Solid calcium oxide reacts vigorously with water to form calcium hydroxide accompanied by liberation of heat. This process is called slaking of lime. Calcium hydroxide dissolves in water to form its solution called lime water. Which among the following are true about slaking of lime and the sol...
Diphenyl methane & diphenyl toluene are useful drug & pesticide intermediates, the reaction which uses the conventional AlCl3 as the catalyst has several pollution problems & the reaction proceeds vigorously and is dangerous. Chemicals: Aluminium chloride and ferric chloride were obtained from s.d. ...
(ethylene oxide) can then be added slowly, alternating between small additions of liquid and dry materials, shaking vigorously between each combination. Next a salt such as a LiClCO4salt can be added and the composition shaken once again. Finally, a second solvent, such as trichloroethylene, ...
Procedure: The coating solution is prepared by adding HP 55S to ethanol and acetone stirring vigorously in a large beaker. The mixture is allowed to stir until the HP 55S has gone into solution completely. Triethyl Citrate is then added and stirred further to obtain the final solution used ...
Then, acetone (10 mL) was added, and the mixture was vigorously stirred (1200 rpm), which caused the precipitation of a fluffy brown solid over the next 20 min. The solid was then filtered, affording 628 mg of pure bsmim (49% yield). 1,3-Bis(sulfomethyl)imidazole (bsmim, 1): ...
This sample is then added to 100 mL distilled water at 40 °C and vigorously soaked for 20 s, after which it is placed in an electric oven at 40 °C for four days. After, it is filtered under vacuum conditions and then analyzed via titration to quantify both [OH]− and [Ca]2+ ...
Strengthen energy-conservation management, followed by legislation and the enforcement of energy conservation and environmental protection laws: Vigorously promote the technological innovation of the pottery industry, and develop and popularize new energy-saving products. Formulate energy-consumption standards for...
The proper amounts of each solution (calculated based on the chosen molar ratio of monomeric units in the resulting C-ZnDOPs) were weighed into a single beaker and vigorously mixed for 1 h at room temperature. Afterwards, the mixture was concentrated on a rotary evaporator at 60 °C and ...
