How many moles of sodium carbonate are contained in 200.00 mL of an 0.835 M solution of Na2CO3? 7. For the following reaction: 3 Cu(o+ 4 HNOs (a)3 Cu(NO,)2 (0)+2 NO20)+2 H20 What volume of 0.285 M HNOs is required for complete...
4 June 2019 CHEM 177-Su19 Chapter 4 APP-1 4. Hydrochloric acid (HCI) is generally sold as an 11.65 M solution. When doing titration experiments, many will use an HCl concentration of 1.00 M HCl. If you wanted to make 150 mL of 1.00 M HCI, how many mL of the stock HCl solution would you need? 5. A 4.00 L stock solution of H3PO4 of unknown concentration was mixed with 4.00 L of pure water. The concentration of the new...
50.0 mL of a stock solution of hydrochloric acid, HCl (aq), at 12.0 M is diluted by adding it to 150.0 mL of water, H2O. What is the concentration, in units of molarity, of the final, diluted solution?
The reaction between potassium dichromate and concentrated hydrochloric acid, produces a mixed aqueous solution of chromium(III) chloride and potassium chloride, and evolving gaseous chlorine. K2Cr2O7(s) + 14 HCl(aq) ⟶ 2 K+(aq) + 2 Cr3+(aq) + 8 Cl- (aq) + 7 H2O(l) + 3 Cl2(g) Suppose that 9.73 g of K2Cr2O7(s) react with concentrated HCl, and that the final volume of the solution is 124.3 mL. Calculate the final concentration of Cr3+(aq) produced: (Aside: also, think about and the number of...
If 0.050 mol hydrochloric acid (HCl) is mixed with 0.050 mol of sodium hydroxide (NaOH) in a "coffee cup" calorimeter, the temperature of 1.41 × 102 g of the resulting solution increases from 25.2°C to 31.3°C. If the specific heat of the solution is 1.00cal/g·°C, calculate the quantity of energy involved in the reaction.
