Write a balanced equation for the combustion of gaseous ethylene (C2H4), an important natural plant hormone, in which it combines with gaseous oxygen to form gaseous carbon dioxide and gaseous water

Answer 1

C2H4 + O2 ---> CO2 + H2O
Balancing, it becomes
C2H4 + 3O2 ---> 2CO2 + 2H2O

Answer 2

this answer is only partially correct... the correct answer is

C2H4(g)+3O2(g)-->2CO2(g)+2H2O(g)

Answer 3

How many grams of carbon dioxide were formed
