Did you write these compounds? KBr 2 NH₂OH 2HNO3
1 answer:
The missing components of the neutralisation reaction include the following:
- KBr
- KBr 2NH4OH
- KBr 2NH4OH2HNO2
Neutralisation reaction is defined as the type of reaction that leads to the formation of salt and water when an acid and a base reacts.
From the reactions given the missing components are replaced as follows:
- HBr + KOH --> KBr + H2O
- H2SO4 + 2NH4OH --> (NH4)2SO4 + 2H2O
- 2HNO3 + Mg(OH)2 --> Mg(NO3)2 + 2H2O

Answer: Option (A) is the correct answer.
Explanation:
Atomic number of sodium is 11 and its electronic configuration is .
In order to gain stability, sodium loses one electron and hence it forms a positive ion .
Thus, we can conclude that when sodium combines with chlorine, it has a net charge of +1 because sodium loses a negative electron when forming chemical bonds.
