0.07g of a gaseous hydrocarbon occupied a volume of 56centimeter cube at s. t.p. on analysis, the compound contains 14.29% hydrogen by mass. what is the molecular formular of the compound?

i think so it’s will be b yes i believe its

the dependant variable is spilled water

the independent is the heat

  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-
