Ammonia in water acts as a caustic but weak base. Its high pH breaks down organic material, making urine the perfect substance for ancients to use in softening and tanning animal hides. ... Even though early Europeans knew about soap, many launderers preferred to use urine for its ammonia t...
Why does a strong acid and weak base result in a pH lower than 7, and does a weak acid and strong base result in a pH higher than 7? Why is the pH different below the thermocline in a body of water? What makes something acidic?
Bc3 controlled the hydrolysis of organic N to ammonia in reach, and Bc1 regulated the process of biological oxidation of NH3 to NO2 in reach. Four parameters were also identifiable in the P cycle, namely, Lat_orgp that determined the initial amount of organic P in lateral flow (Fig. S3u...
Classify each of these soluble solutes as either a strong electrolyte, a weak electrolyte, or a non-electrolyte a) Sulfuric acid- H2SO4 b) Potassium hydroxide- KOH c) Carbonic acid- H2CO3 d) Ammonia- NH3 e) Potassium chloride- KCl f) Butanol-...
Although there are plans for many new uses, such as powering vehicles, hydrogen has had industrial uses for a long time. At present, it's mainly used to make other chemicals, such as ammonia for nitrogen fertilizer. However, most of this hydrogen is produced globally using fossil fuels, whi...
How do you acidify a solution? a. Place 10 drops of the original test solution (or unknown solution) in a test tube. ... b. Add 10 drops of 0.1 M silver nitrate, AgNO3. ... e. Add 0.5 mL 6 M ammonia, NH3, to the precipitate. ... ...
Ionic compounds such a sodium chloride and polar covalently bonded molecules such as ammonia dissolve in polar solvents such as water. Non-polar molecules such as fats and oils dissolve in non-polar solvents such as carbon tetrachloride. Organic molecules such as oils will separate out when mixed...
(Lolium perenne)-dominated pastures, in a simulated rotational grazing approach over two consecutive growing seasons. Annual N application rates were 0, 140 and 280 kg N ha−1. The phenological development of perennial ryegrass was the main driver of CGR, N uptake and most PFTs. The effect ...
The role of trade in GVCs-related intermediate goods is weak. Most of the final products on the global value chain are processed and assembled before they flow to the final consumer countries. This process requires a lot of labor. Therefore, changes in the trade situation have a greater ...
Following this, scholars have divided the Porter hypothesis into “strong” and “weak”, where “strong” denotes that the innovation compensation effect may entirely offset compliance costs, and “weak” denotes that it can only partially do so [29]. A non-linear relationship characterizes the ...
