_____has particles with the greatest average kinetic energy

OLEGan [10]

Answer:

c warm water

Explanation:

Kinetic energy is related to temperature. The molecules in a glass of warm water have more kinetic energy (they move faster – see Racing Molecules) than the molecules in a glass of cold water. The temperature of a substance is the average* amount of kinetic energy its molecules have.

The ir spectrum of benzilic acid is shown below. for each peak indicated by the blue boxes, select the bond represented by the f

Bess [88]

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
