<span>Science involves Observation. With out observation then you do not have science. So, if you were studying plants for instance, you would be looking at the plants and drawing conclusions based upon your observations and experiments (and the observation of the experiments). Something that is not scientific is the theories of how this world came about. Neither the evolutionist view or the Creationist view is scientific, no one can observe what happened thousands of years ago. The theories of how this world came about are merely faith based. Atheist put their faith in billions of years and Christians to a higher power. So that would be an example of something that is not scientific.</span>
Answer:
Predominantly ,the color is due to cation Ba2+.
Explanation:
Flame Test : The flame due barium cation is Green in color.
Anions such as Cl- and SO42- slightly (very little) affects the color . Hence ,
BaCl2 and BaSO4 gives Yellow -green flame not pure green
Ba 2+ cation gives green colour because:
It has loosely bounded outermost electron (low ionisation)
It absorb energy from the flame , get excited to higher energy state. When the excited electron comes back to ground state , it emits colour of particular frequency.
Mizar is a quadruple or quaternary star system.
When there is more than two stars, it is called a star system or multiple star system or stellar system.
Depending on the number of stars, they are also called a triple, quadruple or quintuple star system or trinary, ternary, quaternary, quintenary, sextuple, sextenary, septuple or septenary star system.
