To determine which equation correctly represents the combined gas law, let's analyze each of the given options:
1. PIV-PV: This expression is not structured in a way that aligns with any known gas laws. It doesn't resemble a valid gas law equation or any standard mathematical form we use in chemistry.
2. PV PV 20: This expression is ambiguous and lacks the structural clarity of a proper equation. It does not make sense as a formula representing the combined gas law.
3. PAVATA-P2V2: This expression is also incorrect. It does not match the form of any known standard gas law equation.
Therefore, after analyzing these options, none of them represent the combined gas law correctly. The correct form of the combined gas law is:
[tex]\[ \frac{P1 \times V1}{T1} = \frac{P2 \times V2}{T2} \][/tex]
Given this, it is clear that none of the options provided are correct representations of the combined gas law.
Hence the solution to the question is:
0
