Answers:
1.
The mole ratio of AlCl₃ to Cl₂ is 2 : 3. This means for production of every 2 moles of AlCl₃ 3 moles of Cl₂ is consumed. Hence, if 3 moles of AlCl₃ is produced then Cl₂ consumed is,
= 3 × 3 / 2
= 4.5 moles of Cl₂
2.
Mole ratio of C₃H₈ to CO₂ is 1 : 3.
Hence, 0.5 moles of C₃H₈ will produce 1.5 moles of CO₂.
Also,
At STP one mole of an ideal gas occupied 22.4 L of volume. Hence, 1.5 moles of CO₂ gas will occupy,
Volume = 1.5 mol × 22.4 L/mol
Volume = 33.6 L of CO₂
Answer:
I think the answer is 800J
Explanation:
As the kinetic energy goes down, the potential energy goes up
Answer:
Because the atmospheric pressure at higher altitudes is lower than at sea level.
Water, or any liquid for that matter, boils when its vapor pressure equals the external pressure above the liquid.
I would say A but I am not sure
