Below is the structure of Benzilic Acid and IR spectrum. First common thumb rule for elucidating IR spectrum is to find a broad and intense signal between 1690-1800 cm⁻¹, If present! Then its for Carbonyl group. Secondly, watch for broad peak around 3400-3600 cm⁻¹, peak at this frequency is given by the -OH (Hydroxyl) group of Alcohols, andthe broadness is due to Association effect (Hydrogen bonding). Third, aif a wide band between 2500-3300 cm⁻¹ is present it shown -OH of carboxylic acid.
Result: Carbony Group = 1640 cm⁻¹
Carboxyl -OH Group = 2950 cm⁻¹
Alcohol -OH = 3400 cm⁻¹
<u>Answer:</u> The element E is Krypton (Kr).
<u>Explanation:</u>
In a nuclear reaction, the total mass and total atomic number remains the same.
The given nuclear reaction follows:
Total mass on reactant side = total mass on product side
75 = A + 0
A = 75
Total atomic number on reactant side = total atomic number on product side
35 = Z + (-1)
Z = 36
The isotopic symbol of element E is 
Hence, the element E is Krypton (Kr).
Conductors are better than insulators to carry electric current because they give the electricity the ability to flow freely throughout circuits. This helps the insulator to do its job of containing the electric charge. Examples of this would be a tv plug - the rubber surrounding the TV plug helps to keep the conductors (wires) in place, thus helping to facilitate an electric charge.
The average kinetic energy and rms speed of N₂ molecules at STP is 
and 
Given,
The average kinetic energy of a molecule is given by, 
where k is the Boltzmann constant and Tis the absolute temperature of the gas.
The rms speed of 
molecules is given by
The average kinetic energy of a gas's particles is inversely related to its temperature. As the gas warms, the particles must travel more quickly since their mass is constant.
The average kinetic energy (K) is equal to one half of the mass (m) of each gas molecule times the RMS speed (vrms) squared.
