Answer:
The pressure of 0.5 mole of nitrogen gas=
Given:
Moles of nitrogen gas=0.5mole
Volume of nitrogen gas=5L
Temperature of nitrogen gas=203K
To Find:
Pressure of 0.5g mole of nitrogen gas
<u>Step by Step by Explanation:</u>
Formula used for calculating the pressure of a gas is achieved through ideal gas equation
According to Ideal Gas;
From this above equation, pressure can be calculated as
Where P=Pressure of the gas
N=number of moles=0.5moles
R=Gas constant
V=Volume of nitrogen gas in litres=5L
T=Temperature of nitrogen gas=203K
Substitute all the values in the above equation we get
Result:
Thus the pressure of 0.5 mole of nitrogen gas is <u></u><u>
</u>
Answer:
<h2>D. The variable c</h2><h2>
Explanation:</h2>
Q = total energy,
m = mass
T = temperature change.
Answer:
Option B. The equilibrium of the reaction would shift to the right.
Explanation:
According to Le Chatelier's principle, when an external constrain such as change in concentration, temperature or pressure is imposed on a chemical system in equilibrium, the equilibrium position will shift in order to neutralize the effect.
Now, let us answer the question above.
From the question given above, the equation is:
A + B <===> C + D
Increasing the concentration of A will shift the equilibrium position to the right.
This is true because increasing the concentration of A means having more reactants in the system. So the reactants react to produce more product thereby shifting the equilibrium position to the right.
It is a graph. It shows observations and then you record your results with any of the graph types.
Answer:
The difference between the density of the ocean crust and the continental crust is the fact that the ocean crust is denser than the continental crust. Meaning, the continental crust is likely to push over the oceanic crust considering it has less dense.
