Answer:
Empirical formula:
Fe₂O
Subscript of iron in empirical formula is 2.
Explanation:
Empirical formula:
It is the simplest formula that gives the smallest whole number ratio between the atoms of elements present in a compound.
Given data:
Mass of iron = 87.47 g
Mass of oxygen = 12.53 g
Empirical formula = ?
Solution:
Number of gram atoms of iron = 87.47 /55.845 =1.57 grams atoms
Number of gram atoms of oxygen = 12.53 / 16 = 0.78 grams atoms
Atomic ratio:
Fe : O
1.57/0.78 : 0.78/0.78
2 : 1
Fe : O = 2 : 1
Empirical formula:
Fe₂O
Subscript of iron in empirical formula is 2.
Answer:
Explanation:
A ) (NH₄)₃PO₄(aq) + Bi(NO₃)₃(aq) = BiPO₄(s) + 3 NH₄NO₃(aq).
B₁³⁺ + PO₄⁻³ = Bi ( PO₄ )
B ) AgOH(s) + H₂SO₄ (aq) = AgSO₄(s) + H₂O.
Ag⁺ + OH⁻ + H⁺ + 2 SO₄⁻² (aq) = Ag(SO₄)₂(s) + H₂O.
C ) HCIO₂ (aq) + Mn(OH)₂(s) = Mn(Cl0₂)₂ (aq) + H₂O.
H⁺ + OH⁻ = H₂O .
