c-c bond length in benzene is 1.397 angston and that of ethene is 1.34 angston structure of benzene is a resonance hybrid, therefore all the c-c bond lengths are equal but different from those in alkanes,alkenes, and alkynes.

What is the significance of the term compound in describing a modern light microscope?

Is sandy water an element or a compound or an homogeneous mixture or an heterogeneous mixture?
It is heterogeneous because the sand is not dissolved in the water. Apparently, the sand is still visible from the outside, unlike perhaps salt water in which the salt can no longer be seen.

Why can't subscripts be changed?
Because if you change a subscript, you change the compound. H2O is water. H2O2 is hydrogen peroxide. They are not the same thing. I assume you are balancing equations. Change the coefficients but then you are only changing the number of molecules of said compound and not the compound itsel.

Is aluminum chloride a metal?
Aluminum chloride is not a metal. When a metal (Aluminum) is compounded with a nonmetal (Chloride) the resulting compound is no longer a metal.It is an example of an inorganic compound that "cracks" at mild temperature, reversibly changing from a polymer to a monomer.
Is AR a compound?
No. If it is written Ar, it is the element Argon. If not, it may be the acronym for a longer-named compound, but it cannot be a chemical formula.
How do you test if a metal is a compound?
A metal cannot be a compound, or it would not be a metal. However, if a metal combines with something (e.g. iron combines with oxygen to form rust) it is no longer a metal (rust is not a metal - although it contains a metallic atom).You can, however, have a mixture of metals, e.g. pewter or solder or brass. But these are still metals, not compounds of them.
A longer word made of two shorter words is called a?

What is mercurechrome used for?
Merbromin (marketed as Mercurochrome, Merbromine, Sodium mercurescein, Asceptichrome, Supercrome and Cinfacromin) is an antiseptic used for minor cuts and scrapes.=It is no longer used because it contains mercury. Merbromin is an organomercuric disodium salt compound and a fluorescein.=
