The graph represents the reaction 2H2 +02 = 2H20 as it reaches equilibrium. Based on the graph, which two statements about this reaction are true? A. At point 2, the concentrations of H20, 02, and H2 are all changing toward their equilibrium concentrations.

B. The rate of formation of products is equal to the rate of formation of reactants only after point 4.

C. After point 2, the rate of formation of products is equal to the rate of formation of reactants.

D. At point 1, more reactants are converted to products than products are converted to reactants.

lol idk man i guess u gotta ask bill nye the science guy

  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-
