To determine the grams of ammonia (NH₃) consumed in its reaction with nitric oxide (NO), we first need the balanced chemical equation for the reaction: 4 NH₃ + 6 NO → 5 N₂ + 6 H₂O. From the equation, 4 moles of NH₃ react with 6 moles of NO.
Calculating the moles of NO in 40.0 grams (molar mass of NO = 30.01 g/mol), we find it to be approximately 1.33 moles. Using the stoichiometric ratio (4 moles NH₃ for every 6 moles NO), we calculate that about 0.89 moles of NH₃ are needed. Converting this to grams (molar mass of NH₃ = 17.03 g/mol) gives approximately 15.2 grams of NH₃ consumed.
What role does nitrogen play in a nutrient cycle?
The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This transformation can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.
What happens when you expose nitrogen gas to alpha particles?
When nitrogen gas is exposed to alpha particles, a nuclear reaction can occur if the energy of the alpha particles is sufficiently high. This can lead to the transmutation of nitrogen into oxygen, as the alpha particles may collide with nitrogen nuclei and cause them to emit protons or neutrons. Specifically, one reaction that can occur is the conversion of nitrogen-14 to oxygen-17 through the emission of a proton. However, this process requires high-energy alpha particles, such as those produced in certain types of nuclear reactions or radioactive decay.
Where did nitrogen get its name?
The name "nitrogen" comes from two Latin words meaning "nitre-forming", nitre being potassium nitrate (saltpetre). Daniel Rutherford, the Scottish doctor who discovered nitrogen in 1772, dubbed it "noxious air" or "fixed air".
The chemist Lavoisier called it azote, from the Greek for "lifeless", because nitrogen seemed inert. This name can still be seen in some modern names of compounds, such as hydrazine. Also, it can be called "burnt air" meaning "air without oxygen".
It came from the term nitre, an alternative name for saltpeter (potassium nitrate).
nitrogen=nitre+gen=nitre maker
Where does nitrogen in the atmosphere come from?
Nitrogen in the atmosphere primarily comes from volcanic eruptions and the decay of organic matter, but the largest source is the Earth's crust, where nitrogen is released through geological processes. Additionally, nitrogen is continuously cycled through biological processes, such as nitrogen fixation by certain bacteria, which convert atmospheric nitrogen into forms usable by living organisms. Ultimately, about 78% of the Earth's atmosphere is composed of nitrogen gas (N₂), making it the most abundant gas in the atmosphere.
Can nitrogen be used in electricity?
Nitrogen itself is not a direct source of electricity, as it is an inert gas and does not conduct electricity. However, nitrogen can be used in various processes related to electricity generation, such as in gas turbines where it can serve as a working fluid, or in the production of ammonia through the Haber process, which can be utilized in energy storage systems. Additionally, nitrogen gas is often used in cooling systems for power plants and electrical equipment.
Where to buy nitrogen gas middletown NJ?
You can purchase nitrogen gas in Middletown, NJ, from local industrial gas suppliers such as Airgas or Praxair. Additionally, welding supply stores often carry nitrogen in various quantities. It's advisable to call ahead to check availability and ensure they provide the specific type of nitrogen gas you need. Lastly, consider online suppliers that may deliver to your area.
Is it safe to use liquid nitrogen to make ice cream?
It can be either safe or unsafe to make ice cream this way, depending on who is handling the nitrogen and how they do it.
Children should never be allowed to make ice cream this way, an adult must always be the one handling liquid nitrogen when it is used for any purpose!
How nitrogen oxides are produced in petrol engine?
There are N in fuel. In very high heat N is oxidized into its maximum
What force holds nitrogen crystals together?
The dispersion force is responsible for holding nitrogen crystals together
What do nitrogen fixing bacteria convert in the nitrogen cycle?
Nitrogen fixing bacteria are anaerobic bacteria present in the soil or in some plant roots that change nitrogen gas from the atmosphere into solid nitrogen compounds (e.g. ammonium salts) that plants can use in the soil.
Nitrogen fixing bacteria that are symbiotic with plants use sugars supplied by the plant they live in to provide the metabolic energy to carry out this process.
How big is a 2 liter liquid nitrogen container?
About twice the size of a 2 liter soda bottle. Liquid nitrogen is extremely cold- the container must be vacuum insulated, or the liquid nitrogen quickly turn to gas.
Is nitrogen produced during the preparation of oxygen from hydrogen peroxide?
No. The only products are oxygen and water.
