Can someone help meee PLEASEEE

contrast: unlike carbon dioxide and most of the substance, the phase diagram of water showed and negative slope for the boundary line between the liquid and solid state. this difference has to do with the fact that water activity expands as it goes from the liquid state to the solid state.

compare: carbon dioxide and water vapor temperature is very close to Unity, and then and the phase difference is basically out of the fees for the whole frequency ranges analyzed. The stampabilities are dependents for the normalized standard deviation of carbon dioxide is very similar to those of water vapor and temperature.

  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-
