Is boiling nitrogen in a laboratory a physical or chemical change?
Compression of nitrogen or any gas does not alter the chemical property...only changes involve in physical properties... On compression the gas molecules are come into more close..so it is pressurized..not change its chemical property...and whenever chances is come it s expand ..
Where did the nitrogen come from in earths atmophere?
Nitrogen in Earth's atmosphere is believed to have come from volcanic outgassing billions of years ago, as well as from the breakdown of ammonia in the early atmosphere through photochemical reactions. This nitrogen has been recycled through various natural processes, such as plant respiration and decomposition, contributing to the stable composition of nitrogen in the atmosphere.
Where does the hydrogen in a glucose molecule come from?
The hydrogen in a glucose molecule primarily comes from water molecules during the process of photosynthesis in plants. Plants absorb water from the soil and use energy from sunlight to break down the water molecules, releasing oxygen as a byproduct and incorporating the hydrogen into glucose molecules.
Where do the nitrogen oxide and sulphar dioxide in acid rain come from syk d?
Sulfur dioxide is created by the combustion of sulfur, sulfurous fuels (bunker oils, coal), the smelting of sulfide containing ores (pyrites) and hydrogen sulfide (usually as a waste/safety process). Sulfer can also be emitted from diesel engines as a sulfate solid. Nitrogen oxides (NOx) result from any combustion process where air and fuel are burned at the correct temperatures, the use of nitic acid in plan processes, fertilizer manufacturng and from lightning heating the air. As an aside the sulfur in acid precipitation is in the form of H2SO3. In the same way the NOx compounds form assorted nitrogen acids.
Compound forms hydrogen bonds?
Hydrogen bonds are formed between compounds containing a hydrogen atom covalently bonded to a very electronegative element. The only elements that are electronegative enough are fluorine, oxygen and nitrogen. The extreme difference in electronegativity causes the covalent bond between the atoms to polarize by attracting the centre of electron density towards the Hydrogen atom. This creates positive and negative ends of the compound. When the positive end of the compound (the Hydrogen atom) comes into contact with the negative end (the other element) of another compound (please note that the other compound must be the same compound or be capable of forming hydrogen bonds) it will form a temporary bond due to the differences in polarity (sign). This temporary bond is a hydrogen bond. Examples for compounds capable of forming hydrogen bonds are water (H2O), hydrogenflouride (HF) and the base pairs found in DNA.
Why is it necessary to burn the natural gas in the primary reformer Haber process?
the Haber process is endothermic. Energy to make the reaction take place must come from something.
Where does chemical fertilizer come from?
Chemical fertilizers are usually synthesized using minerals such as nitrogen, phosphorus, and potassium. These minerals are processed into various forms, such as ammonium nitrate, superphosphate, and potassium sulfate, which are then mixed and packaged as chemical fertilizers for agricultural use.
What does nylon come from?
Nylon can be composed of several different chemicals, but the most common elements are carbon, hydrogen, nitrogen and oxygen.
If you added a proton to hydrogen what do you now have?
This is a fusion process, the nuclear reaction that powers our Sun. Hydrogen and hydrogen isotopes come together to make helium
How does nitrogen absorb infrared radiation?
Nitrogen absorbs infrared radiation by vibrating and rotating its molecules when they come into contact with the radiation. This vibration and rotation process allows nitrogen to absorb and trap the infrared energy, which can lead to warming of the atmosphere.
Where do the hydrogen atoms in glucose come from?
The hydrogen atoms in glucose come from water molecules during photosynthesis. During this process, plants take in carbon dioxide and water, and through a series of reactions, convert them into glucose and oxygen. The hydrogen atoms from water molecules are incorporated into the glucose molecule.
Where does nitrogen from?
nitrogen come from the ground when it gets in the roots
Why gen come after hydrogen oxygen nitrogen?
-gen is Greek for "make" Hydrogen means "water maker" as water forms when it is burned. Oxygen essentially means "acid maker" acid as it was once falsely believed that all acids contained oxygen. Nitrogen essentially means "saltpeter maker" as nitrogen is a component of saltpeter, a.k.a potassium nitrate.
Where does hydrogen cyanide come from?
Hydrogen cyanide can be produced naturally in some plants like cassava, and it can also be formed through industrial processes such as the combustion of nitrogen-containing substances like plastics, synthetic textiles, and fossil fuels. Additionally, hydrogen cyanide is present in cigarette smoke and can be used in chemical manufacturing.
Can nitrogen rust?
No: Rusting occurs by the combination of ferrous metals with oxygen from air or water, and nitrogen can not form the same compounds as oxygen does.
What are five elements in living things?
The five elements found in living things are carbon, hydrogen, nitrogen, oxygen, and phosphorus. These elements are essential building blocks for biological molecules such as carbohydrates, proteins, nucleic acids, and lipids that make up living organisms.
What does the energy of a star come from?
Nuclear fusion, or the heating-up and smashing together of hydrogen nuclei, is the process via which stars produce energy.
