7.01 is the answer of the [H+] of a solution with a pH of 4.78
423 psi
Hope this helps and GOOD LUCKKK :)))
As per Le Chatelier principle, when a system in equilibrium is disturbed, the reaction will try to compensate the change to restore the equilibrium.
This reaction occurs in gas phase, so the volume is inversely proportional to the pressure.
Then a decrease in volume will cause an increase in pressure, so the system will tend to react in the direction that compensates this increase, this is the system will try to reduce the number of moles of particles to reduce the increase of the pressure.
As you see, there are 3 particles of products (2 of NO and 1 of Br) for every 2 particles of reactant (NOBr).
That means, that the equilibrium will displace to the left, this is the concentration of NOBr will increase while the concentration of NO and Br will decrease.
Answer:
The temperature of the cold water is lower than the warm one. So, when we put the hand in the warm from the cold water, our hand will absorb heat, causing the hand to feel hot. Thus, we can conclude that the more heat it absorbs, the more hotter it is. Whereas the more heat it releases, the colder it is.
Since the pH of the substance is 5, the substance contains more of hydrogen ions.
<h3>What is pH of a solution?</h3>
The pH of a a solution is the negative logarithm to base ten of the hydrogen ions concentration of the solution.
![pH = -log[H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5BH%5E%7B%2B%7D%5D)
A neural solution has pH 7.
A solution with pH below 7 has more hydrogen ions while a solution with pH above 7 has more hydroxide ions.
The pH of a substance contains a hydrogen ion concentration of 1.0 x 10-5 M is 5.
Therefore, the substance contains more of hydrogen ions.
