Calculate the volume of carbon dioxide and water vapour produced and the volume of oxygen remaining, when 20.0 dm3 of propane re
acts with 120.0 dm3 of oxygen. All gas volumes are measured at the same temperature and pressure.
1 answer:
Answer:
80cm3 of water, and 60cm3 carbon IV oxide is formed while 20cm3 of oxygen is left unreacted.
Explanation:
From Gay-Lussac's law, there are five volumes of oxygen, 1 volume if propane, 4 volumes of water and three volumes of CO2. Applying this shows the reacting volumes as we have in the image attached, hence the volumes left after reaction.

Answer: 50.806 cm is the correct answer.
Explanation: First divide 6104.5 cm^2 by 22.3 cm.
*Note: When dividing units, subtract the exponents, and when multiplying units simply add the exponents.
Then continue by subtracting 324.55 cm - 273.74 cm.
This should give you an answer of 50.806 cm.
