2. Reactivity: Alkali metals are highly reactive, especially with water and halogens. Their reactivity increases down the group from lithium to francium. 3. Electron Configuration: Alkali metals have one electron in their outermost shell (valence shell). They readily lose this electron to form cat...
Describe some uses of lithium and its compounds. How can Nitrogen and Oxygen form Nitrogen dioxide if both Nitrogen and Oxygen have a negative charge? Describe lipids. Explain how nitrogen/phosphorus GC detector works. Describe the water and carbon cycle. How do they contribute to climate change...
On the other hand, when a reactant releases one or more electrons and gets converted to another compound, we say that this reactant has been oxidized. The reaction in which one reactant gets reduced and another gets oxidized is known as an oxidation-reduction reaction or redox reaction....
Describe the components and operation of a concentration cell, including what distinguishes them from other types of galvanic cells. Include all necessary parts of the cell and the purpose of each. How does a buffer work? Explain what is the meaning of activation energy of a chemical reaction. ...
What are the major advantages and disadvantages of fusion as a potential energy source compared with fission? What is the major technical problem that must be solved to permit the development of a fusion reactor? What are some of the advantages and disadvantages of using lithium-ion b...
The present form of periodic table is helpful to the students of chemistry in a way that they can corelate or compare the different properties of different elements from this table and they can actually study the elements properly from this table....
Combustion ReactionCombustion is one such process. In combustion, a substance reacts with the molecules of oxygen very quickly. The resultant products are carbon dioxide plus water in addition to lots of heat energy. In a combustion process, the hydrocarbons lose their property completely to ...
Describe in general terms how chemists can follow the character of a reacting molecule using lasers. Define inorganic chemistry and explain the fundamentals of inorganic chemistry. List 3 each physical and chemical characteristics of water and explain them briefly. Define what a chemical reaction is ...
Explain why a well-mixed column of gas is warmer on the bottom. Why are resonance structures inaccurate? Give an example. Why is the formation of a solid evidence of a chemical reaction? Use a molecular-level drawing in the explanation. Describe and explain the possible effect o...
Allotropes of Sulfur:Sulfur atom forms a large number of allotropes that means it is found in nature in different structure with same physical state. The allotropes are inter convertible according to their thermal stability.Answer and Explanation: There are so many...
