Calculate the cd^2+ concentration in the following cell if ecell = 0.23

cd | cd^2+ (x m) || ni^2+ (1.00 m) | ni

Explanation:

We must use the Nernst equation

Step 1. Calculate E°

Anode:     Cd ⟶ Cd²⁺(x mol·L⁻¹) + 2e⁻;                               E° =  +0.4030 V

Cathode: Ni²⁺ (1.00 mol·L⁻¹) + 2e⁻ ⟶ Ni;                            E° =  - 0.257    V

Overall:   Ni²⁺(1.00 mol·L⁻¹) + Cd ⟶ Ni + Cd²⁺ (x mol·L⁻¹);  E° =    0.146    V

Step 2. Calculate Q

3. Calculate [Cd²⁺]

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry
