3rd Law of Thermodynamics

The correct answer is the third law of thermodynamics.

"The entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 K).”

The temperature scale they refer to is the zero in kelvin degrees, this is what we call absolute zero.

If the entropy is zero, all physic processes stop, and the entropy of the system is minimum and constant.

Given its reactive nature, oxygen is essential to cellular metabolic reactions. Peroxisomes use oxygen to break down fatty acids
marysya [2.9K]

Answer:

Catalase

Explanation:

These reactive oxygen specie or free radicals that cause damage or injury to cells also lead to oxidative stress if unchecked by antioxidants. As suggested in the question, there are several enzymes that act as antioxidants in mitigating the effects of these reactive oxygen specie or free radicals. These enzymes include catalase, superoxide dismutase and glutathiones (such as glutathione s-transferase).

The enzyme that however prevents the accumulation of hydrogen peroxide (H₂O₂) in the peroxisome is catalase. Catalase is an enzyme that is present in the peroxisome; it (catalase) detoxifies/acts on H₂O₂, converting it (H₂O₂) into water and oxygen.

Neils Bohr published his model of the atomic structure in 1913. He introduced the theory of electrons traveling in orbits around
Effectus [21]

Answer:

The number of atoms in the outermost shell  

Explanation:

For example, the electron shells in the alkali metals contain the following numbers of electrons:

 Li: 2, 1

Na: 2, 8, 1

 K: 2, 8, 8, 1

They all have one electron in their outermost shell, and they have similar chemical properties.

Explain Charles law​
kodGreya [7K]

"Charles Law" is the relationship between "volume-temperature" (V ∝ T).

<u>Explanation</u>:  

Charles Law is basically volume-temperature relationship (V ∝ T). French scientist “Jacques Charles” in 1787 studied effect of temperature on the volume of gases at constant pressure, which described how gases manage to expand when heated. Law stated as “At constant pressure, the volume of a given "mass" of a gas decreases or increases by 1/273 of its volume at 0^{\circ} \mathrm{C} for each one degree rise or fall in temperature”. Formula derived from law is as follows: \mathbf{V}_{\mathbf{t}}=\mathbf{V}_{0}[\mathbf{1}+\mathbf{t} / \mathbf{2} 7 \mathbf{3}] here {V}_{0} is volume of given mass of a gas at 0^{\circ} \mathrm{C}, {V}_{t} is its volume at any temperature t^{\circ} \mathrm{C}. Application of Charles law is hot air balloons.

What is the volume that you should dilute 30mL of a 12.0M H2SO4 solution to obtain a 0.160M H2SO4 solution?
shutvik [7]
To solve this problem, the dilution equation (M1 x V1 = M2 X V2) must be used. The given values in the problem are M1= 12.0 M, V1= 30 mL, and M2= 0.160 M. To solve for V2,
V2=M1xV1/M2
V2= (12x30)/0.16
V2= 2,250 mL.
The correct answer is 2.25 L.
