11. Calculate the molarity of a solution made by dissolving 23.4 g of sodium sulfate (Na 2 SO 4) in enough water to form 125 mL of solution. 12. Calculate the molarity of a solution made by dissolving 5.00 g of glucose (CNi (NO 3) 2 + 2NaOH → Ni (OH) 2 + 2NaNO 3. [ Check the balance ] Nickel (II) nitrate react with sodium hydroxide to produce nickel (II) hydroxide and sodium nitrate. Nickel (II) nitrate - diluted solution. Sodium hydroxide - concentrated solution.

The initial temperature of both solutions is 23.0°C. Assuming that the reaction goes to completion, and that the resulting solution has a mass of 100.00 g and a specific heat of 4.18 J/(g ∙ °C), calculate the final temperature of the solution. Ca2+(aq) + 2 F-(aq) → CaF2(s) ΔH° = -11.5 kJ . A) 22.45°C; B) 23.55°C; C) 24.10°C
what products result from mixing aqueous solutions Cu(C2H3O2)2(aq) and Rb3PO4(aq)? Chemistry. A 150.0 mL sample of a 1.50 M solution of CuSO4 is mixed with a 150.0 mL sample of 3.00 M KOH in a coffee cup calorimeter. The temperature of both solutions and the calorimeter was 25.2°C before mixing and 31.3°C after mixing.
BaCl 2 + K 2 SO 4 BaSO 4 + 2 KCl By examining the solubility rules we see that, while most sulfates are soluble, barium sulfate is not. Because it is insoluble in water we know that it is the precipitate. As all of the other substances are soluble in water we can rewrite the equation. BaCl 2 (aq) + K 2 SO 4 (aq) BaSO 4 (s) + 2 KCl(aq)
Aqueous solutions and Ionic equations Many substances dissolve in water to form aqueous solutions. Ionic substances are usually soluble, separating into their component ions: Al2(SO4)3 (s) 2 Al+3(aq) + 3 SO4-2(aq) The mobility of the ions in solution means that these solutions will conduct electricity (though the solid substance will not).
Salts Metal can be oxidized by aqueous solution of various salts. A + BX AX + B Displacement reaction occur if A is more easily oxidized than B. Example: Fe (s) + Ni(NO3)2 (aq) Fe(NO3)2 (aq) + Ni (s) 83 Cont: 4.4.2 Oxidation of Metals by Acids and Salts

What products result from mixing aqueous solutions of Ni (NO3)2 (aq) and NaOH (aq)? 5.Which of the following combinations will produce a precipitate? 1. AgNO 3 (aq) and HCl (aq) 2. MgCl 2 (aq) and Na 2 PO 4 (aq) 3.
6. Be aware of Disproportionation Redox Reactions. These are the reactions when a portion substance is oxidized while the rest is reduced. The same chemical substance undergoes both oxidation and reduction. NO 2 and H 2 O 2 are classic chemicals that have this ability. Example: 3NO 2 (g) + H 2 O 2H + (aq) + 2NO 3-(aq) + NO(g) 7.
