- Q:How to do it? Solve Inorganic Chemistry
- Inorganic chemistry is one of the earliest disciplines in the development of chemical science. It undertakes a major task of studying the composition, structure, properties and reactions of all elements and elements (except hydrocarbons and derivatives). The current development of inorganic chemistry has two distinct trends, that is, in the breadth of the broadening and depth of the advance. It is the three pillars of modern civilization
- Q:Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?
- No, aldehyde is functional group, must be aldehyde for the mother. In addition, when the aldehyde group is a substituent, it is named as a formyl group.
- Q:What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
- Halide only fluoride in normal temperature and pressure may be gaseous;
- Q:Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even
- The number of hydrogen atoms in the hydrocarbons containing carbon, oxygen and oxygen is also even.
- Q:What is the relationship between hydrocarbon and hydrocarbon derivatives?
- The hydrocarbon is the parent of the organic compound, and the other various organic compounds can be regarded as derivatives of one or more hydrogen atoms in the hydrocarbon molecule being replaced by atoms or radicals of other elements.
- Q:What is the most primitive person on earth?
- The process of organic life is roughly divided into three steps: first the original earth simple inorganic compounds to form the original organic matter (hydrocarbons and its simplest derivatives), the second is based on the first step, gradually developed into a complex Organic compounds (sugars, nucleotides, amino acids) and their polymer polysaccharides, nucleic acids and proteins, as well as other organic substances, and the third is that with the evolution of natural conditions on Earth, the above substances are complex interactions, resulting in a metabolic Characteristics, can grow, reproduce, inheritance, variation of the original organic organisms.
- Q:What is the definition of organic matter
- Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
- Q:Other corals are because the color of the corals show colorful, why only the red coral is the exception of it? did not find the reasons for the big god to explain
- Calcium coral is the main component of calcium carbonate, in addition to about 3% of magnesium carbonate and 1.5% to 4% of organic matter, and trace amounts of silicon and iron. The presence of organic matter increases the toughness of corals, making it better for processing and polishing. Calcium coral colors are mostly white or gray, but when it contains a considerable amount of different impurities, it is possible to show red, pink, orange, yellow, blue, purple and other colors. Therefore, by the living environment and many other factors, the same kind of coral can have different colors, and different types of corals and stars showing the same color. Red coral is really because of carotene.
- Q:What is "organic" and "inorganic" in chemistry?
- Carbon compounds, not carbon oxides, carbonates, bicarbonates are organic matter
- Q:Are all carbon compounds all organic?
- Not ah, like CO, CO2, carbonated, carbonate is not ah
