Choose the mixture that can act as a rockets propellant.
Correct answer: A. Liquid hydrogen + liquid oxygen
- A. Liquid hydrogen + liquid oxygen
- B. Liquid oxygen + liquid nitrogen
- C. Both a and b
- D. None of these
Explanation
A rocket propellant requires a fuel and an oxidizer that react to produce a large amount of hot gas for thrust. The combination of liquid hydrogen (the fuel) and liquid oxygen (the oxidizer) is a very high-energy and efficient propellant combination.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
