Answer: 2.5L x 1mol/22.4 = 0.112 mol
Explanation:
Answer:
The correct answer will be option-instructions for each specific function
Explanation:
DNA is known as the genetic and heredity material of the organism which provides instructions to the cell to perform functions.
The biochemistry of DNA suggests that the arrangement of different nitrogenous bases controls different functions of the cell as they form proteins through the transcription and translation process.
Therefore, DNA controls the cell and its function by providing instructions to the organelles in the form of proteins and thus, the selected option is the correct answer.
Answer:
(a) Three translational degrees of freedom, 2 rotational degrees. 5 total
Cv = 5/2 R; Cp = 7/2 R
(b) and (c) 6 total degrees of freedom ( 3 translational, 3 rotational)
Cv = 3 R ; Cp = 4R
Explanation:
(a) O₂
Oxygen being a diatomic molecule has three translational degrees of freedom and two rotational degrees of freedom since it can move in the three axis and can rotate around two.
(b) H₂O
This is a polyatomic molecule and it has three translational and three rotational degrees of freedom.
(c) Same as water it has three translational degrees of freedom and three rotational degrees of freedom
To calculate the heat capacities we have to make use of the equipartition theorem which tell us that for each degree of freedom imparts 1/2 R to the heat capacity at constant volume.
(a)
5 total degrees of freedom ⇒ Cv = 5/2 R
Cp ( heat capacity at constant pressure) is determined from the relation
Cp - Cv = R
Cp = 7/2 R for O2 molecule
(b) and (c)
Total degrees of freedom 6
Cv = 3 R
Cp = 4 R
Here we are ignoring any contribution of the vibrational modes to the contribution of the heat capacities
