Which of these expressions are correct variations of the Combined Gas Law? P1V1T2 = P2V2T1 both
2 answers:
Answer:
Explanation:
The combined gas law is also known as general gas law and it is the reduction of the ideal gas equation. In the combined gas law, we assume that n= 1
From PV=nRT
= R (constant) if n= 1
∴ 
= 
=

The formula C2H4 can be classified as both a molecular formula
and an empirical formula. The answer is number 4.
Q = ?
Cp = 0.397 J/ºC
Δt = 40.3 - 21.0<span> => 19.3</span><span> ºC</span>
m = 15.2 g
Q = m x Cp x Δt
Q = 15.2 x 0.397 x 19.3
Q ≈ 116.46 J
