Electrolysis is the process of applying an electrical current to a solution in order to separate the components of that liquid phase solution on the basis of their charge. If we consider molten calcium hydroxide, the ions present will be:
Ca⁺²
OH⁻
The cations, the ones with a positive charge, will be reduced at the cathode. Therefore, calcium metal will be produced at the cathode. The anions will be oxidized at the anode, which means hydrogen gas will be produced at the anode.
<span>Answer:
3 electron pairs
Let's take BF3 for an example.
When you find the valence electrons for this molecule --> [3+(3x6)], you'll get 24e-. You draw the Lewis dot structure and each of the F atom would have six dots around it (a total of 18 because there's 3 F atoms) and the B would have three lines [one line attached to each F. One line would equal to 2 valence electrons] and you get a total of 24 valence e-.
The question asks how many groups are on the CENTRAL atom, meaning on the B. It would be three</span>
