Why are the two words "alkaline" and "earth" used to name the group 2 metals? What are alkali metals and alkaline earth metals? Describe their properties and give examples of each. Why are anions always larger than the atoms from which they are formed?
Do the alkali metals tend to gain or lose electrons in chemical reactions? What are oxidation numbers used for? Is hydrogen reactive? What is the oxidation number of chlorine in NaClO4? What is the oxidation number of the oxygen atom in H2O2?
Assertion :The alkali metals are strong oxidizing agents. Reason: The one electron in their valence shell is easily lost. View Solution Q4 Which of the following compound is formed when Sodium thiosulphate reacts with some strong oxidizing agents: (i.e.,dichromate so...
Our experiments show that the dehydration of natural antigorite serpentinite at shallow subduction zone conditions (1 GPa, 800°C) produces moderately oxidizing fluids (QFM+2) with elevated concentrations of Na, K, Ca, and Mg. The composition and redox of the experimental fluids are then used ...
aAOP are defined as those processes that use strong oxidizing agents (H2O2, Fenton’s reagent) or heterogenous photocatalysts such as TiO2,ZnO2, Mn and Fe in the presence or absence of an irradiation source AOP被定义成在出现或缺乏使用强的氧化剂的那些过程(水2, Fenton的试剂)或异种photocatalysts...
Microwaves travel in matter in the same manner as light waves: they are reflected by metals, absorbed by some dielectric materials and transmitted without significant losses through other materials. For example, water, carbon, foods with a high water, some organic solvents are good microwave ...
The base may be separated from the solution by means of an alkali, for example, ammonia. Example 2 1.8 parts of a:p-di- [N-benzyl-benzimidazyl(2) ]-ethane (obtainable in the usual manner by the treatment of a:p-di-[benzimidazyl-(2) ]ethane with benzyl chloride) are dissolved ...
