A furnace has an advantage over a flame in atomic absorption because it is more sensitive due to the lengthier time the atomized material remains in the optical path.
A process of absorption is what?Absorption in chemistry is the process by which a material that is already present in one state gets assimilated into another substance that is already present in another state (e.g., gases being absorbed by a liquid or liquids being absorbed by a solid).
What in chemistry are adsorption and absorption?Absorption and adsorption have quite different definitions. A liquid can be absorbed by a substance like a sponge, cloth, or filter paper. The absorbent substance absorbs all of the liquid. Adsorption describes the accumulation of single molecules, atoms, or ions on surfaces.

How the structure of molecule affects physical properties?
The structure of a molecule affects its physical properties because the arrangement of the atoms in the molecule determines the type of forces that interact between molecules.
And that forces affect how the molecules move and interact with each other. This, in turn, affects the physical properties of the molecule, such as its melting point, boiling point, polarity, and solubility.
For example, when a molecule has a higher number of non-polar bonds due to symmetrical structures, it will be less polar overall and have fewer attractive forces acting between molecules, resulting in a higher boiling point and lower solubility.
On the other hand, a molecule with a higher number of polar bonds due to asymmetrical structures will be more polar overall, leading to stronger attractive forces acting between molecules, resulting in a lower boiling point and higher solubility.

Alkynes are hydrocarbons with triple carbon-carbon bonds. For molecules with a single triple bond, their typical formula is CnH2n-2 (and no rings).
A number of the same reactions occur in alkynes as in alkenes, but they can react twice due to the existence of two p-bonds inside the triple bond.

Benzene (C6H6) burns in air to produce carbon dioxide and liquid water.The heat released in KJ per gram of the compound reacted with oxygen is -41.83 KJ.
What is heat ?
Heat is the result of the movement of kinetic energy within a material or an item, or from an energy source to a material or an object. Radiation, conduction, and convection are the three mechanisms through which such energy can be transferred.
The movement of minuscule atoms, molecules, or ions in solids, liquids, and gases produces heat energy. From one thing to another, heat energy can be exchanged. Heat is the flow or transfer that occurs as a result of the temperature differential between two objects.
Reaction as follows;
2C6H6 + 15O2 → 12CO2 + 6H2O
2x49.04 2x10 12x-393.5 6x-285.8
= [ 12(-393.5 )+6(-285.8) ] - [ 2(49.04)+(2x10) ]
= - 6936.8 - 98

Explanation:
an unbalanced 16.0 N force is applied to a 2.0 kg mass. what is the acceleration of the mass
The acceleration of the mass is 8.0 m/s² when an unbalanced 16.0 N force is applied to a 2.0 kg mass.
To calculate the acceleration of the mass, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).
We know that the force acting on the object is 16.0 N, and the mass of the object is 2.0 kg. So, we can use the equation to solve for the acceleration:
a = F ÷ m
where, a = acceleration, F = force (16.0 N), m = mass (2.0 kg)
So,
a = 16.0 N ÷ 2.0 kg = 8.0 m/s²
Therefore, the acceleration of the mass is 8.0 m/s²

What is exothermic reaction?Energy is transmitted to or from the surroundings when a chemical reaction occurs. An exothermic reaction occurs when energy is transmitted to the surroundings, and the temperature of the surroundings rises. The term exothermic implies "heating up." As an exothermic process progresses, energy, frequently in the form of heat, is released. An exothermic reaction is one that is chemical in nature and is characterized by the release of energy in the form of heat or light. Matching a light with a matchstick is an example of this sort of reaction in which the release is both heat and light.
Here,
The spontaneity can be determined by the equation as:
ΔG=ΔH−TΔS
If the Gibbs free energy is negative, it gives a spontaneous reaction. Hence, the ΔH must be negative and ΔS must be positive.
If the Gibbs free energy is positive then it will be non-spontaneous. Hence, ΔS must be negative at very high temperature.

The molecular weight of the unknown compound is 80.864g.
Give a definition of freezing point depression.Only the solute's concentration affects freezing point depression; the solute's mass or chemical composition have no bearing. When it's cold outside, salt is often used to prevent ice from forming on roads by lowering the freezing point of water.
Depression in freezing point is Kb x m
T(f) - T = Kb x m
48.1 - 35.8 = 9.8 x m
m = 1.255
m = moles of solute x 1000/mass of solvent
moles of solute x 1000 / 10.0090 = 1.255
moles of solute = 0.0125
moles = mass / molar mass
1.0108 / molar mass = 0.0125
molar mass = 1.0108 / 0.0125

Now, molar concentration is,
[tex]M=\frac{x}{V}[/tex]
[tex]M=\frac{0.0733}{0.352+0.0167}[/tex]
On solving we get,
M=1.41[tex]\frac{mol}{L}[/tex]
