Options

A. `^^_(m(NH_4OH))^@+^^_(m(NH_4Cl))^@-^^_(m(HCl))^@`
B. `^^_(m(NH_4Cl))^@+^^_(m(NaOH))^@-^^_(m(NaCl))^@`
C. `^^_(m(NH_4Cl))^@+^^_(m(NaCl))^@-^^_(m(NaOH))^@`
D. `^^_(m(NaOH))^@+^^_(m(NaCl))^@-^^_(m(NH_4Cl))^@`

Answer

D

Explanation

`^^_(m(NH_4Cl))^@=^^_(m(NH_4^+))^@+^^_(m(Cl^(-)))^@`
`^^_(m(NaOH))^@=^^_(m(Na^+))^@+^^_(m(OH^(-)))^@`
`^^_(m(NaCl))^@=^^_(m(Na^+))^@+^^_(m(Cl^(-)))^@`
