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:What is the difference between hot and cold asphalt?

Grandmother next door aunt is the street to sell stewed meat, a child often see her burning a pot of hot asphalt pork hair, black asphalt boiled immediately leaching in the meat, and so dry quickly pull it down, pork will Change very clean and white, clean the meat will be directly thrown into the pot halogen system, this method relative to the traditional plucking save time and effort a lot. Here, please bloggers blame me to come to funny, because the end of the story is not funny, that aunt's little sister in the sixth grade when suffering from leukemia away, adults say with her home burning asphalt There are relationships, eighteen years later, and she only a few side of the edge of the I actually remember the full name of her sister, her looks, the tone of her voice, we played the game and we were a very curious In the asphalt pot to see the scene of pig hair ... ... hope that each parents do not ignore the child's growth in the small problem.

Q:Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?

I think that can be said so.

Q:Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?

Aromatic hydrocarbons referred to as "aromatic", usually refers to the molecules containing benzene ring structure of hydrocarbons. Is a kind of closed-chain class.

Q:Are the asphalt and peat kinds of vegetables have heavy metal?

Asphalt is a hydrophobic material, it is impermeable, and almost insoluble in water, acetone, ether, dilute ethanol, dissolved in carbon disulfide, carbon tetrachloride, sodium hydroxide.

Q:Why can organic matter be unique in chemical substances? What is the nature of the C atom?

Carbon, and can be spun, sp2, sp3 hybrid, so CH, CC, CO, CN, C = C, C = O, C = N and other covalent bonds can be formed and the key size is moderate, So these keys can also be more easily broken and generate new compounds. For silicon, the type of hybrid is mainly sp3 (no O = Si = O this molecule exists), but the Si-O bond bond energy is greater than Si-C, Si-Si, Si-H, so these keys are It is easy to break to produce SiO2, so there is the most natural Si-O compounds, and this compound is very stable, difficult to break down or other reactions.

Q:Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not

As long as carbon and carbon double bonds and three hydrocarbons can be hydrocarbons

Q:What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?

Oxygenated derivatives are: methyl ether, methyl ethyl ether, formaldehyde, ethylene oxide;

Q:What is "organic" and "inorganic" in chemistry?

Inorganic compounds are inorganic compounds, usually refers to non-carbon compounds. , Alkali, salt and so on.

Q:Why the silicon hydride less, a lot of hydrocarbons. (Why did not you find silicon-based creatures) and why are so many oxides of silicon, little carbon oxides?

You know silane bar, SiH4, this thing will be spontaneous, very unstable
