Sulphuric acid and chlorosulphonic acid react violently with water, the resulting reaction producing large amounts of heat which can cause the water to boil; ● 盐酸,氯丙酸,发烟硫酸均对呼吸道有毒性。 Chlorosulphonic acid, dichloropropionic acid, hydrochloric acid and oleum are toxic by inhalation;...
Which metal reacts most vigorously with water? (a) Al (b) Cs (c) Sr (d) Ba. How would you prepare the given substance from 2-cyclohexenone? More than one step may be needed. How would you prepare the given substance below from 2-cyclohexenone? More than one step may be needed. ...
Arrhenius plots used to analyse the effect of temperature on the rates of chemical reactions show that the temperature of the maximum reaction rate decreased with the increase in the number of atoms in the hydrocarbon reactant35. The main effect of hydrogenolysis is the cleavage of the ...
Which of the following metals will not react with sulfuric acid (H2SO4(aq)) by a single displacement reaction? a. silver b. zinc c. magnesium d. iron What is the reaction that occurs at a silver anode of a voltaic cell? A co...
Benzoyl chloride (C6H5COCl) reacts with benzene (C6H6) in the presence of aluminum chloride (AlCl3), which acts as a Lewis acid.- Process: 1. AlCl3 coordinates with the chlorine atom of benzoyl chloride, generating a highly reactive acylium ion (C6H5CO+). 2. The acylium ion then ...
Three or four pieces of granulated zinc and 100 mL of 40% caustic soda are added, and the flask is connected with the splash heads of the distillation apparatus. Next, 25 mL of 0.1 N sulfuric acid will be taken in the receiving flask and is then distilled. When two-thirds of the ...
Why does silver become tarnished (react with air), but gold doesn't? Would a fresh or stored egg coagulate quicker when exposed to heat? Explain. Is gold a conductor or a semiconductor? Explain. Why doesn't a gold atom have the same density as a go...
Salt: In our everyday language, we often think of salt as the table salt for cooking, which is sodium chloride (NaCl). However, more generally, salts are ionic compounds produced from acid-base reactions. Answer and Explanation:1 Option A is ...
1) impregnating alumina with an aqueous solution of zinc chloride, said solution also containing a small amount of nitric acid to give an impregnated alumina; 2) drying said impregnated alumina to give a dried impregnated alumina; 3) calcining said dried impregnated alumina to give a calcined imp...
react with the surface of the aluminum alloy sheet. The method of treating the aluminum alloy sheet is not particularly limited provided that a method which brings the treatment liquid into contact with the aluminum alloy sheet is used. That is, a usual method such as a roll coating method,...
