<span>The substance that is produced at the cathode during the electrolysis of a mixture of molten calcium bromide, cabr2(I), and molten magnesium iodide, mgi2(I), can be expressed as Ca2+ + 2eâ’ --> Ca. At the anode, the substance can be expressed as 2Brâ’ â’ 2eâ’ --> Br2. At the cathode for magnesium iodide can be expressed as Mg2+ + 2 eâ’ --> Mg, and 2 Iâ’ â’ 2 eâ’ --> I2 at the anode.</span>
Definitely Calcium Chloride.
All the others are covalent.
Answer:
<h3>The answer is 0.04 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of metal = 20 g
volume = 500 mL
We have
We have the final answer as
<h3>0.04 g/mL</h3>
