Suppose u r given 2 solutions a and b,how will u identify,which one is element and compound?
Answer:
A compound is a substance made up of atoms representing more than one element, and these atoms are typically joined in molecules. The composition of a compound is always the same: for instance, water always contains molecules composed of two hydrogen atoms bonded to a single oxygen atom. It can be frozen or boiled, but the molecules themselves are unchanged, because freezing and boiling are merely physical processes. To transform one compound into another, on the other hand, requires a chemical change or reaction.
An element is a substance made up of atoms with the same atomic number. Some common elements are oxygen, hydrogen, iron, copper, gold, silver, nitrogen, chlorine, and uranium. Approximately 75% of the elements are metals and the others are nonmetals. Most of the elements are solids at room temperature, two of them (mercury and bromine) are liquids, and the rest are gases.
A few of the elements are found in nature in the free (uncombined) state. Some of these are oxygen, nitrogen, the noble gases (helium, neon, argon, krypton, xenon, and radon), sulfur, copper, silver, and gold. Most of the elements in nature are combined with other elements in the form of compounds. The most abundant element on the Earth is oxygen; the next most abundant is silicon. The most abundant element in the universe is hydrogen and the next most abundant is helium.
are you studying in some school?
An element consists of only its own atoms while a compound consists of two or more element's atoms. For example, Hydrogen and Oxygen are elements while water (H2O) is a compound.
"A solution is a homogeneous mixture of one or more solutes dissolved in a solvent."
The definition itself says that it is a mixture.. so it can never be an element
Solution A<element> e.g: Mercury.
React it with any strong acid(HCl) and find the product formed.
Hg + HCl -> HgCl + H2
If a gas is evolved then it is an element.
Solution B<Compound> e.g: Mercury oxide.
React it with an excess of any strong acid and find the product formed.
HgO + HCl -> HgCl +H2O
If no gas is formed then it is a compound.
solutions means mixture of 2 or more components, so u can't have an element alone in a solution
there is something wrong.....
solution is neither a compound nor an element....
its a matter which comes under homogeneous mixtures which can be of comp 's or elements etc.........
