Calculate the molecular formula of diazomethane, assuming thecompound is 28.6% C, 4.8% H, and 66.6% N by mass and the density ofthe gas is 1.72 g/L at 250C and 1.00 atm.
The confirmation test for Ag^+ is to add HNO3 to the [Ag(NH3)2] ^+ and see if a precipitate of AgCl forms. Where does the Cl ^ - come from. Why does adding HNO3 make AgCl precipitate
