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,...

Chem 1212 Lab Report on electrochemistry
Electrochemistry When electrons transfer between reaction components in a redox reaction, we can harness the motion of the electrons to create a potential. Electrochemistry revolves around the separation of the two half-reactions in a redox reaction and establishing two different electrodes. This might involve physically separating the half-reactions or including a separator, such as a semi-permeable membrane or plastic dividers. With the reactions separated, the electrons will need to flow through the wire connecting...

2. Using your trigonometry and algebra skills, show that the analytical solution for the critical distance is: Where hi, is the upper layer thickness and vi and v2 are the velocities of the two layers. Make sure to include a sketch of your setup and describe what you are doing. Please be neat and explain your steps. Hint: recall that the equation for the critical angle (ic) can be derived using Snell's Law Any student that can show that V21211/2...
