The half-cell is a chamber in the voltaic cell where one half-cell is the site of the oxidation reaction and the other half-cell

is the site of the reduction reaction. type the half-cell reaction that takes place at the anode for the chromium-silver voltaic cell. indicate the physical states of atoms and ions using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively. use (aq) for an aqueous solution. do not include phases for electrons.

Start by writing a simplified reaction sequence between the two elements. For this, we need some electric potential values, which you can find in a table. Adjust based on the source that you are given, because they will differ just a little.

For the reactions, using a reductions table:

Cr3+ + 3e- —> Cd0 E=-0.74
Ag+ + e- —> Ag0. E=0.8

Because Ag+ has a larger E value, the Ag+ will oxidize Cd0 in the following reaction:

3Ag+ + Cr0 —> 3Ag0 + Cd3+

(Notice that three Ag’s are used to work for the transfer of three electrons.)

At the anode, the item in solution is oxidized so that electrons are left behind. This means that the reaction occurring at the anode is the Chromium reaction, and it looks like this:

Cr0(s) —> Cr3+(aq) + 3e-

Question 4 (1 point)
Diano4ka-milaya [45]

In an endothermic reaction products are <u>HIGHER </u>than reactants in potential energy and <u>LESS </u>stable.

Explanation:

Energy is input into the reaction in an endothermic reaction. This means the products are of a higher energy level than the reactants. Therefore the reaction increases Gibb's free energy and reduces entropy. Remember in thermodynamic stability involves an increase in entropy and a decrease in Gibbs free energy. Therefore the products are less stable than the reactants. This is why endothermic reactions do not occur spontaneously like exothermic reactions.

Find the mass, in grams, of 5.00*10^23 molecules of F2
Westkost [7]

Answer:   31.55 g

Explanation:

- The mass number of Fluoride atom (F) = 18.99 g/mol, so mass number of         fluorine gas (F2) = 37.98 g/mol.

-  1 mole of (F2) [which has 37.98 g/mol] contains Avogadro’s number of molecules (6.02×10^23 molecules),

   so   1 mole of (F2) with 37.98 g/mol →  6.02×10^23 molecules.

- Using cross multiplication,  

                               37.98 g/mol of (F2)        →       6.02 ×10^23 molecules

                                                       ?              →        5.00 ×10^23 molecules

Hence the mass of 5.00×10^23 molecules of F2 = (37.98 × 5.00 × 10^23) / 6.02 ×10^23 = 31.55 g..
