Answer:Astrobiology, formerly known as exobiology, is an interdisciplinary scientific field concerned with the origins, early evolution, distribution, and future of life in the universe.
Explanation:
Answer:
The heat of solution is 1.05 kJ/mol
Explanation:
NaOH → Molar mass 40 g/m
This is the mass in 1 mol
Calorimetry formula:
Q = m . c . ΔT
ΔT = T° final - T° initial = 24.5°C - 18.2°C = 6.3°C
mass = 40 g
c = 4.186 kJ/kg°C (the same as water)
So we have to convert 40 g to kg
40 g/1000 = 0.04 kg
Q = 0.04 kg . 4.186 kJ/kg°C . 6.3 °C = 1.05 kJ

Answer: 336.2K
Explanation:
The boiling point is obtained from the standard enthalpy and entropy of vaporization as shown in the image attached.
Standard enthalpy of vaporization=35.3KJmol-1=35.3×10^3 Jmol-1
Standard entropy of vaporization= 105 JMol-1K-1
The formula and details of the solution are shown in the image attached.
