Note for advanced students: you can assume the reaction is run under mild conditions.

Identify the first chemical step in the production of Portland cement. How is this reaction related to the chemistry that takes place in the carbonation of concrete?

Provided is a picture of my problem. I understand that According to Le Chatelier's principle when stress is applied on reaction at equilibrium then the reaction will shift towards those direction where the stress is released. I also understand that the answer for a. Is move right, b. Is move right, and c. Is shift left, but I still don’t understand the knowledge behind why stress is released on this sides in those particular situations. Please help by providing steps

d. Provide the overall balanced equation for this galvanic cell. e. Write the line notation for the cell. f. Calculate the standard cell potential.

In a Galvanic cell, a salt bridge is often used. Explain why this is necessary. Describe the movement of ions in the saltbridge.

To remove the tarnish (Ag2S) on a silver spoon the following steps are carried out. the spoon is placed in a large pan filled with water so the spoon was totally immersed. A few tablespoonfuls of baking soda (sodium bicarbonate), which readily dissolves. Is added. Some aluminum foil is placed at the bottom of the pan in contact with the spoon and then heated the solution to about 80° After a few minutes, the spoon is removed and rinsed with cold water. The tarnish is gone and the spoon regains its original shiny appearance. Describe with equations the electrochemical basis for the procedure. Adding NaCl instead of NaHCO3 would also work because both compounds arestrong electrolytes. What is the added advantage of using NaHCO3? (Hint: Consider the pH of the solution.) What is the purpose of heating the solution? Some commercial tarnish removers containing a fluid (or paste) that is a dilute HCl solution. Rubbing the spoon with the fluid will also remove the tarnish. Name two…

You know that an unlabeled bottle contains an aqueous solutionof one of the following: AgNO3, CaCl2, or Al21SO423. Afriend suggests that you test a portion of the solution withBa1NO322 and then with NaCl solutions. According to yourfriend’s logic, which of these chemical reactions could occur,thus helping you identify the solution in the bottle?(a) Barium sulfate could precipitate. (b) Silver chloridecould precipitate. (c) Silver sulfate could precipitate.(d) More than one, but not all, of the reactions described inanswers a–c could occur. (e) All three reactions described inanswers a–c could occur.
