? If a shortage of coal were to cause an increase in coal prices, how would it most likely affect renewable energy sources like solar energy? (A) The demand for renewable energy resources would increase. B The cost of land for renewable energy resources would decrease. © The need for renewable energy would remain constant as new coal locations are discovered. D The facilities for renewable energy would be built and used at night until all of the coal was depleted.​

  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-

my dad did alot of meth and ace cheeks

it's c (engineer's do their work with mechanical stuff not on any living being)

you need to stop taking that class
