Both 2-propanol and water can be separated by the process of distillation because the 2-propanol and water have combined physically and retain their different boiling points. Thus, the correct option for this question is C.
Distillation may be defined as a methodology through which components are separated from a mixture. It involves the process by which the components are evaporated and the vapors condensed.
2-propanol is also known as Isopropyl alcohol. The boiling point of this is 82.5°C which is lower than that of water. When both 2-propanol and water are mixed they usually get separated through the physical process known as boiling. Water typically starts boiling at 100°C.
Therefore, the correct option for this question is C.

3 billion
4 ½ billion
6 ½ billion
Answer is 4 ½ billion.
Scientists think the earth's age is 4 ½ billion. This calculation is based on the radioactive dating. Since the formation of the earth, the time period has been divided into 3 major geological time periods as eon. They are phanerozoic, proterozoic and archean.
Scientists estimate that the Earth is approximately 4.5 billion years old based on radiometric dating and other lines of evidence.
The correct answer is 4 ½ billion years. Scientists believe that the Earth is approximately 4.5 billion years old based on evidence from radiometric dating of rocks on Earth and meteorites. Radioactive elements such as uranium and potassium decay into stable isotopes over time, and by measuring the ratio of parent isotopes to daughter isotopes in rocks, scientists can estimate the age of the Earth.
This estimation is supported by other lines of evidence, such as the age of the oldest rocks on Earth and the Moon, and the ages of meteorites. These findings suggest that the Earth formed shortly after the formation of the Solar System, which is estimated to be about 4.6 billion years old.
Therefore, the most accurate estimation is that the Earth is approximately 4.5 billion years old.
