Answer:
The Earth's surface is constantly changing through forces in nature. The daily processes of precipitation, wind and land movement result in changes to landforms over a long period of time. Driving forces include erosion, volcanoes and earthquakes. People also contribute to changes in the appearance of land.
The longest hydrocarbon chain in the given compound is hexane, therefore it is the parent chain to be considered with one methyl group attached to the 3rd carbon and one chloro attached on the 2nd carbon, therefore the name of the compound is 2-chloro-3-methylhexane
Answer:
the wax is a nonpolar substance that will not mix with polar water
Explanation:
Water is polar by due to the uneven distribution of charge between the hydrogen and oxygen. T=This automatically eliminates options 3 and 4.
Wax on the other hand is a non polar substance. Due to this non polar characteristic, it would not dissolve in water. The correct option is;
- the wax is a nonpolar substance that will not mix with polar water
Answer : The disadvantage of using hydropower is Land can be flooded, displacing people and wildlife
Explanation :
Hydropower is a renewable source of energy. In hydropower, electricity is generated using the mechanical energy of moving water.
Since the kinetic energy is necessary to move the turbines, it is essential that the hydropower plant is present near a water source which has moving water.
It is the most efficient way of harnessing the energy from naturally available energy sources. It does not produce any waste. It does not pollute water or air.
Since hydropower needs kinetic energy of moving water, there is always a possibility of nearby land getting flooded. This would affect the people and wildlife of nearby areas.
Therefore the disadvantage of using hydropower is that land can be flooded, displacing people and wildlife
C) medium.
The medium of a wave is any substance that carries the wave, or through which the wave travels.Ocean waves are carried by water, sound waves are carried by air, and. the seismic waves of an earthquake are carried by rock and soil.
