Choice A

Option A is the correct response because carboxylic acids have the CARBOXYL GROUP (-COOH) as their functional group.

is accurate since symmetrical ketones always result in a mixture of two carboxylic acids and only one carbon atom next to the carbonyl group is oxidized. This is written in PTB as well.

Reactions that need heat or energy from the environment are known as endothermic reactions.When an endothermic reaction takes place, the system’s temperature drops below its starting point as the heat needed for the reaction is extracted from the reacting elements. As heat is drawn in from the environment, the system’s temperature eventually returns to room temperature. They are sometimes referred to as endergonic or devouring responses.

A saturated solution can be cooled to produce crystals. When a saturated solution cools, the solute molecules begin to crystallize because they are unable to remain dissolved in the solvent. Until the solution is no longer saturated, the crystals will keep growing.

Ion-dipole forces are the forces that exist between ions and molecules of water.

A theoretical model known as the kinetic theory of gases uses a large number of submicroscopic particles, such as atoms and molecules, to describe the molecular makeup of the gas. The theory also explains how particles colliding with the container walls and one another cause gas pressure. In addition to defining transport properties like viscosity and thermal conductivity, the kinetic theory of gases also defines properties like temperature, volume, and pressure. It provides an explanation for every property associated with the microscopic phenomenon.

Ar of Na= 23g/mole

Mole = Mass/Mr

Mole = 46/23

Mole = 2mole

1mole => 6.02×10^23 atoms

2mole => x atoms

x= 12.04×10^23 or 1.204×10^24

B is accurate because the side of the equilibrium favoring the endothermic reaction will be preferred in order to absorb the additional heat produced by an increase in temperature.

Lysine’s R-group chain contains the amino acid NH2.

The smallest collection of atoms with the overall symmetry of a crystal is called a “unit cell,” from which the entire lattice can be constructed through three-dimensional repetition.

By using the following reaction equation, butanone is oxidized to yield two molecules of acetic acid:

Because its particles are widely separated, plasma has the weakest intermolecular forces. From solid to liquid to gas to plasma, the intermolecular forces become weaker.

Concentration is directly proportional to mass. This indicates that the rate would increase four times (22) if the concentration of A were doubled. The rate would rise nine times if the concentration of A were tripled (32). In terms of symbols:

Water’s known vapor pressure at 8 degrees Celsius is 8.1 torr.

Since we don’t know the location of absolute Zero, we are unable to determine a substance’s absolute enthalpy. Only enthalpy changes between starting and end states can be measured because this calculation can only be done in relative terms.
