What is the maximum mass of pure gold that could be extracted from 3.0kg of calaverite, a gold ore with the chemical formula AuT

Marina86 [1]

Answer:

1.3 × 10³ g

Explanation:

Step 1: Convert the mass of calaverite to grams

We will use the relationship 1 kg = 1,000 g.

$3.0kg \times \frac{1,000g}{1kg} = 3.0 \times 10^{3} g$

Step 2: Establish the appropriate mass ratio

The mass ratio of AuTe₂ to Au is 452.17:196.97.

Step 3: Calculate the maximum mass of pure gold that can be obtained from 3.0 × 10³ g of calaverite

$3.0 \times 10^{3} g Calaverite \times \frac{196.97gAu}{452.17gCalaverite} = 1.3 \times 10^{3} gAu$

Where does oxidation occur in an electrochemical cell?

AlladinOne [14]

Option No. 1 at the cathode in both an electrolytic cell and a voltaic cell

Negative ion arrives at the anode, attracted by electrostatic forces, where they lose electrons. Loss of electrons is defined as oxidation.

The reverse process occur at the negative electrode, where positive ions pick up electrons. They are reduced.
