Trapezoid abcd was dilated to create trapezoid a'b'c'd'. which statements are true about the trapezoids? check all that apply. the length of side ad is 8 units. the length of side a'd' is 4 units. the image is larger than the pre-image. sides cd and c'd' both have the same slope, 2. the scale factor is .

  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-
