4. a. A sample of a CaCI 2HO/K C,0, HO solid salt mixture is dissolved in -150 mL of deionized water previously adjusted to a pH that is basic. The precipitate, after having been filtered, was air-dried and weighed. Data for Trial I were obtained as shown. Complete the following table. (See Report Sheet.) Record calculated values with the cor- rect number of significant figures. A. Precipitation of CaC,0,H from the Calculation Zone Salt Mixture 3. Mass of salt mixture...

estion is: A 1.276 g mixture of the solid salts Nm,SO. (142.04 g/mol) and Pb(NO3)2 (331.18 g/mol) foms an aqueous solution with the precipitation of PSOE (303.26 /mol). The precipitate was filtered and dried, and its mass was determined to be 0.717. The limiting reactant was determined to be Na SO (4 mark) A. Write the net lonic equation B. What is the percent by mass of each salt in the mixture?
6. A 1.500 g sample of a mixture of solid Na PO, 12H.O mixed with NaCl, was dissolved in water, reacted with aqueous 1 M SrCl, and 0.520 g Sr.(PO), precipitate was collected and dried to a constant mass. If the reagent tests demonstrated that Na PO:12H.O was the limiting reactant in the precipitation reaction, calculate the mass percent of Na PO, 12H 0 in the original sample. a. How many moles of Sr,(PO), were produced? b. What is the...
Please answer 6a through 6e.
Thank you!

Based on the data, please answer question 3 (a,b, and c).
thank you!

Unsure of how to do question 3 a. "based on the number of
moles of each reactant you started with, determine which was the
limiting reactant. what is the excess reactant. please show
detailed work, thank you!!

pl#3 QUESTION 1 A mixture of 0.810g of BaCl 2.2H 2O and Na 2SO 4 produces 0.466g of BaSO 4, the limiting reactant in the reaction is Na 2SO 4. Calculate the percent of BaCl 2.2H 2O and Na 2SO 4 in the original mixture. QUESTION 2 Because of the finely divided nature of the Ba 3(PO 4) 2 precipitate, some of it passes through the filter and is not collected. How does this loss of precipitate affect the reported...
