Explanation:
As the total concentration is given as 1.2 mM. And, it is also given that salt present in the solution is NaCl.
As sodium chloride is an ionic compound so, when it is added to water then it will dissociate into sodium and chlorine ions as follows.
So, it means in total there will be formation of 2 ions when one molecules of NaCl dissociates.
Therefore, concentration of chlorine ions will be calculated as follows.
Concentration of 
ions = 
= 0.6 mM
Thus, we can conclude that the concentration of chloride ions is 0.6 mM.
Answer:
3.75 L
Explanation:
We can solve this problem by using <em>Charles' law</em>, which states:
Where subscript 1 stands for initial volume and temperature and subscript 2 for final volume and temperature, meaning that in this case:
We <u>input the data</u>:
- 2.5 L * 300 K = V₂ * 200 K
And <u>solve for V₂</u>:
Answer:
true
Explanation:
energy is the energy to do things
and there is a force in our bodies wich is giving out energy through a distance
Number
The atomic number is the number of protons in one atom of an element.
Hope this helps!
Answer: The volume is 57.52 mL if the temperature if raised to 343K.
Explanation:
Given: 
= 27 mL, 
= 161 K
= ?, 
= 343 K
According to Charles law, at constant pressure the volume of an ideal gas is directly proportional to temperature.
Formula used is as follows.
Thus, we can conclude that volume is 57.52 mL if the temperature if raised to 343K.
