Have 10.0 M of CaCl₂ solution and want 3.00 L of .500 M, how much do you need to transfer? 3. AgNO₃ (aq) + KCl (aq) → ? is this a precipitate reaction? 4. Pb(NO₃)₂ (aq) + 2KI (aq) → ? is this a precipitate reaction? If so, what’s the net ionic equation? 5. HCl (aq) + H₂O (l) → ? which is the acid? Which is the base? 6. 20 mL of H₂SO₄ with unknown M, requires 22.87 mL of .158 M KOH to reach equivalence point, what is the value of the unknown M? 7. 2Na (s) + 2H₂O (l) → 2NaOH (aq) + H₂ (g) what is the oxidizing agent? 8. Temperature= 125° C, Pressure= 755 mmHg, what is the density of N₂? 9. CO (g) + 2H₂ (g) → CH₃OH (g) Have 35.7 g CH₃OH, what is the volume of H₂ at a temperature of 355 K and a pressure of 738 mmHg? 10.1.00 L of He, Ar, and Ne with total pressure equaling 662 mmHg, temperature of 298 K, pressure of He being 341 mmHg, and pressure of Ne being 112 mmHg, how many grams of Ar are there? 11.How fast is O₂ going at 25° C? 12.An unknown gas effuses at a rate that is 0.462 times that of N₂ at the same temperature, what is the molar mass of the unknown gas? 13.At 27° C, 130 atm, 1.50 L, and 10.0 mol, is this gas ideal? Midterm Review – Answers 1. Amount of solute (mol) / amount of solution (L) 2. A solid will be formed 3. Learn solubility rules!!! 4. The reactants that will form the solid 5. Acids are proton donors and bases are proton acceptors 6. Learn acid/base rules!!! 7. Moles of acid = moles of base to achieve neutralization 8. If a species loses electrons it is oxidized; if it gains electrons, it is reduced 9. The reducing agent is the chemical that was oxidized; the oxidizing agent was reduced 10.P₁V₁= P₂V₂ 11.V₁ / T₁ = V₂ / T₂ 12.V₁ / n₁ = V₂ / n₂ 13.PV = nRT 14.Standard temperature and pressure, with temperature being 0° C and pressure being 1 atm 15.n(total) (RT/V) 16.Pₐ = χₐP₊ 17.√3RT/MM 18.√MM(B) / MM(A) 19.[P + a(n/V)²][V – nb] = nRT 1. .122 M 2. 0.150 L 3. AgCl (s) + KNO₃ (aq) yes 4. PbI₂ (s) + 2KNO₃ (aq) yes Pb²⁺ (aq) + 2I⁻ (aq) → PbI₂ (s) 5. HCl is acid, H₂O is base 6. H₂SO₄ + 2KOH → 2H₂O + 2K⁺ + SO₄²⁻ molarity of H⁺ = .181 .181 M H⁺ ( 1 M H₂SO₄ / 2 M H⁺ ) = .0903 M 7. Oxidizing agent: H₂O (l) 8. (n/V) = .993 atm/ (.08206 L atm/ mol K)(398 K) = .0304 mol/L .0304 mol N₂/L (28.014 g N₂ / 1 mol N₂) = .852 g/L 9. 2.23 mol H₂ 2.23(.08206 L atm/ mol K)(355 K) / .971 atm = 66.9 L 10.P(Ar) = .275 atm .275 atm(1.00 L) / (.08206 L atm / mol K)(298 K) = . 0112 mol Ar .0112 mol Ar (39.95 g Ar / 1 mol Ar) = 0.449 g Ar 11.482 m/s 12.131 g/mol 13.P = 164 atm not ideal because pressures are different
