Which of the following statements is correct regarding the products of combustion, neutralization and electrolysis of water-related reactions?
- A. The products of combustion of hydrocarbon are CO2 and H2O; the products of neutralization of an acid by a base are salt and water; the products of electrolysis of brine are hydrogen at the cathode and chlorine at the anode; the only product obtained during the combustion of hydrogen is waterCorrect
- B. —
- C. —
- D. —
Explanation
The products of combustion of hydrocarbon are CO2 and H2O. The products of the neutralization of an acid by a base are salt and water. The products of the electrolysis of brine are hydrogen (at the cathode) and chlorine (at the anode). The only product obtained during the combustion of hydrogen is water: 2H2+O2->2H2O.
