A) \[-731kJ\]
B) \[-787kJ\]
C) \[-534\text{ }kJ\]
D) \[-554\text{ }kJ\]
Correct Answer: A
Solution :
\[\underset{-293}{\mathop{2Zn(s)}}\,+\underset{0}{\mathop{3{{O}_{2}}(g)}}\,\xrightarrow{{}}\underset{-480}{\mathop{2ZnO(s)}}\,+\underset{-544}{\mathop{2S{{O}_{2}}(g)}}\,\] \[\text{C}{{\text{H}}_{\text{3}}}\text{C}{{\text{H}}_{\text{2}}}\text{CON}{{\text{H}}_{\text{2}}}\] \[\text{C}{{\text{H}}_{\text{3}}}NCO\] \[\text{C}{{\text{H}}_{\text{3}}}\text{CON}{{\text{H}}_{2}}\] \[{{(N{{H}_{2}})}_{2}}CO\]You need to login to perform this action.
