Why does liquid nitrogen exposed to air is a physical change?
Evaporation is a physical change; nitrogen remain nitrogen.
Can liquid nitrogen be used as a fertilizer for agriculture?
No. Firstly liquid nitrogen has a boiling point of 77K. That's -196degrees Celsius, which will freeze all water in contact with it. Not only will the roots not be able to take up water from the soil, water within the plant cells will also freeze, damaging the roots. Secondly, liquid nitrogen will vaporize rapidly when exposed to the environment, which is at room temperature. This means that when liquid nitrogen is poured into the soil, it is not different from the plant absorbing nitrogen in the form of gaseous nitrogen. Thirdly, nitrogen uptake is best facilitated in the aqueous form, ie. dissolved in water in the form of nitrate or ammonium ions. Liquid nitrogen/gaseous nitrogen do not dissolve very well in water.
What is a chemical or physical process in which rocks exposed to the weather are worn down by water wind or ice?
Smaller particles of rock are produced from larger particles.
Why are nitrogen oxides produced when fuels burn in vehicles?
Oxygen and Nitrogen from the air react at engine temperature. This makes nitrogen monoxide which, when it is released into the atmosphere reacts with more oxygen in the air to form nitrogen dioxide :)
How long does it take for aluminum foil to biodegrade?
Aluminum foil does not biodegrade. Biodegradation only happens when microorganisms (microbes, fungi etc.) use a material as food. Aluminum foil can chemically degrade if exposed to acids or alkalis in soil or groundwater. It can be converted to aluminum oxide in a fire. It can be shredded into very small particles by abrasion, the smaller particles are more apt to be oxidized or dissolved. If not exposed to this physical degradation aluminum will last for thousands of years
Why does liquid nitrogen exposed to air is a physical change?
Evaporation is a physical change; nitrogen remain nitrogen.
If liquid nitrogen freezes everything why is itself a liquid?
liquid nitrogen will not freeze everything. Hydrogen and helium will remain a gas when exposed to liquid nitrogen.
Enzyme that adds nucleotides to exposed nitrogen bases?
The enzyme that adds nuclleotides to exposed nitrogen bases is DNA polymerase. This is how DNA can be replicated or repeated in the cell cycle.
Why don't Fe rust when exposed to N?
Rust - by definition - is oxidation. It requires oxygen. If it's exposed to nitrogen, it's not oxidizing.
What enzyme that adds nucleotides to exposed nitrogen bases?
DNA and RNA polymerase
Are smaller particles weathered more rapidly than larger particles?
Yes, because smaller particles are more exposed to air (large surface area).
What was Ernest Rutherford's real job?
rutherford's first researches, in new zeland, were concerned with the magnetic properies of iron exposed to high frequencys discovered new noble gas isotope of radon which is known as thoron
Can unused wind blown Gunite particles be dangerous to an indivuals health.?
Gunite particles can be dangerous to health. For workers routinely exposed to the particles, OSHA says that silicosis can develop.
A type of pollution that forms when nitrogen and carbon compounds are exposed to sunlight is called?
photochemical smog
What happens to air particles exposed to a laser beam?
They become partially energised, leeching off the stimulated light. It creates hot particles.
What is the formula for the compound nitrogen monoxide?
The formula is is 'NO'. The 'N' comes from one Nitrogen atom, and the O from one Oxygen(Monoxide) atom. If NO is exposed to oxygen, it will take on an extra Oxygen atom and become NO2. (Nitrogen Dioxide)
Once a DNA molecule unzips exposed nitrogen base pairs have a strong attraction to each other?
true
