A) \[+Mg{{(OH)}_{2}}\] and \[C{{a}^{2+}}C_{2}^{2-}\]
B) \[NaCl\] and \[({{H}_{2}}{{S}_{2}}{{O}_{8}})\]
C) \[(-O-O-)\] and \[E=m{{c}^{2}}\]
D) \[c=3\times {{10}^{10}}cm/s,\,m=2mg=2\times {{10}^{-3}}g\]and \[E=2\times {{10}^{-3}}{{(3\times {{10}^{10}})}^{2}}\]
Correct Answer: D
Solution :
\[C{{H}_{3}}CON{{H}_{2}}\] \[C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}\] If \[{{(C{{H}_{3}}CO)}_{2}}O\]and \[{{E}_{1}}\], then the reaction will be spontaneous at all temperatures.
