Liquid hydrogen is a common fuel used in rocket engines.
Liquid oxygen (LOX) is commonly used as an oxidizer in rocket engines due to its high oxidizing power and high density, which allows for efficient combustion reactions in the engine.
A rocket has it's own supply of oxygen.
Oxygen is transported as a liquid in a rocket ship because liquid oxygen is more dense and takes up less space than gaseous oxygen, allowing for more efficient storage in the limited space of a rocket. Additionally, liquid oxygen is more stable and easier to control during the combustion process in the rocket engine.
You didn't provide a list for "Which of the following....", so we don't know what you're looking for. However, kerosene, hydrazine, liquid oxygen, and red fuming nitric acid are among some of the often-used liquid rocket fuels. Commercial organizations generally use things like liquid oxygen and kerosene, which are inexpensive and relatively safe fuels. NASA often prefers fuels with a slightly higher energy like hydrazine, even though hydrazine and RFNO are very expensive, difficult to work with, and VERY hazardous.
The fuel inside a rocket can vary depending on the type of rocket. Common rocket fuels include liquid hydrogen, liquid oxygen, kerosene, and solid propellants like ammonium perchlorate. These fuels are used to generate the energy needed to propel the rocket into space.
A liquid-fuel rocket or a liquid rocket is a rocket with an engine that uses propellants in liquid form.

One of the most advanced rocket engines is the Raptor engine developed by SpaceX. It is a full-flow staged combustion engine that uses liquid methane as fuel and liquid oxygen as oxidizer. The Raptor engine is designed to power the Starship spacecraft for missions to Mars and beyond.
Robert Goddard invented the first liquid-fueled rocket engine in 1926. The liquid fuel he used was a combination of gasoline and liquid oxygen. This innovation paved the way for modern rocket technology.
Two common elements found in rocket fuel are liquid oxygen (O2) and liquid hydrogen (H2). When these two elements are combined and ignited in the rocket engine, they react to produce a powerful thrust that propels the rocket into space.
The propulsion force of a rocket is the force generated by expelling exhaust gases at high speeds through the rocket's engine nozzle. This force propels the rocket in the opposite direction, following Newton's third law of motion (action and reaction). It enables the rocket to overcome gravity and atmospheric resistance to launch and travel through space.
There are solid rocket fuels, and there are liquid rocket fuels.
Yes, that's correct. Liquid fuel and an oxidizer are burned in the rocket engine's combustion chamber to create high-pressure exhaust gases that are expelled out of the nozzle at high speed, generating thrust that propels the rocket forward.
Rocket fuels are any of the substances or mixtures of substances that can burn rapidly with controlled combustion to produce large volumes of gas at high pressures and temperatures. Fuel for the space shuttle is almost entirely liquid O2 (liquid oxygen) and is pale blue.
Liquid oxygen (LOX) is commonly used as an oxidizer in rocket engines due to its high oxidizing power and high density, which allows for efficient combustion reactions in the engine.
