Question

Liquid $ - - - - $ is used along with liquid $ - - - - $ to make rocket fuel.

Answer 1

Hint :Rocket engines and boosters carry both fuel and an oxidizer. For solid fuel, the components are aluminium and ammonium perchlorate. For solid fuel, the most common element required by rockets is aluminium. These fuels help rockets to leave the ground.

Complete Step By Step Answer:
The components are liquid hydrogen and liquid oxygen for rocket liquid fuel. When it combines the fuel just releases water, which allows the rocket to start and leave the ground. There are actually two kinds of fuels used in rockets. One is solid fuel and the other is liquid fuel. With solid fuel, there must be these two that are fuels and an oxidizer to make a solid fuel rocket leave. This oxidizer is required by the rocket because it makes fuel burn. We are aware that space has no atmosphere, hence rockets have to carry both their own fuel and their own oxidizer.
 Most common fuel in solid fuel rockets is aluminium. In order to make aluminium burn these solid fuel rockets use ammonium perchlorate. In order to make the aluminium perchlorate as the oxidizer, or to make the aluminium burn. In order to make the aluminium and the ammonium work together, these are held together with the help of binder. When mixed all together, the fuel has a slightly rubbery consistency. This rubbery substance is then packaged into a casing. As the fuel burns, the heat and energy causes the inside of the rocket to heat up.

Note :
The liquid hydrogen is fuel and the liquid is oxidizer. Remember, the oxidizer helps the fuel burn. The second most long lasting fuel are the rocket fuel which can be beaten by only nuclear fuel .These are used in production of orbitals rockets.
