There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide:

cac2(s)+2h2o(g)→c2h2(g)+caoh2(s)

in the second step, acetylene, carbon dioxide and water react to form acrylic acid:

6c2h2(g)+3co2(g)+4h2o(g)→5ch2chco2h (g)

write the net chemical equation for the production of acrylic acid from calcium carbide, water and carbon dioxide. be sure your equation is balanced.

The net chemical equation for the production of acrylic acid is given below.

Explanation:

We are given two intermediate equations:

Equation 1:  

Equation 2:  

To get the net chemical equation for the formation of acrylic acid from calcium carbide, carbon dioxide and water, we multiply the first equation by a factor of '6'.

The equation becomes:

Equation 1:  

Equation 2:  

Net chemical equation now becomes:

Hence, the net chemical equation for the production of acrylic acid is given above.

  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-
