Please balance this equation:
FeS2 + O2 ----> Fe2O3 + SO2
Is this a combustion equation?© BrainMass Inc. brainmass.com October 24, 2018, 10:40 pm ad1c9bdddf
Hello, and thank you for posting your question to BrainMass.
Let's write the equation with arbitrary coefficients:
a FeS2 +b O2 ---> c Fe2O3 + d SO2
Now we equate the number of atoms of each specie on both sides:
Fe: a = ...
This response provides assistance in balancing an equation and explains whether or not the reaction is combustion.
Formula of Compound given combustion reaction, dumas method
A compound contains only C, H, and N. A chemist analyzes it by doing the following experiments.
(a) Complete combustion of 35.0 mg of the compound produced 33.5 mg CO2 and 41.1 mg H2O.
(b) A 65.2 mg sample of the compound was analyzed for nitrogen by the Dumas method, giving 35.6 mL of dry N2 at 740. torr and 25°C.
(c) The effusion rate of the compound as a gas was measured and found to be 24.6 mL/min. The effusion rate of argon gas, under identical conditions, is 26.4 mL/min.
