Yes. Yes.
No. Burning is generally something that occurs at an elevated temperature. Liquid nitrogen is a cryogenic material; it is terribly cold. It is possible for liquid nitrogen to turn some metals as brittle as glass or a candy cane, making them easy to break. But it cannot burn metal, thermically nor chemically.
Liquid nitrogen is not poisonous, however, it can be dangerous if it comes into contact with skin or if it is inhaled because of its extremely low temperatures. It can cause severe burns or frostbite upon contact with skin and can displace oxygen in the air if inhaled in high concentrations.
No, nitrogen does not burn in oxygen. Nitrogen is inert and does not react with oxygen under normal conditions.
No, liquid nitrogen is not sticky—it is a colorless, odorless, non-sticky, and non-toxic liquid. Liquid nitrogen is extremely cold at -320°F (-196°C) and can cause severe frostbite if it comes into contact with skin due to its rapid cooling effect.
Liquid nitrogen is a compound, specifically dinitrogen (N2), since it consists of nitrogen molecules made up of two nitrogen atoms bonded together. It is the liquid form of the nitrogen gas found in our atmosphere.
Nitrogen must be cooled to a very low temperature to become liquid nitrogen. At room temperature, liquid nitrogen will change from the liquid phase to the gas phase. Therefore, if the skin is treated with liquid nitrogen, the liquid nitrogen will almost instantly become a gas and evaporate away from the skin. It is impossible to "leave" it on the skin, as this reaction is almost instantaneous and no liquid nitrogen is left behind.
Liquid nitrogen, which is very cold, is often used to freeze warts and skin cancers quickly so that they can be safely removed from the skin. This process is sometimes loosely called "burning off" the skin blemishes so treated, but it is not burning in the chemical sense. Any other cold liquid that does not adversely react with skin could be used as well, but liquid nitrogen is usually cheaper than any other available liquid. The chemical properties of nitrogen, other than non-reactivity, have nothing to do with this use of the element.
It is Acid
Liquid nitrogen.
No. Nitrogen does not irritate skin. But liquid nitrogen is extremely cold, and it can damage and kill skin (and other) tissue. It is a bad idea to allow your skin to come into contact with liquid nitrogen. Note: Some warts are "frozen" in an effort to remove them. In a clinical setting, liquid nitrogen is sometimes used to super-cool an instrument so the wart can be frozen. But this is a medical procedure and is done by professionals. Liquid nitrogen is not something that should be looked upon as a "toy" or "recreational plaything" by anyone.

an acid
Acid
Yes, gasoline can burn the skin because it is a flammable liquid that can cause skin irritation and burns upon contact.
yes.it destroys the skin.
liquid nitrogen
Nitrogen is an inert gas and does not typically have direct effects on the skin. However, exposure to liquid nitrogen can cause frostbite and skin damage due to extreme cold temperatures. Nitrogen gas itself is non-toxic and generally safe for skin contact.
