Solution: Balance the following combustion reaction in order to answer the following questions. Use lowest whole-number coefficients C2H4 + O2 → CO2 + H2O Tip: If you need to clear your work and reset the equation, click the button that looks like two red arrows. You are given 9.5 moles of O2 to react with 145 g C2H4. Upon completion of the reaction, will there be any remaining C2H4?a. Yes, there will still be C2H4 remaining. b. No, all C2H4 will be used up in the reaction. 

Problem

Balance the following combustion reaction in order to answer the following questions. Use lowest whole-number coefficients 

C2H+ O2 → CO2 + H2

Tip: If you need to clear your work and reset the equation, click the button that looks like two red arrows. You are given 9.5 moles of O2 to react with 145 g C2H4. Upon completion of the reaction, will there be any remaining C2H4?

a. Yes, there will still be C2H4 remaining. 

b. No, all C2H4 will be used up in the reaction.
