Research project if you copie from chatgtp or any ai will be reported  Throughout this unit, you have conducted a research project into an electrochemical object of your choice:  Dear tutorr I have picked  standard alkaline battery You are to demonstrate an understanding of the technologies and processes relating to electrochemistry and their implications to society and the environment. What types of questions did you have about the object you selected that relate to the overall curriculum expectation above? You have developed 2-3 questions and researched them. Your questions should have been broad in nature and not something that could be answered in one sentence. For example, a question like, "Does my object make electricity?" would have been too basic (the answer is "Yes!"). Instead, a question like, "Why can't rechargeable batteries last forever?" would have been something to be explored in more detail and would have been a more appropriate question. Now, develop an information…

In the picture below, the flamming test is performed. What exactly is done in the picture and the table, what do the numbers and graphs mean, please explain clearly? (What is 3L, What is 100c, etc.)

It says on the photo to list all the types of batteries that we're using at home. So I've put these five things and googled each voltage, which became my answer on the second/middle column. The minimum of batteries is three only that is why I've put 1 thing that uses lithium-ion battery, 1 thing that uses alkaline battery, and 3 things that uses dry cell. Now, what I can't understand is WHAT WOULD I PUT ON THE ELECTROCHEMICAL REACTION?? (what should I put/answer on the last column?) I can't understand!!!

2H+ (aq) + Sn(s) → H₂ (9) + Sn²+ (aq) 2H+ (aq) + 2e → H2 (9) Ere = 0.000 V Sn2+(aq) + 2e → Sn(s) Eve = -0.140 V red Hint: Carry at least 5 significant figures during intermediate calculations to avoid round off error when taking the antilogarithm. Equilibrium constant at 298 K: AGº for this reaction would be [ than zero.

Wishing to record the "membrane potential" of a cell, Jane takes two electrodes connected to a volt meter. She places the cell in a dish filled with saline and touches each of the two electrode tips against the plasma membrane on the extracellular side. Jane will record a voltage of ________.   -20 mV   -70 mV   +70 mV   +10 mV   0 mV

ELECTROCHEMISTRY: Copper was electroplated from a Cu,so4 solution onto an electrode with an active surface area of 6.94 cm2 Determine the thickness (mm) of the deposit if the current is kept constant at 4.84 A for 1.4541 hours. (density of Cu = 8.96 g/cm3, MW of Cu = 63.55g/mol). Input values only with 2 decimal places. Do not include the unit.

What should you do if you spilled a tiny amount of hydrochloric acid on your hand? Describe a possible danger than can occur if you put food, soda, coffee, pencil erasers, etc. in your mouth while conducting your chemistry experiments? What information is given on a Safety Data Sheet? List optimum clothing, shoes, jewelry, and hair arrangement for your chemistry labs. What is the date that your fire extinguisher was last examined? How old are the batteries in your smoke detector? List the contents from your first aid kit that you will use to treat a minor cut. List the contents from your first aid kit that you will use to treat a minor burn.

How many hours are required to plate a 0.01 mm thick layer of Cr on an object whose area is 200 cm2 if the current used on the chromic acid (Cr(VI)) solution is 1.00 A and the density of Cr is 7.1 g/cc? Note. cc means cubic centimeter (cm³). mass = density x volume. volume of a surface = surface area x surface thickness.
