Q4: Ethanol has a boiling point of 78°C. Water has a boiling point of 100°C. Describe how distillation is used to separate a mixture of ethanol and water.

Explanation:

A mixture of ethanol and water can easily be separated by distillation. Distillation separation technique utilizes the differences in boiling point of a mixture of two liquids.

Since water has a higher boiling point compared to alcohol, it makes it easier for the process of distillation to occur

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
