Answer:
The answer to your question is 14.3 %
Explanation:
Data
volume of ethanol = 50 ml
volume of water = 300 ml
volume percent = ?
Formula
Percent by volume = (volume of solute/volume of solution) x 100
Volume of solute = 50 ml
volume of solution = 300 + 50 = 350
Substitution
Percent by volume = (50/350) x 100
Simplification and result
<u>Percent by volume = 14.3 %</u>
Heat is been absorb allowing particles of the liquid to overcome the vapor pressure
Answer is: A. covalent bonds.
Insulator most likely has covalent bonds, because it must have low electrical conductivity.
1) Substances with covalent bond not conduct an electric current in liquid and solid state, because they not have free ions or electrons.
2) Substances with ionic bond conduct an electric current in liquid, but not in solid state, because in liquids ions are mobile, contrary to solids where ions are fixed.
3) Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.
