<span>The effective method for separating a mixture of alcohol and water is the
Distillation
</span> By this you only get about 70% alcohol 30% water
As they are <span>azeotropes and cannot be distilled further
so correct option is B
hope it helps

Answer: 1. The coefficient is 1.12
2. The exponent is 4
3. There are 3 significant digits
4. The rightmost significant figure is 2.
Explanation:
Scientific notation is defined as the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.
For example : 5000 is written as 
According to avogadro's law, 1 mole of every gas contains avogadro's number 
of particles and occupy 22.4 L at STP.
molecules of 
occupy = 22.4 L at STP.
Thus 
molecules of occupy = 
at STP.
Scientific notation = 
The coefficient is 1.12
The exponent is 4
There are 3 significant digits
The rightmost significant figure is 2.
Answer:
By breaking down glucose into an energy molecule (ATP), so by producing energy which is necessary for the cell's survival.
Explanation:
Can't help you on 1-4...I'm not very good with energy transformations.
5. coal, oil/petroleum, natural gas; water, wind, plant (there's a name for energy sources coming from plants, but I can't remember it)
6. Metals are lustrous, malleable, and good conductors of heat. Nonmetals are dull, brittle, and poor conductors of heat.
7. Crust is solid, mantle is solid, outer core is liquid, inner core is solid.
8. Millimeters, centimeters, meters, kilometers, milliliters, liters...that's all I can think of.
9. Gravity is the force that pulls objects towards the center of something. Earth's gravity keeps us all on the ground.
10. Anything that causes an object to move.
11. Mass is how much stuff is in something; weight is how heavy something is.
12. Pangaea
13. It's the biggest celestial body in our solar system.
14. A comet is gas and dust that shoot through the sky. (I'm really not sure; I just know it's made of gas and dust)
15. ???
16. ???
17. Insurgent and Allegiant plates xD Divergent plates can form subduction zones and rift valleys.
18. about 5 billion years
19. hydrogen and helium
Answer:
100°C
Explanation:
The higher temperature causes the molecules to increase in speed, and kinetic energy is greatest in the gas phase.
