What is the Molar Mass of Iron(Fe)? and also state how many particles there are in one mole of iron.

1 answer:

4 0

The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams.

<h3>What is an ionic compound?</h3>

Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.

Barium is a metal element and Nitrogen is a non-metal element, so they form an ionic compound. To make the formula of an ionic compound, first, we need to see the valence of the atoms, that is, how many electrons it can donate or it has to gain to have 8 electrons in the valence layer (octet rule).

Barium is in family 2, so it has two electrons in its valence layer, so it must donate these two electrons; Nitrogen is in family 15, so it has 5 electrons ins its valence layer and must gain 3 electrons.

Writing the ions they must form:

$Ba^{+2}N^{-3}$

First came the cation (positive charge), then the anion (negative charge), and the charges must change between them, without the signal, and will inform how many atoms are necessary for which element:

$Ba_3N_2$

Hence, If $Ba^{+2}$ will reacts with $N^{-3}$ , the formula of the compound formed is $Ba_3N_2$ .

For a given mass the energy released is greatest for a reaction involving...

lukranit [14]

Nuclear fusion

Explanation:

For a given mass, the energy released is greatest for a reaction involving nuclear fusion.

Nuclear reactions generally release far much more energy compared to chemical energy because they involve the interaction between strong nuclear forces. There are two main types of nuclear reactions which are fusion and fission.

Nuclear fusion powers the sun and releases the greatest amount of energy.

In nuclear fusion, light atoms combines to form heavier ones.
The reaction degenerates into chain reaction in which huge amount of energy is released.
This reaction occurs in the core of sun and furnishes the solar system with radiant energy.

How do atoms emit light ?

Stella [2.4K]

Answer:

The frequencies of light that an atom can emit are dependent on states the electrons can be in. When excited, an electron moves to a higher energy level or orbital. When the electron falls back to its ground level the light is emitted.
