it started moving North 5 m/s
Answer: Option c. Solution A has a lower boiling point than solution B
Explanation:
For solution A, i = 1 means the solution is a non-electrolyte. This clearly indicates that solution A contains covalently bonded compound. Covalently bonded compounds have lower boiling when compared to those of the ionic.
For solution B, i = 2 means the compound is an electrolyte and it forms two ions. From this result, it is very clear that the compound in solution A is an ionic compound. Ionic compounds have higher boiling points than covalent compounds
Therefore, solution A will have a lower boiling point than solution B
A substance that consist of two elements is one IN WHICH THE ELEMENTS ARE CHEMICALLY COMBINED IN A FIXED PROPORTION.A compound is a substance that is made up of two or more elements which have undergone chemical reaction together and their individual properties have been lost during the reaction, thus a compound has properties that are different from those of its constituents elements. Compounds are usually combined in specific fixed ratio.
The answer to that is: F A L SE
The half-reaction are:
Cd ---> Cd(OH)₂
The oxidation number of Cd changed from 0 to +2. So, the number of mol electron transferred here is 2.
NiO(OH) --> Ni(OH)₂
The oxidation number of Cd changed from +3 to +2. So, the number of mol electron transferred here is 1.
Now, the greatest common factor would be 2. So, we use n=2 for the formula for ΔG°. F is Faraday's constant equal to 96,485 J/mol e.
ΔG° = nFE° = (2)(96,485)(1.5) =<em> 289,455 J</em>
