The correct answer is the octet rule.

Octet rule states that atoms tend to bond in order to have 8 electrons in their outer most electron orbit achieve stable configurations of noble gases.

When atoms form covalent bonds, they achieve the goal of having 8 electrons by sharing the electrons.

In ionic bond, atom either gain or lose an electron and form ions that have the stable configuration of 8 valence electrons.

Not all atoms follow the octet rule and there are many exceptions and variations.

2.2 liters at 20 degrees Celsius if the pressure doesn’t change what is the new temperature at 2.6 liters

Mamont248 [21]

Based on the question, it is evident that this question rests on the premise of Charle's Law, which essentially states that temperature is proportional to volume once pressure and mass remain constant.

Thus by Charle's Equation: $\frac{ V_{1} }{ T_{1} } = \frac{ V_{2} }{ T_{2} }$

Since the initial volume = 2.2 L; the initial temperature = 20 C; and the final volume = 2.6 L,
then V₁ = 2.2 L; T₁ = 20 C; V₂ = 2.6 L and what we would be
finding is T₂ (the final/new temperature)

Now, $T_{2} = \frac{(V_{2}) (T_{1}) }{V_{1}}$

⇒ $T_{2} = \frac{(2.6 L) (20 ^{o} C) }{2.2 L}$

⇒ $T_{2} = 23.64 ^{o}C$

∴ the new temperature is ≈ 23.6 °C
