Course: General Chemistry 2 Topic: Batteries and Fuel Cells • Re-explain the topic to the class as if you were teaching it to them in a way they can understand it. • You do not need ton of explanation, remember the minimum length of your explanation is 200 words. • Pick one to explain: 1st. Explain how primary batteries work. 2nd. Explain how secondary batteries work. 3rd. Explain how fuel cells work.
How the concentration polarization occurs in galvanic and electrolylic cells
11. What is the function of memory cells? how or when are they produced? 12. Explain how vaccination protects us based on what you know about primary and secondary/memory responses and memory cells. Include the terms primary response, secondary response and memory cells in your answer. 13. Do you agree or disagree with the following statement. The CD4T cell/Th cell is the commander in chief of our defence system. explain your answer. 14. We studied the immune system and innate...
Q1: a) Describe how a galvanic cell works and include a fully labelled sketch. Explain clearly what is occurring in each ‘side’. b) You add Mg to a beaker containing HCl(aq) and a gas is produced. Explain, chemically, what is happening and write a balanced equation for the reaction, including how many electrons are transferred. How could you harness the reaction to do useful work? c) The equation ΔGo = -nFEo is also applicable to half-reactions. Using standard reduction potentials,...
Please simulate and build a speech filter. The design should operate on less that ±6 Volts DC in Multisim. please show all works. Your circuit should address the following: Demonstrate the speech filter response of the design. Power analysis of the design What could you have done differently to make the circuit more efficient whether its cost, performance or simply a different design implementation? Project Requirements Create a project chair Research low power operational amplifier circuits. Assign task to team...
Please explain what you do and why.
A galvanic cell is setup with the following two half-cells: A 250.0 mL solution of 0.15 M aluminum nitrate with a platinum electrode. A 250.0 mL solution of 0.85 M cobalt(II) nitrate with a cobalt electrode. a) Determine the cell potential that will be initially measured for this galvanic cell b) How much mass is gained/lost by the cobalt electrode after the cell reaches equilibrium? c) If it takes this galvanic cell 2.00...
Show all steps please :)
A galvanic cell is prepared using the following two half-cells: (i) MnO4 (0.273 M), Mn2+ (0.167 M), and H+ (1.0 M), and (ii) Fe2+ (0.247 M) and Fe3+ (0.389 M). The standard reduction potentials for the two half cells are: Mnoa + 8H+ + 5e – Mn2+ + 4H20 E° = 1.507 V Fe3+ + e- Fe2+ E° = 0.770 V a) Calculate the voltage for this galvanic cell. b) Write the balanced equation for...
Explain the differences between prokaryotic and eukaryotic cells. Include a discussion on how cellular energy is created for the two different cell types.
Electrochemistry of Voltaic Cells: Batteries are voltaic cells. A typical AA battery is labeled as providing an electrical potential of 1.5 V. After a long period of time, a battery in use may no longer provide enough electrical power to the device. Suppose you have checked an old battery with a voltage probe and measured a potential of 0.9 V. What chemical change could be responsible for this change in voltage (and power)? Write one or two complete sentences to...
