

Ainat [17]

Answer:

$\frac{4}{5}$ moles

Explanation:

The reaction equation is given as:

4NH₃ + 5O₂ → 4NO + 6H₂O

The number of moles of O₂ that completely reacted is given as 1 mole

To solve this problem, we are going to use a stoichiometric approach from the balanced reaction equation:

5 moles of O₂ will react completely to produce 4 moles of NO

1 mole of O₂ will therefore react to produce x mole of NO

5x = 4

x = $\frac{4}{5}$ moles of NO
