its A 3181.1 j and now im just typing random stuff cause for some reason i cant answer the question without extra
Answer: Chemical energy, product Z have is 318.1 J.
Explanation: Chemical energy is the energy stored between the bond of the compound.
For a given chemical reaction:
[tex]X+Y\rightarrow W+Z[/tex]
We are given,
[tex]U_X=\text{Chemical energy of reactant X}=199.3J[/tex]
[tex]U_Y=\text{Chemical energy of reactant Y}=272.3J[/tex]
[tex]U_W=\text{Chemical energy of product W}=41.9J[/tex]
[tex]U_Z=\text{Chemical energy of product Z}=?[/tex]
[tex]\Delta U=\text{Change in Chemical energy}=111.6J[/tex]
[tex]\Delta U=(U_X+U_Y)-(U_Z+U_W)[/tex]
Putting the values in above equation, we get
[tex]111.6=199.3+272.3-U_Z-41.9[/tex]
Rearranging the terms, we get
[tex]U_Z=318.1J[/tex]
Chemical energy product Z have is 318.1 J.
