Q:What is organic matter? Candle is organic?
For example: CH4 C2H6O and so are organic matter
Q:Are all carbon compounds all organic?
Of course not Like carbon monoxide is not friends ~ ~ ~ In general, organic matter will contain at least two elements of carbon and hydrogen, but carbon tetrachloride is an exception. Many of the concepts in chemistry, or else there is a special case, or that is limited, can only control the total but can not control the whole. It is very annoying thing oh ~ ~ ~
Q:NH4HCO3 and so have C atoms ah, why still inorganic
Organic definition is not all elements, if only look at carbon atoms, then graphite and carbon dioxide are also areas of organic matter, so this is not the case. In general, organic matter is defined as containing atomic elements, which can be combusted, low density, low melting point, strong volatility, poor solubility in water, etc., which are composed of carbon atoms and covalent bonds.
Q:What is the reason why the battery's energy density is much lower than the hydrocarbon?
The battery is carrying the oxidant, and the hydrocarbon is the air as an oxidant direct reaction, which is less than the rocket engine than the jet engine than the reasons for the red.
Q:How the most primitive life on earth is produced under what conditions
The most primitive creatures on earth are actually RNA, which is pulled earlier than any prokaryotic cells, and the eukaryotic cells are advanced, in short, the chemical reaction in the environment at that time.
Q:High school chemical hydrocarbons with hydrocarbon derivatives with water solubility
The amount of forgotten, just remember the carbon six rings
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:Are there two derivatives of equivalent hydrogen?
You give the scope is too broad, at least to set in what kind of functional group range ah.
Q:Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not
Should be able to ah and bromine water addition reaction and fade:
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;
