Answer:
Explanation:
Hello,
In this case, since the subscripts for both carbon and oxygen are equal, one could assume the following empirical formula:
Which is suitable for formaldehyde or if it is multiplied by 2 (C₂H₄O₂) for acetic acid or ethen-1,2-diol. In such a way, computing the percent composition:
Thus, if at the beginning we just have, the percentages, one could compute moles as:
Whereas based on the initial formula:
The ratio will be:
For all the whole numbers the empirical formula was multiplied by.
Best regards.
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.
Wave A has the shorter wavelength due too the fact that the shorter the wavelength the higher the frequency as they have an inverse relationship.
In monoculture farming , we produce a single species of a livestock or plant in large quantity.
Eventhough it is very effective, producing a mass number of a single organism in an Area will risk of endangering the existence of a specific nutrient ( because that large number of organism is basically eating the same thing)
which lead to societal decision such as the founding of The Livestock conservancy, or other environmental protection organization <span />
Answer:
15.9994 amu
Explanation:
By definition 1 mole of any substance is the mass that contains 1 Avogadro's Number of particle. (=> 6.02 x 10²³ particles/mole).
1 mole Oxy => 15.9994 amu => contains 6.02 x 10²³ particles Oxy /mole
1 mole Sulfur => 32.064 amu => contains 6.02 x 10²³ particles Sulfur /mole
1 mole H₂O => 18 amu => contains 6.02 x 10²³ molecules of water / mole.
