This is generally true, though if either the acid or base (or both) is a weak base, the reaction may not go to completion and the properties of the mixture may be more complicated.
The significance of the point where the pressure drops to zero is that at that point the gases would completely show ideal behavior.
<h3>What is the gas law?</h3>
The gas laws can be used to describe the behavior of the ideal gases. It is pertinent to note that the ideal gas law can strictly be applied to gases that are at a high temperature and low pressure.
We can be able to find the temperature when the pressure is equal to zero either be the use of the equation line or by experiment. In that case, we would be able to obtain the point at which the pressure drops to zero.

Answer:
60
Explanation:
there's 5 lines, and 800-700=100 each line represents 20 because 20×5=100.
from a to b, there's 3 lines and 3×20=60
Answer:
<u>∆H° reaction = -890.3 kJ</u>
Explanation:
The given equation is :
Now ,
O2 is in the standard state so its ∆H° is zero.
∆H° is calculated by considering the formation of CO2 , H2O and CH4 .
..........∆H°a = -393.5 kJ
.....∆H°b = -285.8 kJ
..........∆H°c = -74.8 kJ
Multiply equation of water H2O by 2
and reverse the direction of equation of CH4
Hence the sign of ∆H°c = +74.8 kJ becomes +ve.
We are doing this because CH4 is to be in the reactant side not in the product side.
∆H° reaction = ∆H°a +2(∆H°b) -∆H°c
∆H° reaction = -393.5 - 2(285.8) + 74.8
∆H° reaction = -890.3 kJ
Rusting of iron is the most familiar example of corrosion. It is a process in which an iron reacts with atmospheric oxygen and moisture to form a reddish brown substance iron oxide, which is commonly known as rust.
