Answer:
You need to heat the mixture to 78.37°C
Explanation:
In distillation, you can separate 2 or more compounds based on their difference in boiling points.
In a mixture of ethanol and water, in theory, you need to heat the mixture to 78.37°C. In this temperature, the ethanol must be evaporated and then condensed in the receiving flask.

A white rabbit would therefore have (ff)
If a trait is recessive, then it can only be expressed if both alleles (individual letters) are recessive (lowercase).
4. True
5. The amplitude of the ripples decreases as the circumference of the circle increases.
<h3>What is a wave?</h3>
A wave is a disturbance that moves energy from one place to another.
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each travelling in a wave-like pattern at the speed of light. Hence, the statement is true.
As the disturbance moves outwards the energy it carries is spread over a larger and larger region called the wavefront. For example, the ripples in the water lie in a circle with an ever-increasing circumference. The amplitude of the ripples decreases as the circumference of the circle increases.
