Answer:

The combined law is:

$\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$

See the derivation below.

Explanation:

1. Boyle's law:

$PV=constant\\\\P_1V_1=P_2V_2$

2. Charles' law:

$\dfrac{V}{T}=constant\\\\\\\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}$

3. Gay-Lussac’s law

$\dfrac{P}{T}=constant\\\\\\\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}$

4. Summary:

PV = K

V/T = K'

P/T = K''

Mulitply PV by V/T and P/T

$PV\times \dfrac{V}{T}\times \dfrac{P}{T}=K\times K'\times K''\\\\\\\dfrac{P^2V^2}{T^2}=constant\\\\\\\sqrt{\dfrac{P^2V^2}{T^2}}=\sqrt{constant}\\\\\\\dfrac{PV}{T}=constant$

Thus:

$\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$

Which is the combined law.

Why do we use molecular models to represent atoms?

Bogdan [553]

The molecular model is physical model of the atomic system used to represent molecules and their processes. It is used to understand chemistry and generating and testing hypotheses and it is the most commonly used explicit representation of atoms.
