A flask contains a gas mixture of hydrogen and nitrogen. The total pressure of the mix is 2.0 atm. The partial pressure of the h
1 answer:
Answer:
Explanation:
Hello,
In this case, considering the Dalton's law states that the total pressure of a system equals to the summation of all the pressures of the gases in the system as shown below:
In such a way, for the given system, we've got:
Finally, solving for the partial pressure of nitrogen, we obtain:
Best regards.

Answer: Option (b) is the correct answer.
Explanation:
When there are more number of hydroxide ions in a solution then there will be high concentration of or hydroxide ions. As a result, more will be the strength of base in that particular solution.
A base is strong when it readily dissociate into its ions in the solution. When a base is strong, then it does not matter at what concentration it is dissolved in the solution because despite of its low concentration it will remain a strong base.
Thus, we can conclude that out of the given options, the statement even at low concentrations, a strong base is strong best relates the strength and concentration of a base.
