A salt dissolves in water to form a green solution. A precipitation is formed when the aqueous solution is treated with buffer NH4C/NH3 and thioacetamine.
Question- Write the balanced equation for the reduction of 2,6 dimethylnitrobenzene to give 2,6-dimethylaniline using stannous chloride, snCl2 in concentrated hydrochloric acid
If you have 4.14 g of caffeine dissolved in 61.0 mL of water and the extraction coefficient between H2O and CH2Cl2 is 21.51. How many grams of caffeine will extract into the CH22Cl2 layer if you use 96.9 mL
From this fact, we can deduce that a column of air one square inch in cross-section, measured from sea level to the top of the atmosphere, would weigh approximately 14.7 lb. Given that air has an average molar mass of 28.97 g, calculate the number..
Magnesium nitride (Mg3N2) is formed by the reaction of magnesium metal (Mg) with nitrogen gas (N2). No other products are produced. (A) How many grams of magnesium nitride can be made in the reaction of 35.00 g of magnesium and 15.00 g of nitrogen..
Determine the molar solubility of Mg(OH)2(s) (Ksp = 7.1 x 10-12) in a 0.050 M solution of NaOH both neglecting activities and including activities. Compute the percent relative error introduced to the calculation when you omit activities.
