What converts nitrogen into a form plants can use?
What converts nitrogen into a form plants can use?
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.
What do nitrogen fixing bacteria convert nitrogen into?
Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle.
How is nitrogen a significant gas Class 6?
(6) All the living things need nitrogen compounds for their growth. The plants use nitrogen gas of the air to make proteins. (7) These proteins are used by the plants for their own growth as well as for the growth of human beings and other animals.

Air is mostly gas It’s a mixture of different gases. The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
What are the most common uses of nitrogen?
Nitrogen is important to the chemical industry. It is used to make fertilisers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process.
Is dry ice the same as liquid nitrogen?
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.
What happens if you pour liquid nitrogen on dry ice?
Well, the first thing that happened is that the dry ice sank to the bottom. Steve: It turns out that dry ice is only 110 degrees below zero, but the nitrogen is 321 degrees below zero. So, to answer the question, “What happens when you mix dry ice and liquid nitrogen?” You get colder dry ice and less liquid nitrogen!
What happens if you touch dry ice?
The Effect of Dry Ice Like a very hot object, like a stovetop, dry ice has the same effect on skin and can cause a burn. If you touch dry ice momentarily without protective gear, it can cause redness to the affected skin. If you hold dry ice in your hand for a longer time, you can get frostbite.

Dry ice is safe to use in cocktails, it will not alter the flavor in any way. The ice will sink to the bottom of your glass, but take extra precaution not to ingest it or touch it in any way. You’ll need a hammer, screwdriver, and goggles to chisel your block of dry ice into ‘cubes’.
Is dry ice harmful?
Dry ice can be a very serious hazard in a small space that isn’t well-ventilated. As dry ice melts, it turns into carbon dioxide gas. In a small space, this gas can build up. If enough carbon dioxide gas is present, a person can become unconscious, and in some cases, die.
