Answer:
Explanation:
The concept of Lewis Acid and base was applied in determining the product formed from the reaction of the lewis acid and the lewis base.
According to G.N Lewis - an american who worked and elaborated more on the definition of acids and bases. He defined an acid as an electron pair acceptor and a base as an electron pair donors.
One of the application of lewis theory is in the reaction to test for the presence of copper(ii) ions by the addition of ammonia to form a clear blue solution of tetraammine.
The reactions of the lewis acid to each of the base is as shown in the attached file.
Boric acid, H3BO3, in aqueous solution would only give out one H+ ion. As it is also produce OH ion and by hydrolysis it produces one proton. <span>All the boron compounds (BX3) are having only 6 valence electrons in it and should follow the octet rule by taking another electron.</span>
B(OH)3 + 2 H2O → B(OH)4− + H3O
Answer:
Direct current!
Explanation:
Process of elimination, it isn't A, it isn't C, and it definitely isn't D
I think the answer is A. Physical weathering, because since a debris is added to the landform, it is physically happening.
Answer:
Explanation:
Since we are not given the mole fraction of ethanol and water; we will solve this theoretically.
Using Raoult's Law:
For water:

where
of water = 12.5 mmHg
Then, the vapor pressure of water:

For ethanol:

and the
of ethanol = 32.1 mmHg
Then, the vapor pressure of ethanol:

The total vapor pressure 
The total vapor pressure =
