- Q: and what are the kinds of organic compounds?..pls. help me abt. this..thanks!..(^_^)
- Any carbon-containing compound is considered organic with the exception of carbonates, bicarbonates, carbon dioxide and carbon monoxide.
- Q: Such as sulfuric acid, carbonic acid. The The thank you very much
- Dilute hydrochloric acid
- Q: give me at least 5 substances
- Organic: methane CH4, propanone CH3COCH3, glucose C6H12O6, ethanol CH3CH2OH, ethene C2H4 Inorganic: CO2, SO3, NO, NO2, SO2 Acid: HCl, HNO3, H2SO4, HCOOH, H2CO3 Base: NaOH, KOH, CaO, CaCO3, MgO Salt: NaCl, KCl, MgCl2, CaCl2, KBr
- Q: How to add inorganic salts
- Helicobacter pylori can cause a variety of stomach problems, including gastritis, gastric ulcer, duodenal ulcer, non-ulcerative indigestion, gastric cancer. Therefore, the eradication of Helicobacter pylori has become an important measure for the treatment of modern gastrointestinal diseases. To identify patients with Helicobacter pylori infection, the clinical need for a high sensitivity, specificity, fast, simple, safe, inexpensive Hp diagnostic method, that is, carbon 14 breath test. The examination and painless, noninvasive, fast and simple, no cross the advantages of infection, experts at home and abroad have been recommended for the diagnosis of Hp gold standard, has been widely used in clinical practice.
- Q: How to isolate the effects of inorganic salts on enzyme solubility
- Most enzymes are proteins, and high concentrations of inorganic salts can denature the protein and precipitate. The enzyme can be separated by this principle.
- 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: Does the mixture have a simple substance? What is it?
- Of course there are myself! Such as red phosphorus and white phosphorus mixture, white tin and gray tin mixture, oxygen and ozone mixture, etc., anyway, there are a lot of it! Usually pay attention to accumulation. I hope that my answer is helpful to you and wish you good results!
- Q: Calcium is not an inorganic salt
- Calcium salt is determined whether it is inorganic salt depends on its acid, if it is organic acid synthesis of calcium salt is organic salt, if it is inorganic acid synthesis of calcium salt is inorganic salt. The main basis for determining the inorganic salts is whether or not organic reactants are involved in the formation process.
- Q: would heterotrophic organism grow well in inorganic salt media? why or why not?
- No. Heterotrophs get energy from the environment in the form of chemical bonds within organic molecules (such as glucose). An inorganic salt medium would not supply the needed organic molecules. Your heterotroph would starve.
- Q: My body fat rate 14.6 normal body fat percentage 31.2 is more than the normal value I do not know the difference between the two please God answer ah Thank you very grateful and then those elements of my lack of God is the situation ah I love meat is not a vegetarian! And I super love to eat eggs! And my super love to drink water!
