Question
I understand how to do number 3a and b, I do not know how to do number 4.
3. Balance the following chemical reactions. a. C4Hio(butane)+02(oxygen gas)CO2(carbon dioxide)+H0(water) b. HIO3(lodic acid)+Fel2(Iron II idodide)+HCI(hydrochloric acid) Feci3(Iron chloride)+ICI(Iodine monochrodie)-H2O(water) For each of the reactions in problem 3, determine what percentage (by weight) of each compound must be provided as an input to the reaction and also provide the percentage (by weight) of each compound produced by the reaction. 4.Explanation / Answer
Ans 3 and 4
Part a
Balanced equation:
2 C4H10 + 13 O2 = 8 CO2 + 10 H2O
C4H10 + 6.5 O2 = 4 CO2 + 5 H2O
Basis 100 % of C4H10 consumed
As an input
C4H10 = 100%
O2 = 650%
Compound produced
CO2 = 400%
H2O = 500%
Part b
Balanced equation:
5 HIO3 + 4 FeI2 + 25 HCl = 4 FeCl3 + 13 ICl + 15 H2O
1.25 HIO3 + FeI2 + 6.25 HCl = FeCl3 + 3.25 ICl + 3.75 H2O
Basis 100 % of FeI2 consumed
As an input
FeI2 = 100%
HIO3 = 125%
HCl = 625%
Compound produced
FeCl3 = 100%
ICl = 325%
H2O = 375%
