Acombustion analysis of a 0.503 g sample of an unknown hydrocarbon yields 1.53 g co 2 2 and 0.756 g h 2 2 o. what is the empirical formula of the sample? give your answer in the form c#h# where the number following the element’s symbol corresponds to the subscript in the formula. (don’t include a 1 subscript explicitly). for example, the formula ch 2 2 o would be entered as ch2o

C₅H₁₂.

Explanation:

Which is corresponding to 0.03477 mol of C.

which corresponds to (0.042 x 2) = 0.084 moles of hydrogen.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
