Answer:
C. 0.4.
Explanation:
<em>∵ mole fraction of acetic acid (X acetic acid) = (no. of moles acetic acid)/(total no. of moles) = (no. of moles acetic acid)/(no. of moles of acetic acid + no. of moles of water).</em>
<em></em>
- no. of moles of acetic acid = 2, no. of moles of water = 3.
- Total no. of moles = no. of moles of acetic acid + no. of moles of water = 2 + 3 = 5.
<em>∴ mole fraction of acetic acid (X acetic acid) = (no. of moles acetic acid)/(total no. of moles) =</em> (2)/(5)<em> = 0.4.</em>

Answer:
H₂O
Explanation:
H₂O is the chemical formula of water.
Water is regarded as a "universal solvent". The reason behind this is the property of the water. Water is a solvent that can dissolve a variety of substances in itself. Any other liquid cannot dissolve the number of substances that the solvent water can. The reason behind being the universal solvent is the chemical composition and physical characteristics of water.
Natural selection requires variation between individuals. Mutations and reproduction increase genetic variation in a population. Natural selection occurs when environmental pressures favor certain traits that are passed on to offspring.
