If air's density is 1.29 g/l define what three gaseous elements if place in a balloon would cause the balloon to rise in air as well as what three elements would cause the balloon to sink in air?
Liquid acetone was placed in a 3.00L flask, then vaporized at 95'C and 1.02 atm. The vapor filling the flask weighed 5.87g. Calculate the molar mass of acetone.
AgI is more soluble in ammonia than in pure water. Calculate molar solubility of AgI in 0.80 M NH3 solution. Ksp(AgI)=8.5*10^-17, Kf=1.6*10^7 for Ag(NH3)2.
What mimimum hydronium ion concentration (M) would be needed to prevent precipitation of cupric hydroxide (Cu(OH)2 Cu2+ + 2OH- , Ksp = 2.2 x 10-20) from a solution containing 0.010 M Cu2+ ion?
Describe simple chemical tests that would enable you to distinguish between the following sets of compounds. Write equations for any chemical reactions
Give the systematic names for the formulas, or the formulas for the names. (Type your answer using the format copper(II) chloride for CuCl2, and using the format CO2 for CO2. Omit the centered dot for hydrates.)
