Answer:
C. Larger compounds break down into two or more smaller compounds.
Explanation:
During a decomposition reaction, the bonds between the atoms break down in the starting substance. The atoms then rearrange to form new bonds, resulting in new substances with properties different from the starting material.
The United Nations Conventions on the Law of the Sea (UNCLOS) stipulates that seabed area, which is not within the landmark of any particular country should be regarded as a common natural heritage. Consequently, any mineral found in such an area can be used by anyone.
However, because of the abundant presence of sea area, and the way national boundaries often conflict, coupled with the problem of illegal mining practices, such laws are difficult to enforce, and so these regulations are not standardized yet.
Some possible impacts of ilegal seabed mining are:
1. Destabilisation of oceanic systems.
2. It constitutes danger to the organisms living in the hydrothermal vents.
San Francisco has an opportunity to reap tremendous economic, environmental, and health benefits by adopting recent advances in “green building”—benefits that will only increase in value over time. Many standard building design, construction, operation, and renovation practices are outmoded, inefficient, costly, and have adverse health and economic effects. The shift to new, environmentally sensitive practices would maintain San Francisco’s status as a leader in urban planning and environmental innovation. A shift to green buildings is also vital to enhancing San Francisco’s livability for its residents, workers, and visitors.
