The mole concept is important in chemistry because 1. it allows us to distinguish between elements and compounds. 2. it provides
Rufina [12.5K]
Answer:
             <span>The mole concept is important in chemistry because, "</span>Atoms and molecules are very small and the mole concept allows us to count atoms and molecules by weighing macroscopic amounts of material".

Explanation:
                   To understand this question lets take an example of Hydrogen atom. Let suppose you need to react Hydrogen with Oxygen. You need exactly Two Hydrogen atoms and one Oxygen atom to form one water molecule.
                  The mass of 1 hydrogen atom is 1.76 × 10⁻²⁴ grams. How will you count the Hydrogen atoms??? How can you measure exactly for 1 Million Hydrogen Atoms???
                   Answer to these questions and Calculations lies in Mole. It is found that 1 Mole of Hydrogen weights exactly 1.008 gram and contains 6.022 × 10²³ atoms. Now, having this reference in hand you can calculate for any number of Hydrogen atoms.

Result:
           So the Mole helps us to zoom a microscopic level to a macroscopic level. :)

Which of the highlighted carbon-oxygen bonds absorbs at a higher wavenumber in an IR spectrum?
skelet666 [1.2K]

Answer:

1. bond in the molecule on the right

Explanation:

CH3CH2-OH

The compound above is an alcohol due to the presence of the OH bond. The wave number of the C - O bond is given as; 1050-1150 cm^-1.

CH3CH__O

The compound above is an aldehyde due to the presence of the CHO bond. The wave number of the C = O  bond is given as; 1740-1720 cm^-1

Comparing both bonds, the C = O bond absorbs at a higher wave number.
