Hey everyone. So we have the reaction of clark acid protesting hydroxide Whereas to provide the balance molecular and the ionic equations Support asked his h. c. l. 0. 3 and it's let me have the testing hydroxide which is K. O. H. Which is also a quiz. This is gonna be a double displacement reaction because we have two compounds reacting so we can switch the ions and form new products. So if you look at each reacting we have h. c. l. 0. 3 just going to associate into each plus C. L. 03 minus. Do you have K. O. H. Associating two K. Plus and O. H. Minus? So if you switch the ions we're gonna have a plus and O. H. Minus. It's gonna give us H. 20. Liquid which is water. Then we have K. Plus C. L. 03 minus. Could you give us K. C. L. 03 which is a quiz. The assault of group one elements are soluble and potassium is in group one. So our molecular equation it's gonna be a church c. l. 0. 3 inquiries plus K. O. H. A quiz. And it's gonna go K. C. L. 03. Hey chris Plus H. two L. Like what? And for the complete ionic equation we can write all the ions and leave any solid liquid or gas together and don't break them up. We're gonna have a plus C. L. 03 minus plus K. Plus plus O. H minus. It's gonna be okay Plus Plus c. l. 0. 3 Plus H. 20. The net ionic equation we can get rid of any spectator ions which exist as a reaction and a product. Okay. Plus Cielo 3 - are going to be our spectator Ion. So they're gonna cancel out for the Net Ionic equation. We're gonna have a church plus a quiz minus Aquarius. It's gonna your H. 20. Liquid. Thanks for watching my video and I hope it was helpful.

Textbook Question
The sodium–sulfur battery has molybdenum electrodes with anode and cathode compartments separated by b-alumina, a ceramic through which sodium ions can pass. Because the battery operates at temperatures above 300 °C, all the reactants and products are present in a molten solution. The cell voltage is about 2.0 V. (b) How many kilograms of sodium are consumed when a 25 kW sodium–sulfur battery produces current for 32 min?

Textbook Question
A concentration cell has the same half-reactions at the anode and cathode, but a voltage results from different concentrations in the two electrode compartments. (b) A similar cell has 0.10 M Cu2+ in both compartments. When a stoichiometric amount of ethylenediamine (NH2CH2CH2NH2) is added to one compartment, the measured cell potential is 0.179 V. Calculate the formation constant Kf for the complex ion Cu(NH2CH2CH2CH2)22+. Assume there is no volume change.

Textbook Question

Consider the redox titration (Section 4.13) of 120.0 mL of 0.100 M FeSO4 with 0.120 M K2Cr2O7 at 25 °C, assuming that the pH of the solution is maintained at 2.00 with a suitable buffer. The solution is in contact with a platinum electrode and constitutes one half-cell of an electrochemical cell. The other half-cell is a standard hydrogen electrode. The two half-cells are connected with a wire and a salt bridge, and the progress of the titration is monitored by measuring the cell potential with a voltmeter. (a) Write a balanced net ionic equation for the titration reaction, assuming that the products are Fe3+ and Cr3+.
