Explanation:

Atomic number represents the total number of protons present in an atom. On the other hand, atomic mass represents the sum of total number of protons and neutrons present in an atom.

Also, when an atom is neutral then there will be equal number of protons and electrons present in the atom.

Whereas when there is loss of electrons from a neutral atom then it will attain a positive charge and when there is gain of electrons then the atom will attain a negative charge.

For example, atomic number of nitrogen is 7 and in a N^{3-} ion there will be 7 + 3 = 10 electrons and there will be 7 protons.

Hence, we can conclude that the ion N^{3-} has 7 protons and 10 electrons.

The ion N³⁻ is called the azide ion. In its neutral state, it occurs as the element Nitrogen. The atomic number of Nitrogen is 7. When it turns into an anion (negatively charged ion), it gains 3 more electrons. That's why its net charge becomes -3. It means that the protons is still 7, but the electrons are now 10. 

Overall charge = +7 + -10 = -3

13.0 g NaHSO4 is dissolved in water to make a 2.00 L solution what is the molarité
Sati [7]

Answer:

0.054 M

Explanation:

1 mol NaHSO4 -> 120 g

                   x    ->13 g

x= 0.108 mol NaHSO4

M= mol solute/ L solution

M= 0.108 mol NaHSO4/ 2.00L

M= 0.054 M

Calculate the eccentricity of an ellipse. The distance between the foci is 5.2 and the length of the major axis is 20.6.Round of
Dominik [7]

Answer:

The eccentricity of the ellipse is 0.252.

Explanation:

The eccentricity of an ellipse (c), dimensionless, can be determined by means of the following expression:

e = \frac{\bar c}{\bar a} (1)

Where:

\bar c - Distance between the foci, dimensionless.

\bar a - Length of the major axis, dimensionless.

If we know that \bar c = 5.2 and \bar a = 20.6, then the eccentricity of the ellipse is:

e = \frac{5.2}{20.6}

e = 0.252

The eccentricity of the ellipse is 0.252.
