To study for a test, Ally created this table summarizing the characteristics of the six kingdoms: What should Ally put in X and Y?

X: mostly multicellular, nucleus, eat dead or decaying organisms
Y: multicellular, nucleus, consume food
X: unicellular, cell wall, no nucleus, moderate conditions
Y: mostly unicellular, nucleus, make or consume food
X: mostly unicellular, nucleus, make or consume food
Y: mostly multicellular, nucleus, eat dead or decaying organisms
X: unicellular, cell wall, no nucleus, extreme conditions
Y: multicellular, nucleus, consume food

  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-
