Which of the following fertilizers has the maximum percentage of nitrogen in solid state?
Correct answer: A. Ammonia
- A. Ammonia
- B. Urea
- C. Di ammonium hydrogen phosphate
- D. Ammonium nitrate
Explanation
Anhydrous ammonia, NH 3, is typically among the least expensive sources of nitrogen and contains 82 percent nitrogen by weight, the highest of all available sources. We have to find percentage of nitrogen in given compounds: For ammonia, NH3 →N = 14 H=1 = (1 x 14)(3 × 1) =14+3 - 17 = 14/17 x 100 = 0.8235 x 100 = 82.35%

About Reactions of Group IV Elements
Group IV, or Group 14, chemistry covers the trends from carbon and silicon to tin and lead, including their reactions with oxygen, halogens, water, acids and alkalis. It also examines the structures and properties of their oxides and chlorides, oxidation states, and the inert pair effect, rather than treating all members as equally metallic.
