In the given reaction hydrogen reacts with oxygen to produce water. directly helping charity project in Vietnam building shcools in rural areas. Redox reactions always occur together; if one reactant in a chemical reaction is oxidized, then another reactant must be reduced. For C2H6 we have 2 moles / 2 = 1 For O2 we have 8 moles / 7 = 1.14 So in this case C2H6 would be limiting reactant and O2 would be in excess jackson state football walk on tryouts 2021, The combustion of Organic compounds usually takes the form: Organic compound + oxygen >!
