Write the chemical formula for the following compounds.ÂÂ
(i) Tin (IV) Oxide = ___________
(ii) Sulfur trioxide = ___________
(iii) Iron(II) Phosphate = ___________
(iv) Strontium Hydroxide = ____________
The correct answer and explanation is :
Chemical Formulas:
- Tin (IV) Oxide = SnO₂
- Sulfur Trioxide = SO₃
- Iron (II) Phosphate = Fe₃(PO₄)₂
- Strontium Hydroxide = Sr(OH)₂
Explanation:
(i) Tin (IV) Oxide (SnO₂)
Tin (IV) oxide consists of tin (Sn) with a +4 oxidation state and oxygen (O) with a -2 charge. Since oxygen has a charge of -2 and tin has a charge of +4, we need two oxygen atoms to balance one tin atom, leading to the formula SnO₂.
(ii) Sulfur Trioxide (SO₃)
Sulfur trioxide consists of one sulfur (S) atom and three oxygen (O) atoms. This is a molecular compound, and the name itself directly gives the formula: SO₃.
(iii) Iron (II) Phosphate (Fe₃(PO₄)₂)
Iron (II) phosphate contains Fe²⁺ ions and phosphate (PO₄³⁻) ions. To balance the charges, we need three Fe²⁺ ions (total charge = +6) and two PO₄³⁻ ions (total charge = -6). This results in the formula Fe₃(PO₄)₂.
(iv) Strontium Hydroxide (Sr(OH)₂)
Strontium (Sr) is an alkaline earth metal with a charge of +2. The hydroxide ion (OH⁻) has a charge of -1. To balance the charges, we need two hydroxide ions for every strontium ion, giving the formula Sr(OH)₂.
