Answer:
79.14%
Explanation:
Given the equation : 2Fe2O3 + 3C 4Fe + 3C02
The theoretical yield of CO2 ; is 102.6g
Actual yield = 81.2 gram
Percentage yield = (actual yield / theoretical yield) * 100%
Percentage yield = (81.2 / 102.6) * 100%
Percentage yield = 0.7914230 * 100%
Percentage yield = 79.14%
Hence, tbe percentage yield of CO2 is 79.14%
Carbon and Hydrogen are present in all organic compounds !
Answer:
The temperature would be 194, 8 K.
Explanation:
We use the formula:
PV=nRT --> T=PV/nR
T= 0,500 atm x 28, 6 L/ 0,895 mol x 0,082 l atm /K mol
<em>T= 194,8494345 K</em>
