1. Your parents go through McDonalds drive-thru and get you a Big Mac and Coke. You take the lid off your Coke because it is too full and you need to sip some of the Coke so
it won't spill. After doing so, you forget to put the lid on. Then, a car pulls out in front of
you and your mom yells, "Look out!" You hold your cup still so it won't spill. However,

explanation:

  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-
