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,...
When zinc metal is added to a beaker of HCl(aq), a gas is produced. Knowing that zinc is oxidized and that hydrogen is reduced, write the balanced net equation for the reaction. (Use the lowest possible coefficients. Include states-of-matter under the given conditions in your answer.) What quantity of useful work can be obtained when Zn is added directly to the beaker of HCl? Please show work / equations thanks!
Step 1. Obtain
a 600 mL beaker, andadd 300 mL of water.
Step 2. Add 30 mL
of HCl (2M) to the beaker, and stir.
Step 3. Add 10 mg
of magnesium metal to the beaker.
Step 4. Allow
thehydrogen gas to evolve. All of the magnesium should be
consumed.
Step 5. Record
the amount of hydrogen gas that has evolved using the chemical
property dialog.
