Answer:
Explanation:
The atom X has 1 1 protons (atomic number) and thus would have 11 electrons. This means the atom X would have 1 valence electron in it's outermost shell. While the atom Y has 17 protons (atomic number) and thus would have 17 electrons. This means the atom Y would have 7 electrons in it's outermost shell.
The type of bond this atoms (X and Y) would form is an Ionic (or electrovalent) bond. <u>This bond/combination involves the transfer of electron(s) and a molecule is not formed</u> as seen in the image below.
a.NH₃+HCl⇒NH₄Cl
b.volume HCl=150 ml
c. pH=4.82
<h3>Further explanation</h3>Reaction
NH₃+HCl⇒NH₄Cl
The equivalence point⇒mol NH₃=HCl
Titration formula :
M₁V₁n₁=M₂V₂n₂(n=acid base valence, NH₃=HCl=1)
mol NH₃
mol HCl=75 mlmol
Volume total :
mol NH₄Cl=mol NH₃=75 mlmol=0.075 mol
Dissociation of NH₄Cl at water to find [H₃O⁺]
ICE at equilibrium :
0.41-x x x
Ka(Kw:Kb)= 10⁻¹⁴ : 1.8.10⁻⁵=5.6.10⁻¹⁰
[H₃O⁺]=x :
pH=-log[H₃O⁺]
