Is the color observed in the flame test the result of the metallic ion or the nitrate ion explain why?
Nitrate ions have no colour, while transition metal ions do. The colour in the transition metal is due to ligands (such as nitrate in this case) approaching the ion along the x, y and z axes. As the dx2-y2 and dz2 orbitals lie on these axes they will be repelled by the ligand (negative charges repel each other). The other orbitals (dxy dyz and dxz) do repel the ligand as well just to a much lesser extent. This creates an ligand field (difference of energy between the orbitals) Photons are then absorbed by the dxy dyz and dxz orbitals . The wavelength of photons absorbed will affect the colour of light seen, ie if green light is absorbed violet will be seen (in permanganate ions).
Colors of sodium hydroxide in phenolphthalein?
pink to fuchsia or colorless depending on the amount of sodiumhydroxide . Sodium hydroxide is colorless. The Phenophtalein gives the solution its colour

What is earthquake and thunder?
In short, earthquake is when the surface starts shaking ....Lightening is when sky lights up with either blue, orange, red, purple or yellow colour...and after few seconds of lightening,... we can hear thunder(loud sound)
Is the amount of heat raditation absorbed by a surface depends only on its colour?
No !
How much solar energy is absorbed and how much is reflected from the earth's surface?
At the earth's surface about 51% of incoming solar radiation is absorbed, and 4% is reflected back into space.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
Is there such thing as dark white?
The colour 'white' when all of the light is bounced of the surface on which the colour is mounted. If the colour is darkened then there will be some light being absorbed into the surface. This means that the colour is no longer 'white' more of a grey or possibly black. :)
Why does black absorb the most energy from the sun?
Firstly, black is not a colour - it is the absence of colour (white isn't a colour either - it is a mixture or combination of all 'colours'). We see colour when its particular wavelength is reflected of the surface of something. The wavelength(s) reflected depends on the composition of the surface. Back to black - so when we see 'black' it is because all wavelengths of light has been absorbed by that surface. Light is energy; all that energy being absorbed = heat.
What happens to the rays when white light strikes a coloured surface?
The waves whose frequencies belong to that colour are reflected while other frequencies are absorbed.
Why does the colour of something affect the amount of heat it gains?
Because the colour of something affect the amount of heat absorption by radiation. Black bodies absorb the most radiation while white bodies absorb the least radiation. (reflecting heat radiation)Answer 2:The color of an object depends on what color of light it reflects back. A red object absorbs all other colors and reflects red light to your eyes. White is all colors and black is no light. You've probably heard wearing black in the sun makes you very hot. This is because there is no light being reflected back, it's all absorbed. A white shirt is cooler because it reflects all light colors and absorbs much less. Now, what determines the color that is reflected is the atomic composition of the object. Different colors of light have different frequencies, and certain atoms and materials absorb only certain frequencies of electromagnetic radiation (light). So it's not really the color that determines the amount of heat absorbed, it is the composition of the material that determines both the colors of light that are absorbed and thus, how much energy is absorbed. The color is a secondary effect perceived by you, it really doesn't control the heat absorption, it's a result of the atomic structure of the material.
What happens when all colors are absorbed?
When all colours are absorbed in an object you will get the colour black
Why do stars change colours?
They don't actually change colour but the earth's atmosphere causes an apparent change of colour according to the time of day. And other factors like the amount of radiation emitting from the star itself.
Why is white not a colour?
Colours are made because rays of coloured light are absorbed into whatever object. With white, all coloured rays are reflected and none are absorbed. It's not a colour, it's actually the lack of any colour.
Does PVC absorb radiation?
Depends what colour it is.
What is the best colour for radiation absorption?
hi
What is the color of alpha radiation?
Alpha radiation does not have a colour. In order for something to have a colour, it must emit rays of visible light. Alpha radiation and light are two different things which have little to do with each other.
