How to write a complete combustion equation?
hydrocarbon + oxygen → carbon dioxide + water Here are the equations for the complete combustion of propane, used in bottled gas: propane + oxygen → carbon dioxide + water C3H8 + 5O2 → 3CO2 + 4H2O
What is the balanced equation for acetylene?
What is the balanced equation for the complete combustion of acetylene? The combustion of acetylene gas is represented by this equation: 2C2H2 (g) + 5O2 (g) – – > 4CO2 (g) + 2H2O (g) How many liters of CO 2 are produced when 52.0 g C2H 2 burns in oxygen? Oxyacetylene is the hottest burning common fuel gas. If not enough oxygen is present for complete combustion, incomplete combustion occurs.
How to balance the combustion equation?
– C 3 H 8 + O 2 –> H 2 O + 3 CO 2 – The coefficient 3 in front of carbon on the right side indicates 3 carbon atoms just as the subscript 3 on the left side indicates 3 carbon atoms. – In a chemical equation, you can change coefficients, but you must never alter the subscripts.
What is the reaction of acetylene with KMnO4?
Ans: Acetylene reacts with Cold KMnO4 to form formic acid and on reaction with hot KMnO4 it forms Oxalic acid. What happens when ethylene is treated with an alkaline solution of potassium permanganate?
