Which of the following is the best way to separate two liquids? decanting boiling filtering distilling

ITS D. DISTILLING

1. ethanol and water can be seperated by distilling which basically heating it until the ethanol vaporizes

2. trust me im right i took the test

The energy needed to raise the temperature 18.0 grams of water is from 10.0°C to 40.0°C is 2,257.2 Joules.

Explanation:

Where:

Q = heat absorbed  or heat lost

c = specific heat of substance

m = Mass of the substance

ΔT = change in temperature of the substance

: Initial and final temperature of the substance

We have mass of water = m = 18.0 g

Specific heat of water= c = 4.18 J/g°C

Initial and final temperature of the water=

Final temperature of the water=

Heat absorbed by the water:

The energy needed to raise the temperature 18.0 grams of water is from 10.0°C to 40.0°C is 2,257.2 Joules.
