Carbon monoxide reacts with Oxygen to yield Carbon dioxide
how do i write that in skeleton formula

2CO + O2 -> 2CO2

Explanation:

In a 1.00 L flask, 2.4 atm of CO reacts with 4.5 atm of O2. Assuming that the temperature remains constant, what is the final pressure in the flask?

  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-
