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.
Explanation:
Thunderstorms, warm ocean water and light wind are needed for a hurricane to form (A). Once formed, a hurricane consists of huge rotating rain bands with a center of clear skies called the eye which is surrounded by the fast winds of the eyewall (B).
The balanced chemical equation that illustrates this reaction is:
<span>C2H4 + 3O2 --> 2CO2 + 2H2O
</span>
From the periodic table:
mass of carbon = 12 grams
mass of hydrogen = 1 gram
Therefore:
molar mass of C2H4 = 12(2) + 4(1) = 24 + 4 = 28 grams
number of moles = mass / molar mass
number of moles of C2H4 = 54.7 / 28 = 1.95 moles
From the balanced equation above:
3 moles of oxygen are required to react with one mole of C2H4, therefore, to know the number of moles required to react with 1.95 moles of C2H4, all you have to do is cross multiplication as follows:
number of oxygen moles = (1.95*3) / 1 = 5.85 moles
