Q: Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds: An ionic compound consisting of a cation and an anion. Active metals (such as sodium, potassium, calcium, magnesium, etc.) and active non-metallic (such as fluorine, chlorine, oxygen, sulfur, etc.) when the combination of active metal loss of electrons to form positively charged cations (such as Na +, K +, Ca2 + (Such as F-, Cl-, O2-, S2-, etc.), cations and anions are formed by electrostatic interactions to form ionic compounds. For example, sodium chloride is an ionic compound consisting of positively charged sodium ions (Na +) and negatively charged chloride ions (Cl-). Many bases (such as NaOH, KOH, Ba (OH) 2, etc.) and salts (such as CaCl2, KNO3, CuSO4, etc.) are ionic compounds. The total number of positive charges in the cationic compound is equal to the total number of negative charges carried by the anion, and the whole compound is electrically neutral. Most ionic compounds can not be conductive in solid (or crystalline), while their aqueous or molten state can be conductive. The ionic compounds generally have a higher melting point and higher boiling point, higher hardness, crisp and difficult to compress, and the highly volatile ionic compounds are linked by ionic bonds, without independent structures, such as sodium chloride.

Q: Sugar, fat, and so on a variety of organic matter is full of different units of the heat of the small box. (Save the heat the most efficient, the least loss of heat the most practical and most economical box).: Organic matter carries more richer and more easily utilized by creatures

Q: Are the asphalt and peat kinds of vegetables have heavy metal?: Asphalt and its flue gas on the skin and mucous membranes are irritating, phototoxic and carcinogenic effects. China's three major asphalt toxicity: coal tar pitch> shale asphalt> petroleum asphalt, the former two are carcinogenic. Asphalt main skin lesions are: phototoxic dermatitis, skin lesions limited to the face, neck and other exposed parts; black disease, skin lesions are often symmetrical distribution in the exposed parts, was flaky, brown - dark brown - brown black; Acne; verrucous vegetation and heat burns caused by accidents. In addition, there are dizziness, head swelling, headache, chest tightness, fatigue, nausea, loss of appetite and other systemic symptoms and eye, nose, throat irritation symptoms.

Q: Identification of Derivatives of Chemical Hydrocarbons in High School: Derivatives have gone, and give a specific range Well

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: Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong: Correct

Q: What are the characteristics of organic compounds?: Organic compounds are usually referred to as carbon-containing compounds, or hydrocarbon-containing compounds and their derivatives are collectively referred to as organic matter. Organic compounds are generally insoluble in water and soluble in organic solvents with lower melting points. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects, and there are many kinds of organic compounds, which can be divided into two major categories of hydrocarbon and hydrocarbon derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.

Q: Inorganic chemistry employment direction? Current research direction: Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic matter, which is the oldest branch of chemistry. Inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds. (In addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.) Inorganic chemistry is in addition to hydrocarbons and their derivatives, the nature of all elements and their compounds And their reaction to experimental research and theoretical interpretation of science, is the development of the discipline of the earliest branch of a discipline.

Q: Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons: Pro-butylbenzene ethane

Q: Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?: Hydrocarbons and hydrocarbon derivatives
