If you're talking about concentrated sulfuric acid, then the white powder can't be organic because it's carbonized, and it can't be a metal powder because it's displacenting and dangerous. It could be salt, like calcium sulfate, and preferably acid, and if it's chloride, HCl may come out. The above is for reference only.

It cannot be dissolved in water. Considering that it may be dissolved by water, it is not sure what it is. Is this white powder inorganic?
Sulfuric acid (chemical formula: H2SO4), the most important oxygenated acid of sulfur. Anhydrous sulfuric acid is a colorless oily liquid, when crystallized, it is usually used in various concentrations of aqueous solutions, using the tower method and contact method.
The former is crude dilute sulfuric acid, and the mass fraction is generally about 75%; The latter can obtain concentrated sulfuric acid with a mass fraction of 338 and a relative density.
Sulfuric acid is one of the most reactive binary inorganic acids that reacts with most metals. High concentration of sulfuric acid has strong water absorption, can be used as a dehydrating agent, carbonized wood, paper, cotton and linen fabrics and biological skin and other carbohydrate-containing substances. When mixed with water, a large amount of heat energy is also emitted.
It is highly corrosive and oxidizing, so it should be used with caution. It is an important industrial raw material, which can be used to make fertilizers, medicines, explosives, pigments, detergents, batteries, etc., and is also widely used in purifying petroleum, metal smelting and dyes and other industries. It is often used as a chemical reagent and can be used as a dehydrating agent and sulfonating agent in organic synthesis.

What is a white dough that mixes sulfuric acid? It's oxidized, right?

Barium sulfate and lead sulfate are white solid powders, which are very stable to sulfuric acid and do not affect the chemical properties of sulfuric acid. Titanium dioxide is stable to dilute sulfuric acid, but hot concentrated sulfuric acid is not.

Calcium hydroxide is a white powdery solid. The chemical formula Ca(OH)2, commonly known as hydrated lime and slaked lime, is added to water, and it is in two layers, the upper layer of aqueous solution is called clarified lime water, and the lower layer of turbidity is called lime milk or lime slurry. The upper layer of liquid clarified lime water can be used to test carbon dioxide, and the lower layer of turbid liquid lime milk is a building material.
Calcium hydroxide is a white powdery solid that is slightly soluble in water. Calcium hydroxide is a binary strong alkali, which has the general properties of alkali and is a strong alkali, which is corrosive to ** and fabrics. Calcium hydroxide has a wide range of applications in industry.
The white powder, which is produced by the reaction of quicklime and water, and its saturated aqueous solution is called lime water. It is a commonly used building material, and is also used as a fungicide and chemical raw materials.

One is curioseness. Rare items, such as Chinese calligraphy and painting, old porcelain, rare books, antiques and miscellaneous and other antique cultural relics and artworks. These works of art have a long history, and there are very few surviving at present, and the many people who like them are easy to form the conditions for the existence of auction competition. >>>More

The alignment is used to draw an ellipse, so there is no such line on the diagram. When learning the ellipse, there is a principle I don't know if the landlord remembers, as shown in the figure, two points (f1, f2) are connected by a rope, take the third point p on the rope casually, tighten the rope to make a circular motion at the vertex p, and the trajectory obtained is both an ellipse. >>>More
