If liquid water runs into an open space within a rock, like a crack, and the temperature drops to the freezing point of water, what could result? the rock will shrink from the condensing of the water the rock will split due to the expansion of the water chemical weathering could eventually break down the rock inclusion of water into the crystals of the rock

The rock would most likely split

The rock will split due to the expansion of the water

i got this right on an assignment

  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-
