How many moles of CO2 are produced when 35.0 mol C2H2 react completely?

Chemistry
1 answer:
GarryVolchara [31]3 years ago
4 0
1) Chemical reaction:


2C2H2 + 5O2 --->   4CO2 + 2H2O


2) Molar ratios


2 mol C2H2 : 5 mol O2 : 4 mol CO2 : 2 mol H2O



3) proportion with 35.0 mol C2H2


2 mol C2H2 / 4 mol CO2 = 35.0 mol C2H2 / x


=> x = 35.0 mol C2H2 * 4 mol CO2 / 2 mol C2H2 = 70.0 mol CO2.


Answer: 70.0 mol CO2
