What did Justus von Liebig invent?
Benzilic acid rearrangementJustus von Liebig / InventionsThe benzilic acid rearrangement is formally the 1,2-rearrangement of 1,2-diketones to form α-hydroxy–carboxylic acids using a base.

Why did Justus von Liebig invent the mirror?
Justus von Liebig did not invent mirrors, as the archaeological record will prove to predate von Liebig’s life. Instead, the German chemist developed a chemical reaction to easily affix a thin sheet of silver to the glass of a mirror.
What did Justus von Liebig said in terms of maintaining soil fertility?
What did Justus von Liebig said in terms of maintaining soil fertility? Through Liebig’s experimental work, he also established the famous “law of the minimum,” that states that plant growth is constrained by the least available nutrient in the soil.
What is humus theory?
It was the period in which the nutrition of plants commonly was explained with the so-called humus theory. This theory stated that plants lived on humus-derived extracts (in German Extraktivstoff) containing simple water-soluble compounds of C, H, O, and N from which they were able to rebuild more complex plant tissue.
Who was Justus von Liebig and what role did he play in the development of agriculture?

Who Found mirror?
chemist Justus von Liebig
A discovery by the great German chemist Justus von Liebig in 1835 made mirrors widely available. Liebig found a way to coat glass with a thin layer of metallic silver by depositing the metal directly by means of a chemical reaction.
What is Justus von Liebig law of minimum?
Liebig’s Law of the Minimum states that the local yield of terrestrial plants should be limited by the nutrient that is present in the environment in the least quantity relative to its demands for plant growth, and this statement has been confirmed worldwide.
What is humus short answer?
Humus is dark, organic material that forms in soil when plant and animal matter decays. When plants drop leaves, twigs, and other material to the ground, it piles up. 6 – 12+
