D) If the same volume of each sample was taken, then more base solution would be required to neutralize the one with lower concentration. 1. Step 1 of 4 (a) The system initially contains and solid, which dissolves in water and gives ions. Compound. Step 2: Calculate moles of AgBr present 42.7 g AgBr x 1 mole AgBr/187.8 g = 0.227 moles AgBr Step 3: Use the mole ratio of the balanced equation to calculate moles Na 2 S 2 O 3 needed The mole ratio of Na 2 S 2 O 3 to AgBr is 2:1 0.227 moles AgBr x 2 moles Na 2 S 2 O 3 / mole AgBr = 0.454 moles Na2S2O3 needed (answer to part 1) on treating with cl2, the agbr is converted to agcl, and the total weight of agcl becomes 0.4269 gram. A) There is no chemical method designed to tell the two solutions apart. When the mass ratio of Ag 3 PO 4 in the La 2 Ti 2 O 7 /Ag 3 PO 4 catalyst was 50%, the degradation rate constant of Rhodamine B (RhB), methyl orange (MO), chloroquine phosphate (CQ), tetracycline . answer choices 53.6 g 1.44 g 1.23 g 34.5 g Question 3 120 seconds Q. Ag+ (aq) + Br (aq) + AgBr (s) Keq = 1.87 x 1012 Calculate the mass of AgBr formed and the concentrations of Ag+ and Br remaining in the equilibrium solution if 0.500 L of 1.00 M AgNO, and 0.500 L of 1.00 M KBr are mixed. 2021-2022 Grand Hope.
