What is Sr2O7S2? Important knowledge about Sr2O7S2.

Firstly, I apologize, but it seems like your formula is incorrect. Sr₂O₇S₂ is not a valid chemical formula, perhaps there was a mix-up during your notation.

Consider the example of Strontium Sulfide (SrS) as a replacement for Sr₂O₇S₂ to carry out your tutorial.

1. Define SrS

1.1 Names
1.1.1 Common name: Strontium Sulfide
1.1.2 English name: Strontium Sulfide
1.2. Atomic mass: Strontium 38 and sulfur 16
1.3. Molar mass: 87.62 (Strontium) + 32 -> .06 (sulfur) = 119.68 g/mol
1.3.1 Molecular structure: A molecule of Strontium Sulfide comprises one atom of strontium and one atom of sulfur.
1.4 Ion structure: Strontium Sulfide has an ionic structure, where strontium transfers its two electrons to sulfur, forming Sr₂+ and S₂- ions.

2. Properties of SrS

2.1 Physical properties of SrS
State: Solid
Color: White or faint yellow
Odor: Odorless
PH level: Not applicable as it is insoluble in water
2.2 Chemical properties of SrS: Strontium Sulfide reacts with acid to form a strontium salt and hydrogen sulfide gas.

3. Common chemical reactions of SrS

• Reaction with sulfuric acid: SrS + H₂SO₄ -> SrSO₄ + H₂S

4. Synthesis of SrS

4.1 Laboratory synthesis of SrS: SrS can be synthesized by heating strontium and sulfur in an air-free environment.
4.2 Industrial synthesis of SrS: In industries, SrS is typically produced by reacting strontium carbonate (SrCO₃) with excess sulfur at high temperatures.
