This is a simple displacement reaction - the more reactive magnesium displaces the less reactive copper from a solution of its salt. .... magnesium + copper sulphate ---> copper + magnesium sulphate Mg + CuSO4 ----> MgSO4 + Cu the blue colour of the copper sulphate will disappear and the silver coloured magnesium will be replaced by brown-red copper metal. Hope this helps. :)
Physicists do help people, even if it's not direct, e.g. without Physicists, there wouldn't be coloured TV, but even though Physicists didn't make the coloured TV, they're research on the three colours red green and blue was essential.
Granite is a felsic (composed of "light" coloured feldspars and silica minerals) intrusive rock. It is formed by the slow cooling and crystallisation of magma below the earths surface in a pluton or batholith. Basalt is the opposite of granite. Basalt is a mafic (dark coloured minerals rich in iron and magnesium)fine grained rock formed from the rapid cooling and crystallisation of lava above ground. Granite: Pale coloured, felsic, intrusive, coarse grained/porphyritic. Basalt: Dark coloured, mafic, extrusive, fine grained.
they r coloured due to electronic transitions in the constituent atoms....and photons are emitted which fall in the visible range..hence they appear coloured
The black "hot" conductor goes to the brass coloured screw. The white coloured conductor goes to the silver coloured screw. The bare ground conductor goes to the ground green coloured screw
Italy was the first country to experiment with colored fire works
It has the appearance of a thin silver-coloured ribbon.
Sodium, magnesium etc...

Blue and yellow make green. Experiment with the mix until you find the color you seek.
When we did it the other day what happened was this: the magnesium caused tiny bubbles and little dots of black fell to the bottom of the test tube (Copper I guess). When the reaction stopped, the liquid was still blue. We tried heating the mixture and got a bit more bubbles and 'dots' then we left the test tube for several days. Now the magnesium is coated with a pretty turquise coating of something, the solution is still blue, the dots are still black at the bottom of the tube. So CuSO4 + H2O + Mg should give you MgSO4 (which is soluble) and Cu. I do not know what we have actually got. The chemicals came from a chemistry set...the CaOH was equally not 'right' or rather it was far less 'basic' that I expected hmmm.
You could do a survey or ask people you know to choose a piece of food out of a group of different coloured foods
I'm pretty sure it is silvery (metallic white/grey) in appearance, but does burn at high temperatures. It burns a very bright white and is used in fireworks
It looks like Magnesium Iodide (and also its hexa- and octa-hydrates) is white or semi clear crystallic, solid salt.However, though magnesium iodide is stable at even high heat under a hydrogen gas atmosphere, it decomposes in air at normal temperatures, turning brown from the release of elemental iodine. When heated in air, it decomposes completely to magnesium oxide and (purple vapor of) iodine. This can be checkes with wet starchy test paper becoming black.
Softwoods can be coloured by staining.
why the things look to be coloured
light coloured
