Selected answers

KS test, named after Kolmogorov and Smirnov, two Soviet mathematicians, is a goodness of fit test. KS test judges whether the observation results of the sample come from the population of the specified distribution by analyzing the difference between the two distributions.

KS test does not need to know the distribution of data, and can be regarded as a non parametric test method. Of course, the cost of such convenience is that the sensitivity of KS test is not as high as that of the corresponding test when the distribution of the test data conforms to a specific distribution. When the sample size is small, KS test is the most common nonparametric test to analyze whether two groups of data are different.

Is esterification reversible

Lonely Butterfly Shadow

Esterification is a reversible reaction. Esterification is carried out in concentrated sulfuric acid, and the generated ester will be hydrolyzed under acidic conditions, so it is a reversible reaction. Esterification is a kind of organic chemical reaction, which is the reaction of alcohol with carboxylic acid or oxygen-containing inorganic acid to form ester and water. It can be divided into three types: reaction of carboxylic acid with alcohol, reaction of inorganic oxyacid with alcohol and reaction of inorganic strong acid with alcohol.
Organic chemistry, also known as the chemistry of carbon compounds, is a science that studies the composition, structure, properties, preparation methods and applications of organic compounds. It is an extremely important branch of chemistry. Carbonaceous compounds are called organic compounds because chemists in the past believed that such substances must be produced by living things (organisms); However, in 1828, German chemist Friedrich Weiler successfully synthesized urea (a biological molecule) for the first time in the laboratory. Since then, organic chemistry has broken away from the traditional definition and expanded to the chemistry of hydrocarbons and their derivatives.

Is Jingwei Reclamation a Folk Story

Jingwei Reclamation is one of the ancient Chinese myths and legends. According to legend, Jingwei was the youngest daughter of Emperor Yan's Shennong. Her name was Nuwa.

Not only that, "Jingwei reclamation" also belongs to the revenge myth. Nuwa had no grievances with the sea before she died, but she accidentally drowned. Thus, she formed hatred with the sea and turned into a lifelong revenge cause for birds to reclaim the sea.
