Equilibrium is a state of balance or a stable situation where the opposing forces cancel each other out and where no changes are occurring.
<h3>How to explain the equilibrium?</h3>
Your information is incomplete. Therefore, an overview will be given. In a chemical reaction, chemical equilibrium is a state where the reactants and products are present in concentrations that have no further tendency to change with time.
In terms of volume changes within a system at equilibrium, the following applies:
- When there is a decrease in volume, then the equilibrium will shift to favor the direction that produces fewer moles of gas.
- When there is an increase in volume, then the equilibrium will shift to favor the direction that produces more moles of gas.
In conclusion, if you increase the pressure of a system at equilibrium, the stress will be reduced by reaction that favors the side with the fewest moles of gas.

The spectral line has been defined as the more or less number of photons in the spectrum that appears bright or dark. The electron jumping from n = 4 to 3 belongs to the Paschen series.
<h3>What is the Paschen series?</h3>
The Paschen series is the Infrared (I.R) region that has a number of lines estimating from higher energy levels to n = 3 energy levels. If the electron jumps from n = 4 to n = 3 then they have wavelengths of 1875 nm.
This wavelength has been found to lie in the IR region that emits electrons from the atom of hydrogen. The electron tends to move from higher energy states to lower energy states.
Therefore, the electron transition belongs to the Paschen series.

Answer:
Explanation:
To balance equations try to list out each element on both sides and start with the ones that aren't equal
B. The nucleus of an atom contains protons and neutrons.
<span>V = 150.0 mL = 0.15 L
c = 1.70 M
</span>m=?
For the purpose, the equation for molar concentration is necessary:
c=n/V
From the equation we can determine the number of moles:
n= cxV = 1.70M x 0.15L = 0.255 mole
Now we can calculate the mass:
m = nxM = 0.255 x 119= 30.34 g is necessary
