Ethanol is a product of fermentation.
Answer:
The boiling point is directly proportional to the surface area which is proportional to the molecular weight.
Explanation:
Answer is: concentration of hydronium ions is 8.13·10⁻⁴ M.<span>
c(HNO</span>₂) = 0.055 M.<span>
c(NaNO</span>₂) = 0.10 M.<span>
Ka(HNO</span>₂) = 4.5·10⁻⁴.<span>
This is buffer solution, so use Henderson–Hasselbalch equation:
pH = pKa + log(c(NaNO</span>₂) ÷ c(HNO₂)).<span>
pH = -log(4.5·10</span>⁻⁴) + log(0.055 M ÷ 0.10 M).<span>
pH = 3.35 - 0.26.
pH = 3.09.
</span>[H₃O⁺<span>] = 10</span>∧(-3.09).
[H₃O⁺] = 8.13·10⁻⁴ M.
<span>Condensation takes place when gas molecules lose heat and kinetic energy. The warmer molecules are the faster they move. Gas molecules move very quickly and have a lot of kinetic energy and heat energy. As the gas molecules lose heat they also lose kinetic energy. As the molecules slow down they move closer together to form liquids.</span>
