Answer:
35. boiling point 100 Celsius
36. seven
sorry i dont know 37 AND 38. :(
Explanation:
To Find :
The STP moles of 67.2 L CO.
Solution :
We know, molar volume at STP is used to converted into moles by :
1 moles = 22.4 L STP
So, number of moles in 67.2 L CO is :
Therefore, number of STP moles are 3.
Hence, this is the required solution.
Answer:
The yield percent is 77.68%
Explanation:
1 mole of yields 2 moles of Fe.
So, 11.2 moles of Iron(III) oxide must yield 22.4 moles of Fe theoretically. This is according to the balanced equation.
Theoretical Yield = 22.4 moles of Fe
Experimental Yield = 17.4 moles of Fe
Therefore, the yield percent is 77.68%
