The answer is 60 minutes to complete 50% of reaction.
Answer: The distillation flask being heated in a heating mantle. The vapors condense and drip from the condenser into the flask. As the distillate begins to drop from the condenser, the temperature observed on the thermometer should be changing steadily.
Explanation:
answer above
Answer:water is a universal solvent because It is capable of dissolving more substances than any other liquid
Explanation:
Answer:
V = 0.2714 mL
Explanation:
Henry's Law:
∴ Kh CO2 = 0.034 M/atm ....The Henry's constant
∴ Partial pressure: P CO2 = 3.7 atm
⇒ <em>C</em> CO2 = P CO2 / Kh
⇒ <em>C</em> CO2 = 3.7 atm / 0.034 M/atm = 108.823 M (mol/L)
∴ molar mass CO2 = 44.01 g/mol
⇒ mol CO2 = (1.3 E3 mg)(g/1000 mg)(mol/44.01 g) = 0.03 mol CO2
volumen solution:
⇒ V sln = (0.03 mol)(L/108.823 mol) = 2.714 E-4 L
⇒ V sln = 0.2714 mL
