Answer:
1200 mL
Explanation:
Given data
- Initial pressure (P₁): 600.0 mmHg
- Initial volume (V₁): 400.0 mL
- Final pressure (P₂): 200.0 mmHg
For a gaseous sample, there is an inverse relationship between the pressure and the volume. If we consider the gas as an ideal gas, we can find the final volume using Boyle's law.
![P_1 \times V_1 = P_2 \times V_2\\V_2 = \frac{P_1 \times V_1}{P_2} = \frac{600.0mmHg \times 400.0mL}{200.0mmHg}=1200 mL](https://tex.z-dn.net/?f=P_1%20%5Ctimes%20V_1%20%3D%20P_2%20%5Ctimes%20V_2%5C%5CV_2%20%3D%20%5Cfrac%7BP_1%20%5Ctimes%20V_1%7D%7BP_2%7D%20%3D%20%5Cfrac%7B600.0mmHg%20%5Ctimes%20400.0mL%7D%7B200.0mmHg%7D%3D1200%20mL)

Explanation:
basically a mixture
Answer: Therefore, the volume of a 0.155 M potassium hydroxide solution is 56.0 ml
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
where,
= molarity of
solution = 0.338 M
= volume of
solution = 25.7 ml
= molarity of
solution = 0.155 M
= volume of
solution = ?
= valency of
= 1
= valency of
= 1
Therefore, the volume of a 0.155 M potassium hydroxide solution is 56.0 ml
You should be careful to remember that iodine and fluorine cannot be introduced into an aromatic ring by the method used for bromine and chlorine. On its own, iodine is unreactive with aromatic rings, but one method for aromatic iodination is treatment in the presence of a copper salt such as copper(II)chloride where I2 is oxidized to the more electrophilic species I+.
