Post-Module Assessment typo?? - Balancing Chemical Reactions

Postby Jessica Dharmawan 1G » Fri Oct 05, 2018 9:10 am

On question #17, it asks us to balance the equation .
I believe the correct answer is C) , but the survey says it is wrong, maybe it's a typo?

There is no typo. The correct answer is D) . Answer choice D is the best answer choice for the balanced equation as the ratio of moles (the stoichiometric coefficients) are presented in the lowest terms.

The correct balanced equation would be CH4+2O2>CO2+2H2O not 2CH4+4O2>2CO2+4H2O. The coefficients of the equation can be further simplified by dividing by 2 therefore the balanced equation has a ratio of 1:2:1:2.

Prof. Lavelle mentioned that balancing rxns is just like solving math equations so if you left your answer as is it would be like saying 2x=2 when you really should simplify to x=1 if that makes sense.
