In the correct Lewis Structure for the methand (CH₄) molecule how many unshared electron pairs surrounds the
a. Wave power:
- How is used to generate electricity: Wave power is used to generate electricity by capturing the kinetic energy of ocean waves and converting it into electrical energy through the use of wave energy converters.
- Advantages: Wave power is a renewable energy source, it is abundant and predictable, and it has low greenhouse gas emissions.
- Disadvantages: The technology for harnessing wave power is still relatively expensive and underdeveloped, it can be disruptive to marine ecosystems, and it is location-dependent.

b. Tidal power:
- How is used to generate electricity: Tidal power is used to generate electricity by capturing the energy of the tides as they ebb and flow, typically through the use of tidal turbines or tidal barrages.
- Advantages: Tidal power is a predictable and reliable source of renewable energy, it has low carbon emissions, and it can provide a consistent supply of electricity.
- Disadvantages: The infrastructure for tidal power can be expensive to build and maintain, it can have impacts on local marine ecosystems, and it is location-specific.
