How do you calculate/what formula do you use when trying to determine any general type of chemical concentration using chemical stoichiometry?
Calculate the grams of calcium carbonate that could be formed from the reaction of 14.5 g of calcium oxide with 12.0 grams of carbon dioxide. If 15.3 g of calcium carbonate are actually formed, what is the percent yield?
essentially converted to Cu(NH3)4 2+ ion, the voltage of the cell (E) goes up to 0.883 V and the Cu electrode is still negative. Find the residual concentration of Cu2+ ion in the cell.
In a reacting mixture K is the ratio of product to reactant concentrations. If Q
Problem- Using the value of Ksp for Ag2S, Ka1 and Ka2 for H2S, and Kf = 1.1 105 for AgCl2-, calculate the equilibrium constant for the following reaction. Ag2S(s) + 4 Cl-(aq) + 2 H+(aq) 2 AgCl2-(aq) + H2S(aq)
