T = F × r × sinθ
T - torque
F - linear force
r - distance measured from the axis of rotation to where the application of linear force takes place

Cells correct error in their DNA by three processes: proofreading (errors that occur during replication are rectified), mismatch repair (the mismatched base pairs are corrected just after the DNA replication), and damage repair mechanisms (including direct reversal by cell enzymes, excision repair by replacement or removal of the wrong base, and double stranded base repair by repairing the breaks in the DNA by homologous or non-homologous recombination methods). Pick according to this answer >)
Answer: Thus 293 moles of Oxygen gas can be stored in a standard gas cylinder at a temperature of
and a pressure of 15200 kPa
Explanation:
According to ideal gas equation:

P = pressure of gas = 15200 kPa =150 atm (1kPa=0.0098atm)
V = Volume of gas = 47 L
n = number of moles = ?
R = gas constant =
T =temperature =


Thus 293 moles of Oxygen gas can be stored in a standard gas cylinder at a temperature of
and a pressure of 15200 kPa
Answer:
The enthalpy change for the solution process
= - 158.34 kJ/mol
Explanation:
Given that:
The mass of salt AX = 2.499 g
The mass of water = 135.3 g
The mass of the solution = ( 2.499 + 135.3 ) g = 137.799 g
The specific heat of salt solution s is known to be = 4.18 J/g° C
The change in temperature i.e. ΔT = 35.2 °C - 23.6 °C = 11.6 °C
Thus, the amount of heat raised is equal to the heat absorbed by the calorimeter.
∴





Recall that the mass of the salt = 2.499 g
The number of moles of the salt = 
= 0.0422 mol of AX
Finally the enthalpy change, 
= - 158.34 kJ/mol
The enthalpy change for the solution process
= - 158.34 kJ/mol
