Q:CO is simple?

Is a compound, not a substance

Q:Why is the inorganic salt left after the burning of the food

Food contains protein, fat, inorganic salts and water and other substances in the process of combustion in addition to inorganic salts and the rest of the water are burned, and water in the combustion process evaporates. So take the only inorganic salt.

Q:Finished homework, why the neck acid

Mainly due to the study of stress more time and time of excessive learning and fatigue and other reasons into the current situation of the back of the neck pain

Q:A. food gathering and digestion B. photosynthesis and diatom structures C. reproduction and osmosis D. wave and current motions

its not a so try b or c those 2 are the most likely to be the right answers

Q:Sodiumcorbonate is inorganic salt , why it is not organic substance even it contains carbon?

Na2CO3 is joined by ionic bond not covalent C-C bond in organic molecules. @the other answerer: LOL! maybe i should expect a TD, too. Another problem with this section is students know how to ask but never know how to say thank you. Rarely do i see an asker selecting a BA. If i see one who does, whether i get the BA or not, i will definitely answer another question from that person.

Q:Such as sulfuric acid, carbonic acid. The The thank you very much

Dilute hydrochloric acid

Q:what is the function of salts in DNA extraction?

DNA can be purified for DNA sequencing or for restriction digestion by precipitation in an alcohol/water mixture in the presence of a high concentration of inorganic salt. DNA is recovered from the aqueous solution by addition of salt to final concentrations of 0.8M LiCl, 0.3-0.5M NaCl, NaOAc, or 2.5M NH4Ac and an appropriate volume of alcohol (30%-50% final percentage isopropanol; 60%-80% final percentage ethanol), storage for a brief period of time at -20°C or -70°C, followed by centrifugation. Subsequent desalting of the DNA pellet involves rinsing in 70% alcohol, recentrifugation and re-suspension in appropriate buffer.

Q:How can experiments prove that there are inorganic salts in the leaves of plants

The experimental leaves used to dry, crushed into powder or sintered ash, and then the analysis of mineral elements, we can learn.

Q:Acidic oxide is a kind of oxide which can form acid or react with water to form salt and water. Generally non-metallic elements of oxides and certain transition metal elements of high-priced oxide. Such as sulfur trioxide SO3, phosphorus pentoxide P2O5, manganese dioxide Mn2O7, chromium trioxide CrO3 and so on. Most of the non-metallic oxides are acidic oxides. In our familiar non-metallic oxides, carbon monoxide and nitric oxide are not acidic oxides, and are usually classified as non-acid oxides.

Q:Alkali soda water

Soda water is an aqueous solution of sodium bicarbonate, containing weakly alkaline, medical topical disinfectant, drinking and neutralizing the body's acid-base balance, changing the acidic constitution. Most of the soda water sold on the market is a synthetic carbonated beverage that is compressed into purified water and added sweeteners and fragrances. Soda water is a carbonated beverage, is pressed into purified drinking water into carbon dioxide, and add sweeteners and spices. He is an aqueous solution of sodium bicarbonate, containing weakly alkaline, medical topical sterilization, oral administration can be integrated within the body's acid-base balance, change the acidic body. Sodium bicarbonate is what we say baking soda molecular formula NaHCO3 is usually said that the surface screwdriver, but this is not directly joined the surface screwdriver, the market selling soda water is mostly in the purified drinking water into the carbon dioxide, and add Sweeteners and fragrances of synthetic synthetic carbonated beverages. Baking soda: NA2CO3 soda: NAHCO3, weak base. Medical topical disinfection can be sterilization, oral administration can cure too much acid. Soda water is actually carbonated water Well, Coke, whiskey what is inside. Pure soda water also has, usually the equipment, supermarkets have to sell. Can be used for cocktails. Can go to the pharmacy to buy small soda tablets with warm water to the system, but the concentration is not good to master.
