Answer:
NH₄Cl ------> NH₃ + HCl
Explanation:
Ammonium Chloride =(NH₄Cl
Ammonia = NH₃
Hydrochloric Acid = HCl
NH₄Cl ------> NH₃ + HCl
In decomposition reaction, the reactant is breaking down into smaller parts. In this case, all of the coefficients are 1. The reaction is already balanced.
Let us see the structure of ascorbic acid
As shown there is no COOH group however the OH group can lose a proton and forms conjugate base
The conjugate base formed is stabilized due to resonance
More the stability of conjugate base more the strength of acid
Hence ascorbic acid behaves as an acid
Option d: copper.
Because copper is an element, not a mixture.
Melting, vaporization, boiling, and sublimation.
