Three structural isomers have the formula c5h12. Draw and name the isomers using iupac names.

Pentane CH3-CH2-CH2-CH2-CH3

2-methylbutane  (CH3)2-CH-CH2-CH3

2,2-dimethylpropane  (CH3)3-C-CH3

Explanation:

An Isomer of a compound are other compounds that have the same formula with the original compound but have different arrangements.

Pentane as 2 other isomers. The other isomers of pentane are 2-methylbutane and 2,2-di methylpropane

Pentane CH3-CH2-CH2-CH2-CH3

2-methylbutane  (CH3)2-CH-CH2-CH3

2,2-dimethylpropane  (CH3)3-C-CH3

thats a little if u want the answer just look it up on google thats what i do haha : )

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
