Given the equation: C2H6 (g) + O2 (g) → CO2 (g) + H2O (g) (not balanced) Determine the number of liters of O2 consumed at STP when 60.0 grams of C2H6 is burned.
Write a balanced equation for the chemical reaction Acetylene gas (C2H2) burns in a welding torch with oxygen to form carbon dioxide gas and water vapor.C2H2(g) + O2(g) ==> CO2(g) + H2O(g) It isn't balanced. I will leave that for you.How do I balance it?trial and error. C2H2 + O2 ==> CO2 + H2O. I see 2 C on the left and only 1 on the right so I place a coefficient of 2 for CO2 on the right. And...
