Liquid oxygen (LOX) is commonly used as a liquid oxidizer in rocket engines due to its high oxidizing potential and high density. Hydrogen peroxide is another liquid oxidizer used in some rocket engines and propulsion systems. Nitric acid is also used as a liquid oxidizer in certain applications.

Is liquid nitrogen an oxidizer?
dry ice −56.4 °C and liquid nitrogen is −196 °C
What are the 2 purposes of liquid oxygen?
Liquid oxygen is used primarily as an oxidizer in rocket propulsion systems to support combustion in engines. It is also used in medical applications to treat patients with respiratory problems or in hyperbaric chambers for therapeutic purposes.
Why is helium for Pressurizing Liquid-Fuel Rockets?
Helium is used to pressurize liquid-fuel rockets because it is inert, lightweight, and non-corrosive, ensuring it does not react with the rocket's fuel or oxidizer. It helps maintain a steady flow of fuel and oxidizer to the engines by keeping the propellant tanks pressurized. Additionally, helium's low boiling point allows it to remain in a gaseous state at low temperatures, which is crucial for spacecraft operating in the vacuum of space.
Is nitrox an oxidizer?
Yes, nitrox is an oxidizer. It contains a higher percentage of oxygen than normal air, which can increase the risk of oxygen toxicity if not used properly. Nitrox is commonly used in scuba diving to extend bottom time and reduce the risk of decompression sickness.
What is a container used to hold gas or liquid?
Liquid
What type of fuel is used in model rocketry?
There are two main types of fuel: solid fuel and liquid fuel. Rocket fuel most use both a fuel and an oxidizer. The solid fuel in most modern rockets uses aluminum powder as fuel, ammonium perchlorate as an oxidizer, and iron oxide as a catalyst. Liquid fuel uses liquid hydrogen as fuel and liquid oxygen as an oxidizer.
What are the constituents of rocket fuel?
Liquid hydrogen and liquid oxygen oxidizer.
What is usually used as an oxidizer in a rocket engine?
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.
What were the fuel oxidizer combinations used on each of the stages of the Redstone missile?
The Redstone rocket was fueled by a mixture of 25% H20 and 75% ethanol, and used liquid oxygen as the oxidizer. Redstone carried 19,000 lbs of fuel and 25,000 of oxidizer. Steam to drive the fuel and oxidizer pumps was produced by the decomposition of hydrogen peroxide (790 lbs of this were carried by Redstone).
What were the fuel oxidizer combinations used on each of the stages of the Atlas missile?
The Atlas missile used RP-1 (kerosene) for its fuel and LOX (liquid oxygen) as the oxidizer. Early versions used a stage and a half design where the sustainer engine would keep firing after the main engines cut off and were jettisoned. For the upper stages, propellant depended on which upper stage it used. The RM-81 Agena upper stage, used the hypergolic propellants UDMH (unsymmetric dimethylhydrazine) as the fuel and IRFNA (inhibited red fuming nitric acid) as the oxidizer. In the case that Atlas used the Centaur upper stage, Centaur used LH2 (liquid hydrogen) as the fuel and LOX (liquid oxygen) as the oxidizer.
What were the fuel oxidizer combinations used on each of the stages of the Minuteman missile?
The first three stages of the Minuteman II and III missiles used acrylic acid and aluminum powder for fuel, and ammonium perchlorate as the oxidizer. The binder, composed of polybutadiene, held the solid fuel/oxidizer mixture together. The fourth stage, called the payload bus, was equipped with a restartable liquid-fueled engine and used the hypergolic propellants monomethyl hydrazine (fuel) and nitrogen tetroxide (oxidizer).
What kinds of fuel do liquid fuel rockets use?
Liquid fuel rockets typically use liquid hydrogen and liquid oxygen as propellants. The hydrogen acts as the fuel, while the oxygen acts as the oxidizer. Other common combinations include RP-1 (a refined form of kerosene) and liquid oxygen, or hypergolic fuels like hydrazine and nitrogen tetroxide.
Why has liquid Fluorine never been used as an oxidizer on a launch?
Liquid fluorine is highly reactive, volatile, and dangerous to handle, making it challenging to use as an oxidizer in rocket propulsion systems. Its extreme reactivity with virtually all materials, including metals, poses significant safety risks and technical challenges that outweigh its benefits as an oxidizer. Additionally, alternative oxidizers like liquid oxygen are more widely used due to their proven reliability, storability, and compatibility with conventional materials.
How does the liquid fuel rocket work?
by burning liquid fuel with a liquid oxidizer in a combustion chamber connected to the exhaust nozzle. this generates thrust.
Is liquid nitrogen an oxidizer?
dry ice −56.4 °C and liquid nitrogen is −196 °C
What are the 2 purposes of liquid oxygen?
Liquid oxygen is used primarily as an oxidizer in rocket propulsion systems to support combustion in engines. It is also used in medical applications to treat patients with respiratory problems or in hyperbaric chambers for therapeutic purposes.
Which gas is used in rockets?
The primary performance advantage of liquid propellants is due to the oxidizer. Several practical liquid oxidizers (liquid oxygen, nitrogen tetroxide, and hydrogen peroxide) are available which have better specific impulse than the ammonium perchlorate used in most solid rockets, when paired with comparable fuels.
