a Will dichromate ions oxidize chloride ions to free chlorine in acidic solution? Assume that the reaction occurs at standard electrochemical conditions. Half-Reaction & ° (V) Cr2O72- + 14H+ +66 +2Cr3+ + 7H20 +1.33 Cl2 + 2e → 201 +1.36 Yes No b Will Sn4+ oxidize NO2 to NO3. in basic solution? Assume that the reaction occurs at standard electrochemical conditions. Half-Reaction E ° (V) Sn4+ + 2e + Sna+ +0.15 NO3- + H2O + 2e → NO2+ + 2OH-...
Please help?
I
know the solution will be acidic because Kb of acetate > Ka of
Al(H2O)6^3+, but I don't understand why you would even compare the
Kb with the Ka
3. When dissolved in water, will aluminum acetate produce an acidic, basic, or neutral solution? Explain. Ka for Al(H20)63+ = 1.4 x 10-5 Ka for HC2H302 = 1.8 x 10-5
25. A 16.42-mL volume of 0.1327 M KMnO solution is needed to oxidize 2500 mL of a FeSO: solution in an acidic medium. What is the concentration of the Feso solution in molarity? The net ionic equation is 5Fe2+ MnOr - BH - Mn + 5Fe + 4H2O [8 pts] 26. A common laboratory preparation of oxygen gas is the thermal decomposition of potassium chlorate (KCIO.). Assuming complete decomposition, calculate the number of grams of Oz gas that can be...
You charge a piece of aluminum foil (mass = 7.55 g) by touching it to a charged rod. The charged rod gives the aluminum foil a charge of 10
can
you please explain why the solutions say it is acidic/ basic? i
dont understand the explanation one sheet. thank you.
4) What is the [H3O+] for a solution with a [OH-] of 2.73 X 102 M? Is the solution acidic, basic or neutral? *kw is constant giv The solution is basic because (OH) of 2.72 X 102 M is greater than 1.00 X 10' M. Kw = [H3O+][OH-] = 1.00 x 10-14 [H30+] = TOH-1 [OH-] = 2.72 X...
Permanganate ion can oxidize sulfite to sulfate in basic solution as follows. 2 MnO4" (aq) + 3 SO32-(aq) + H2O 2 MnO2(s) + 3 SO42-(aq) + 2 OH-(aq) Determine the potential for the reaction at 298 K when the concentrations of the reactants and products are as follows: [MnO4-] = 0.150 M, [SOy2-1.0.281 M, [SO42-1.0.199 M, and [OH- Will the value of Erxn increase or decrease as the reaction proceeds? increase O decrease Explain

5) A 3.50 kg piece of lead and a 1.5 kg piece of aluminum are placed in contact. They are able to exchange energy as heat, and they can only exchange it with each other. The initial temperature of the lead is 48°C, and the initial temperature of the aluminum is 35°C. a) If it is possible, construct a single, closed Energy-Interaction diagram for the process of lead and aluminum coming to thermal equilibrium. Write an algebraic expression of energy...
I can calculate molarity.
But I don't know how to balance the acidic equation.
Explain just about Balancing please.
Thank you much!
3. The concentration of hydrogen peroxide, H2O2, in a solution is determined by titrating a 11.5 mL sample of the solution with permanganate ion, producing Mn2+ ion and oxygen gas. Balance the chemical equation for the redox reaction that occurs in acidic solution. H2O2 + MnO4 +H+ ► 02 + H2O + Mn2+ How will you able to...
Could you explain why too? Thank you.
