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:
Explanation:
Pair 2.50g of O₂ and 2.50g of N₂
The atoms sample with the largest number of moles since the masses are the same would be the one with lowest molar mass according the the equation below:
Number of moles =
Atomic mass of O = 16g and N = 14g
Molar mass of O₂ = 16 x 2 = 32gmol⁻¹
Molar mass of N₂ = 14 x 2 = 28gmol⁻¹
Number of moles of O₂ = = 0.078mole
Number of moles of N₂ = = 0.089mole
We see that N₂ has the largest number of moles
