To find out if a dye is a mixture or not, you can make use of the chromatography method of separation.
If the dye is a mixture, the different elements inside the mixture will be separated out during chromatography and they will form different bands on the cinematographic paper but if the dye is composed of only one element, only one band will be formed on the cinematographic paper.
There are three rock types in the rock cycle including: igneous, sedimentary, and metamorphic rock.
<u>Explanation:</u>
Any solid or combination of minerals which naturally occurs is understood as a rock. It is classified by the contained minerals, its chemical composition and the manner it is made.
<u>Igneous Rocks:</u> It is generated by magma or lava being refrigerated and solidified. The magma may be produced from partial melting of established rocks, either in the mantle or crust of a planet. The melting is usually caused by one or more of three methods: temperature rise, pressure decrease, or composition transition.
<u>Sedimentary Rocks:</u> These forms that are developed by aggregation or deposition of tiny particles and eventual cementation of mineral or organic substances on the surface of the Earth's ocean floor or other water bodies. Sedimentation is the general term for mechanisms that cause settlement of such particles.
<u>Metamorphic Rocks:</u> These occur from the alteration of different rock types in a technique called metamorphism, which implies change of shape. The initial rock or protolith is heated where temperatures between 150 to 200 ° C and a pressure level of 100 megapascals (1,000 bar) or more induces significant physical or chemical changes.
When the solutions are diluted in half:
So [ Ca+2] = 0.001/2 = 0.0005 M
[SO4-2]= 0.01/2 =0.005
when Q = [Ca2+][SO4-2]
so by substitution:
Q = 0.0005*0.005 = 2.5x10^-6
by comparing with Ksp value
So when Q < Ksp
∴ the answer is no precipitation will occur, as the solution is unsaturated.
Color Change.
Production of an odor.
Change of Temperature.
Evolution of a gas (formation of bubbles)
Precipitate (formation of a solid)
Hope this helps!:)
