Answer:
Point source pollution:
If pollution comes from a fix source then is called point source pollution.It have a specific location where pollution comes.
Ex: Air pollution ,water pollution.
Non point source pollution:
If pollution comes from number of sources then is called point source pollution.This pollution does not have a specific point of source.
Ex: Spills ,leaks ,Sewage over flow etc.
The formula of Washing Soda is (Na2CO3.10H2O). It contains two atoms of Sodium,one atom of Carbon, thirteen atoms of Oxygen and twenty atoms of Hydrogen.
It's chemical name is Sodium Carbonate decahydrate. It is white coloured crystal which is basic in nature. So, it is called a basic salt. It turns red litmus paper into blue.
Answer the correct answer out of the four is option c spectroscopy
Explanation- The interaction between electromagnetic radiation and matter studied. This study is commonly known as spectroscopy. It can also be named as study of absorption spectra or emission spectra.
The former spectrum is formed when energy is absorbed from Photons or light energy by electrons while the latter spectrum is formed due to a wavelength of light that is released when electrons jump from higher to lower level.
Reduce the burning of fossil fuels by using electrical vehicles and instruments is the only solution to stop climate change.
<h3>
How climate change can be stopped?</h3>
Climate change is a process which occurs due to the release of greenhouse gases such as methane and carbondioxide gases. When fossil fuel is burn, it releases energy along with carbondioxide gas which blocks the escape of solar radiation.
This blockage leads to the warming of surface temperature. So if we switched to electrical vehicles instead of conventional vehicles, this climate change can be stopped.
So we can conclude that reduce the burning of fossil fuels by using electrical vehicles and instruments is the only solution to stop climate change.
