Answer:
Ba²⁺(aq) + 2 Cl⁻(aq) + 2 NH₄⁺(aq) + SO₄²⁻(aq) ⇒ 2 NH₄⁺(aq) + 2 Cl⁻(aq) + BaSO₄(s)
Explanation:
Let's consider the molecular equation that occurs when aqueous BaCl₂ and aqueous (NH₄)₂SO₄ are mixed in solution to form aqueous NH₄Cl and solid BaSO₄. This is a double displacement reaction.
BaCl₂(aq) + (NH₄)₂SO₄(aq) ⇒ 2 NH₄Cl(aq) + BaSO₄(s)
The complete ionic equation includes all the ions and insoluble species.
Ba²⁺(aq) + 2 Cl⁻(aq) + 2 NH₄⁺(aq) + SO₄²⁻(aq) ⇒ 2 NH₄⁺(aq) + 2 Cl⁻(aq) + BaSO₄(s)
Answer:
25.41 g/mol is molar mass of metal.
Explanation:
Number of atom in BCC unit cell = Z = 2
Density of metal = 
Edge length of cubic unit cell= a
= ?
Radius of the atom of metal = r = 
Atomic mass of metal =M
Formula used :
where,
= density
Z = number of atom in unit cell
M = atomic mass
= Avogadro's number
a = edge length of unit cell
On substituting all the given values , we will get the value of 'a'.
25.41 g/mol is molar mass of metal.
