In forming a molecular compound, each atom should have ______ electrons around it unless there is some specific reasons why this
ivolga24 [154]

In forming a molecular compound, each atom should have <u>valence</u> electrons around it unless there is some specific reasons why this cannot be achieved.

<h3>What is Valence Electrons ?</h3>

Valence electrons is a negatively charged particle present in the outermost shell of an atom.

Example: Oxygen has 6 valence electrons in its outermost shell, Water has 8 valence electrons.

Thus from the above conclusion we can say that In forming a molecular compound, each atom should have <u>valence</u> electrons around it unless there is some specific reasons why this cannot be achieved.

1. A gas has a volume of 45 L at a pressure of 140 kPa. What is the volume when
pishuonlain [190]

Answer:

The new volume of the gas is 21 L.

Explanation:

Volume of a gas is inversely proportional to its pressure at constant temperature such that,

V\propto \dfrac{1}{P}

or

P_1V_1=P_2V_2

We have,

V_1=45\ L\\\\P_1=140\ kPa \\\\P_2=300\ kPa

It is required to find V₂. Using above law or Boyle's law such that :

V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{140\times 45}{300}\\\\V_2=21\ L

So, the new volume of the gas is 21 L.
