Question

Consider the generic chemical equation below. X + Ymc021-1.jpg W + Z Reactant X contains 199.3 J of chemical energy. Reactant Y contains 272.3 J of chemical energy. Product W contains 41.9 J of chemical energy. If the reaction loses 111.6 J of chemical energy as it proceeds, how much chemical energy must product Z contain?

Answer 1

Its A 3181.1 j and now im just typing random stuff cause for some reason i cant answer the question without extra 

Answer 2

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:

$X+Y\rightarrow W+Z$

We are given,

$U_X=\text{Chemical energy of reactant X}=199.3J$

$U_Y=\text{Chemical energy of reactant Y}=272.3J$

$U_W=\text{Chemical energy of product W}=41.9J$

$U_Z=\text{Chemical energy of product Z}=?$

$\Delta U=\text{Change in Chemical energy}=111.6J$

$\Delta U=(U_X+U_Y)-(U_Z+U_W)$

Putting the values in above equation, we get

$111.6=199.3+272.3-U_Z-41.9$

Rearranging the terms, we get

$U_Z=318.1J$

Chemical energy product Z have is 318.1 J.
