18.7 mmol) to a solution of EDCI (3.95 g, 20.6 mmol) and triethylamine (2.87 mL, 20.6 mmol) in dichloromethane (360 mL), followed by stirring the reaction mixture for 18 hours at room temperature. The solution is then washed with saturated NaHCO3solution (2×100 mL) and water...
Epsom Salts (Magnesium sulfate chemical name) is used as a treatment against pre-term labor. You can use it to stop pre-term labor, but it will never be the cause of pre-term labor. Many women have safely flushed during pregnancy. Whenever making important decisions try to follow your gut...
Is sodium bicarbonate a solid, liquid, or gas? How is baking a cake a chemical reaction? How do you separate sodium carbonate and sodium bicarbonate? What happens when sodium bicarbonate is added to water? What happens when you mix vinegar and bicarbonate of soda?
The waste solid, bauxite tailings, is removed and aluminium hydroxide is precipitated from the remaining solution of sodium aluminate. This aluminium hydroxide can be converted to aluminium oxide or alumina by calcination. The residue or bauxite tailings, which is mostly iron oxide, is highly ...
Explain why methyl alcohol is soluble in water in all proportions, while stearyl alcohol CH3(CH2)16OH is a waxy solid that is not soluble in water. Explain the differences between the two drying agents, anhydrous magnesium sulfate and anhydrous sodium sulfate. Why does...
then separate the organic layer. Dry the organic layer with anhydrous magnesium sulfate, remove the solvent by rotary evaporation, and obtain a yellow needle-like solid. Dissolve the filter cake in a suitable amount of hot DMF, filter while hot, and rinse the filter cake with a small amount...
