The typical charge for nitrogen is between $5 and $10 per tyre for a passenger car. Once your tyres are filled with nitrogen it's important that only nitrogen is used for top up purposes. Adding normal compressed air is likely to negate any benefits of the nitrogen.

Nitrogen and hydrogen combine at high temperature, in the presence of a catalyst, to produce ammonia. N2(g) + 3H2(g) = 2NH3(g) Assume 4 molecules of nitrogen and 9 molecules of hydrogen are present.

6 * 2/3 moles of ammonia must be produced. Therefore 4 moles of ammonia can be produced.

By BBC Reality Check's Anthony Reuben The Committee on Climate Change puts the cost of achieving net zero greenhouse gas emissions by 2050 at between 1% and 2% of GDP - the total output of the UK economy - a year. GDP is currently about £2tn a year, so, at the moment, that amount would be between £20bn and £40bn.

To get the elements needed to make anhydrous ammonia (chemical name NH₃) three things are required: natural gas, steam, and air. The hydrogen comes from two sources, natural gas (methane CH₄) and steam (H₂O). The nitrogen is pulled from the air. ... Anhydrous ammonia boils at -28º F and has an expansion rate of 30 to 1.

You need 1 mole of nitrogen and 3 moles of hydrogen to make 2 moles of ammonia. If we multiply these numbers by 2, we can also say you need 2 moles of nitrogen and 6 moles of hydrogen to make 4 moles of ammonia. (And you'd have 1 mole of nitrogen left over.) And that's the answer: you'd get 4 moles of ammonia.

The FDA said the liquid nitrogen is so cold it could be harmful to a person's health. Officials said eating liquid nitrogen could burn someone's throat because it is so cold. In some extreme cases, it could cause internal damage to organs. Doctors said people need to be careful when eating the sweet treat.

By way of example, if you have a fridge with a top freezer from the 1980s with a capacity of 19.0-21.4 cubic feet, it's likely to use around 2,000 kWH per year. If you pay $. 10 for electricity per kWh, that means the aging refrigerator is costing you about $. 55 per day, $16.67 per month, and $200 per year.

An energy-efficient large freezer with more than 25 cubic feet will use about 956 kilowatt-hours per year, according to EnergyStar.gov. That equates to about $10 a month. When you reduce the size of your freezer, your costs go down. Standard freezer sizes run between 19 cubic feet and 22 cubic feet.

Liquid nitrogen is the colorless, odorless, clear liquefied form of nitrogen with a density of 0.807 g/ml at its boiling point (−195.79 °C (−320 °F)) while dry ice is an opaque solid with a density of 97.5189 lb/ft3 at 78.5 °C (109.3 °F). Both liquid nitrogen and dry ice can maintain extremely low temperatures.
