Answer:
Mg₃N₂ (magnesium nitride)
Explanation:
M(total) = M(mg) + M (n)
M (n) = M(total) - M(mg)
= 0.433g - 0.313g
= 0.12g
mole (N) = 0.12g / 14.0067 g/mol
= 0.008567
mole Mg = 0.313g / 24.3050 g/mol
= 0.012878
Mg = 0.012878 / 0.008567
= 1.5
N = 0.008567 / 0.008567
= 1
multiply by 2 to get whole numbers
Mg = 1.5 × 2 = 3
N = 1 × 2 = 2
Mg₃N₂ (magnesium nitride)
Bronsted - Lowry acid in the given reaction is NH₄, as it gives H⁺ ion.
<h3>What is Bronsted - Lowry acid?</h3>
According to the theory of Bronsted - Lowry, acids are those substances which gives H⁺ ion or proton in the aqueous medium.
Given chemical reaction is :
NH₄ + HPO₄²⁻ → NH₃ + H₂PO₄⁻
In the above reaction NH₄ is the Bronsted - Lowry acid as it gives H⁺ ion in the reaction and changes to NH₃ which is the conjugate base of NH₄. Whereas HPO₄²⁻ is the Bronsted - Lowry base as it accepts the H⁺ ion to form H₂PO₄⁻ which is the conjugate acid of it.
Hence, option (1) is correct, i.e. NH₄ is the Bronsted - Lowry acid.

If you could explain what “merkels” are, the question would be more clear.
There are no options provided, therefor I cannot answer the question.
This is true
Because when water evaporates molecules break and separate into different atoms
