the following quantities are placed in a container:1.5x10^24 atoms of hydrogen, 1.0mol of sulfur, and 88.0 g of diatomic oxygen. a) what is the total mass in grams for the collection of all three elements? b) what is the total number of moles of atoms for the three elements? c) if the mixture of the three elements formed a compound with molecules that contain two hydrogen atoms, one sulfur atom, and four oxygen atoms, which substance is consumed first? d) how many atoms of each remaining element would remain unreacted in the change described in (c)?

  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-

lol for the pointsss

i wish i could but this one is weird give me abc and i can solve it.
