This absolute amount of pressure does not play a significant difference.
At high temperatures and low pressures, its results deviate too little.
But at low temperatures and high pressures, it will change significantly and this difference will change from gas to gas.
In the image you can see the difference between some results from both equations.
Answer : To calculate the standard molar enthalpy of complete combustion of liquid ethanol can be done by using the formula given below;

Now, the enthalpies of the elements in their standard state is zero always.
So the

Here we can avoid the heat of enthalpy of oxygen,carbon dioxide and water as they exists in their standard states.
So the

=
Answer:
The box will move towards me by the additional force of 60N.
Explanation:
I am pulling the box with a force of 30N and my friend is pushing the box in the same direction with a force of 30N.
Here two forces are exhibited in the same direction that is towards myself as a result the box will move towards me by an additional force of 30N+30N=60N.
A. Is not possible.
The pH scale runs from 0 to 14
