Which of the following could act as apropellant for rockets?

Options

  1. ALiquid oxygen + liquid argon
  2. BLiquid hydrogen + liquid oxygen
  3. CLiquid nitrogen + liquid oxygen
  4. DLiquid hydrogen + liquid nitrogen

Correct answer

B. Liquid hydrogen + liquid oxygen

Step-by-step solution

Liquid hydrogen and liquid oxygen are used as excellent fuel for rockets. H ₂(l) has low mass and high enthalpy of combustion whereas oxygen is a strong supporter of combustion
