Answer : The correct answer is option 2 : 0.10 M NaCl and 0.10 M NaClO₄
Explanation :
Solutions are classified into 3 categories.
1) Strong electrolytes : These are the solutions that dissociate completely forming ions . They are good conductors of electricity.
Example : All strong acids, bases and the salts made by strong acid/base are strong electrolytes .
2) Weak electrolytes : These substances do not dissociate completely thereby forming fewer ions. They are weak conductors of electricity.
3) Non electrolytes : These are the substances that do not dissociate at all. They do not form ions in aqueous medium. They are bad conductors of electricity.
Let us take a look at the given options and find out what type of solution do we have .
Option 1 : NH₃ is a weak electrolyte whereas NH₄Cl is a strong electrolyte bcause NH₄Cl is made by combination of NH₃ and HCl ( HCl is a strong acid)
Therefore NH₃ would carry electricity less efficiently than NH₄Cl.
Option 2 : Both NaCl and NaClO₄ are strong electrolytes. Therefore they will conduct electrical current equally well
Option 3 : NaNO₃ is a strong electrolyte but HNO₂ is a weak electrolyte. Therefore they will not carry the current equally
Therefore the correct option is option 2
<u>Answer:</u> The total pressure of the container is 140.2416 kPa
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the total pressure, we use the law given by Dalton, which is:
We are given:
Vapor pressure of hydrogen gas, 
= 78 kPa
Vapor pressure of oxygen gas, 
= 2.4416 kPa
Vapor pressure of nitrogen gas, 
= 59.8 kPa
Putting values in above equation, we get:
Hence, the total pressure of the container is 140.2416 kPa
Answer:
The answer of your question is A
Hello!
The potential energy means it causes the object to slow down on the ramp. Potential energy generally means to slow an object.
Thank You!
The pH of a solution is calculated as pH = -log[H+], where [H+] is the concentration of H+ ions. Based on the given concentration in the problem,
pH = -log(1.87 x 10^-13 M) = 12.73
Therefore, the pH of the solution is 12.73, and this implies a strongly basic solution.
