Tip: don't waste your points on something you can plug into Google (Wikipedia) and get a pic of the stuff! Both CaSO4 and AgCl will precipitate from solution. If the temperature of the system is raised, the reaction heat cannot dissipate and the equilibrium will regress towards the left according to Le Chatelier principle. A precipitate of $\ce{CaSO4}$ is formed. Assume no loss of heat to the, Consider the dissolution of CaCl2. In the triangular sheet given PQ=QR=`l` . (please answer it in about 300 words). What are the advantages and disadvantages of high versus low administrative intensity? In one row of your spot plate, add five drops of the sodium hydroxide solution to each of four deprssions. I guess what I'm asking is what happened to the Cl^- and why, how many grams of NaOh are needed to make 50 g of Na3PO4 according to the equation: 3NaOH+H3PO4=Na3PO4+3H2O (i'm not sure where to even start for this! My planet has a long period orbit. Up to the 1970s, commercial quantities of sulfuric acid were produced in Whitehaven (Cumbria, UK) from anhydrous calcium sulfate. 3 CaCl2(aq) + 2 Na3PO4(aq) → Ca3(PO4)2(s) + 6 NaCl(aq), Consider a solution that contains Ag+ , Ba2+, and Pb2+ each at a concentration of .2M a) You add NaCl until the concentration of Cl- is 5.0 x 10^-3 M. A white precipitate forms. To start let's convert the volumes to liters. Make sure the final answer is in the correct number of sig figs.
