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

You are a budding inventor who has just manufactured their own toy rocket from scratch. As your dream is to manufacture the most realistic toy ever, you wish to create even the rocket fuel. You don’t know how long you will need to store the fuel components for, so you will leave the Ammonium perchlorate in solution form until required. This ammonium perchlorate solution is made by combining 100 mL 1.2 mol Perchloric acid (HClO4) and 100 mL 2.0 mol of Ammonia (NH3). You need to know whether this solution is acidic or basic to ensure you store it safely and properly. What is the pH of the solution you created? Full solution please

Determine the equilibrium constant for the reaction Sn+Pb2+Sn2++Pb

5.11. Determine the numerical value of Q for the reaction conditions indicated.

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.

doug began preparing laboratory surface disinfectant from chlorine bleach. he put on a chemical resistant apron and gloves and then removed the bleach container from the special chemical cabinet. he carefully placed the container on the laboratory benchtop and began to add the chlorine bleach to distilled water. nearby workers began complaining of burning eyes. doug was reprimanded by the supervisor. Explain why.

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

Explain the meaning of “the reaction goes to less than 100% completion”
