If it is due to evaporation give with full proof and with the facts that should be clear to all of us. This results in the colours fanning out. They can be neutralised using baking powder which contains sodium hydrogen carbonate - a base.
Each wavelength bends by a certain amount, which causes the different coloured rays of light to exit the raindrop in slightly different directions.

People often favor one leg over the other. Put simply, an acid is any substance that has pH of less than 7. On adding small amount of base or acid to buffer, its pH hardly changes. This is a frequently asked question, though, because according to the general answer to the question of the sky's colour that because blue has a short wavelength it is caught and reflected in the sky , violet should be seen too, since its wavelength is even shorter than blue's. The energy of the Universe is constant; it can neither be created or destroyed but only transferred and transformed. Why Are There Only Seven Colours in a Rainbow?

Levorotation and Dextrorotation is referred to the properties of plane polarized light, when light rotates clockwise when it approaches the observer is then known as dextro-rotation and when the light rotates anti-clockwise then it is referred as levo-rotation. What is the Law of Conservation of Energy? Nickel is no longer used due to skin allergies. For this to happen, there must be rain, mist, or moisture in the air, and the moon must be reflecting the sun's light very brightly. This hub examines the answers to some of the top chemistry-related science questions I have been asked by my students in our science lessons. We use metals for many jobs in our technological world and sometimes a metallic element just won't cut it.
