Question

Please show complete steps and work. 1. In the lab 2.000 L of a 0.0250 M H2SO4 solution was prepared by using 150.00 mL of a stock solution and adding 1.850 L of water. What was the concentration of the stock solution? (MM: H2SO4 = 98.078 g/mol). 2. A solution was prepared by taking a large scoop of BaCl2(s) and dissolving in 350.0 mL of water. A 30.00 mL portion of this solution was found to require 24.62 mL of 0.1250 M H3PO4 in order to consume all the barium ions. a. Write a balanced equation for this reaction. b. What is the concentration of the BaCl2 solution? c. How many grams of BaCl2(s) were used to make the solution? (MM's: BaCl2 = 208.233; H3PO4 = 97.994 g/mol). 3. Predict the products, if any, and write the balanced molecular equation and the balanced net ionic equation for each of the following. (Assume that all reactions occur in aqueous solutions) a. Ferric carbonate plus hydrobromic acid. b. Cesium bromide plus plumbous nitrate. c. Perchloric acid + cadmium hydroxide --> d. Sr(OH)2 + Fe2(SO4)3 ---> e. NH4BrO2 + Zn(C2H3O2)2 --->
