Answer:
Increase in pressure
Explanation:
The rise in temperature will increase the pressure of the gas.
The symbol is U and its atomic number is 92
Answer:
The true statements are:
The solution is acidic
The pH of the solution is 14.00 - 10.53.
![10^{-10.53}=[OH^-]](https://tex.z-dn.net/?f=10%5E%7B-10.53%7D%3D%5BOH%5E-%5D)
Explanation:
The pH of the solution is defined as negative logarithm of hydrogen ion concentration present in the solution .
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
- The pH value more 7 means that hydrogen ion concentration is less ,alkaline will be the solution.
- The pH value less 7 means that hydrogen ion concentration is more ,acidic will be the solution.
- The pH value equal to 7 indicates that the solution is neutral.
The pOH of the solution is defined as negative logarithm of hydroxide ion concentration present in the solution .
![pOH=-\log[OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%5BOH%5E-%5D)
The pOH of the solution = 10.53
![10.53=-\log[OH^-]](https://tex.z-dn.net/?f=10.53%3D-%5Clog%5BOH%5E-%5D)
![10^{-10.53}=[OH^-]](https://tex.z-dn.net/?f=10%5E%7B-10.53%7D%3D%5BOH%5E-%5D)
The pH of the solution = ?


Here, the pH of the solution is less than 7 which means that solution acidic.
Answer:
10 L
Explanation:
The only variables are pressure and volume, so we can use Boyle's Law:
p1V1 = p2V2
Data:
p1 = 125 atm; V1 = 4.0 L
p2 = 50 atm; V2 = ?
Calculation:
125 × 4.0 = 50V2
500 = 50 V2
V2 = 500/50 = 10 L
The new volume will be 10 L.
