What is the composition of nitrolim?

What is the composition of nitrolim?

Explanation: When nitrogen is passed over calcium carbide at a suitable high temperature, we get a mixture called nitrolim which is a nitrogenous fertilizer, which is a mixture of calcium cyanamide and carbon.

What is nitrolim and what is its use?

Nitrolim: It is an inorganic compound which is also known as Calcium cyanamide with the formula CaCN2 . It is the calcium salt of the cyanamide (CN−) ion. This chemical is used as fertilizer in the agricultural industry.

How will you obtain nitrolim?

  1. Class 12.
  2. >>Chemistry.
  3. >>The p-Block Elements.
  4. >>Dinitrogen.
  5. >>Nitrolim is obtained by heating calcium.

How is nitrolim prepared reaction?

Preparation of Nitrolium Calcium cyanamide is synthesised from calcium carbide. The carbide powder is heated at about 1000 °C in an electric furnace into which nitrogen is passed for several hours. The product is cooled to ambient temperatures and any unreacted carbide is leached out cautiously with water.

What is the composition of nitrogen A chemical fertilizers?

Composition: nitrogen (N) 27 % (ammonia N (N-NH4) – 13.5 %, nitrate N (N-NO3) – 13.5 %), magnesium (MgO) – 4.0 %, calcium – 6.0 %. Fertilizing effect: nitrogen is absorbed easily and efficiently.

What is Thomas slag?

Calcium silicophosphate (a mixture of Ca3(PO4)2 and CaSiO3) is called Thomas slag. Slag is easily fusible material and is lighter and forms upper layer.

Is Nitrolium a fertilizer?

Nitrolium is used as fertiliser.

What is Nitrolim phosgene?

mixture of calcium carbide and nitrogen.

What is nitrolim phosgene?

What is superphosphate of lime?

superphosphate or superphosphate of lime, Ca(H2PO4)2, is a compound produced by treating rock phosphate with sulfuric acid or phosphoric acid, or a mixture of the two. It is the principal carrier of phosphate, the form of phosphorus usable by plants, and is one of the world’s most important fertilizers.

Which of the following is the correct combination of nitrolim?

Nitrolim is a mixture of CaCNX2 and graphite (c) which is used as fertilizer. Option (b) is correct.

What is the highest nitrogen fertilizer?

Urea has the highest nitrogen content of all solid fertilizers at 46% N.

Which fertilizer have the highest percent composition of nitrogen?

The correct answer is Urea.

  • Urea. It is the most important nitrogenous fertilizer in the country because of its high N content (46%N).
  • DAP. It is Di-ammonium Phosphate.
  • Ammonium nitrate. It is hygroscopic and therefore readily attracts moisture from the air.

What is the formula of slag?

The slag can generally be expressed by the formula FeSNa2S(O). Both reactions 9.5 and 9.6 are heterogeneous and endothermic in nature.

Which is constituent of Thomas slag?

Tetra calcium phosphate
Tetra calcium phosphate, Ca4(PO4)2 O is known as Thomas slag. It is used as phosphorus fertilizer.

How is cyanamide made?

Cyanamide is produced by hydrolysis of calcium cyanamide, which in turn is prepared from calcium carbide via the Frank-Caro process. The conversion is conducted on slurries.

What is phosgene gas used for?

Phosgene is a major industrial chemical used to make plastics and pesticides. At room temperature (70°F), phosgene is a poisonous gas. With cooling and pressure, phosgene gas can be converted into a liquid so that it can be shipped and stored.

What is super phosphate fertilizer composition?

SSP – A multi nutrient fertilizer containing phosphorus (14.5 %), Sulphur (11%) and Calcium (21 %). SSP can apply as a basal fertilizer with other chemicals and organic fertilizers. It has tremendous impact on plant growth and also assisting in maintain soil health and protection against pest and diseases.

What chemicals are in superphosphate?


  • Fertilizer.
  • Nitrogen.
  • Calcium Phosphate.
  • Calcium Sulfate.
  • Phosphorus(.)
  • Phosphoric Acid.
  • Phosphate.
  • Ion.

What manure has the most nitrogen?

poultry manure
Generally, poultry manure is highest in nitrogen content, followed by hog, steer, sheep, dairy, and horse manure. Feedlot, steer manure requires fairly high rates to meet first-year nitrogen requirements because of its lower nitrogen percent and gradual nitrogen release characteristics.

Why is urea better than ammonium nitrate?

Studies show that urea has a positive impact on the metabolism of plants. Using urea yields faster growth rates and more production in less time. In the past 10 years, urea fertilizer has surpassed and nearly entirely replaced ammonium nitrate in fertilizer use.

What is slag content?

However, slags can contain metal sulfides and elemental metals. The major components of these slags include the oxides of calcium, magnesium, silicon, iron, and aluminium, with lesser amounts of manganese, phosphorus, and others depending on the specifics of the raw materials used.

What is the composition of the atmosphere?

Why is nitrogen the most abundant gas in the atmosphere?

While nitrogen is the most abundant gas in Earth’s atmosphere, it only makes up 0.005% of Earth’s crust in weight (David Darling). Nitrogen is incredibly stable and requires a lot of energy to change forms. Even though its volume in Earth’s crust is relatively small, nitrogen plays an important role in the nitrogen cycle.

What is the composition of the troposphere?

Because the troposphere is the lowest atmosphere layer, it contains 75 percent of the atmosphere’s mass. From largest to smallest, Earth’s atmosphere composition contains nitrogen, oxygen, argon, CO 2 and trace gases. Because water vapor is highly variable geographically, it’s excluded from this total. Table of Contents show

What are the two main gases of the atmosphere?

Nitrogen and Oxygen are the two main gases of the atmosphere. 99 percent part of it is made up of these two gases. Other gases like organ, carbon dioxide, hydrogen, nion, helium etc. form the remaining part of atmosphere.
