Aluminum sulfide
In the compound H2S, hydrogen has an oxidation number of +1, and sulfur has an oxidation number of -2.
When zinc reacts with sulfur, they form zinc sulfide, a compound with the chemical formula ZnS. This reaction is a chemical change where the atoms of zinc and sulfur rearrange to form the new compound zinc sulfide.
When aluminum reacts with bromine, they form aluminum bromide, which is a white solid compound with the chemical formula AlBr3. This reaction is a redox reaction where aluminum loses electrons to bromine.
When iron reacts with sulfur, it forms iron sulfide. This is a chemical compound with the formula FeS. It is a grayish-black solid at room temperature.
The compound is Al2O3, which is aluminum oxide. This is formed when 4 moles of aluminum react with 3 moles of oxygen.
Aluminum Sulfide ==> Al2S3 Aluminum Sulfate ==> Al2(SO4)3 Aluminum sulfide is just aluminum and sulfur, while aluminum sulfate is Aluminum plus Sulfate (Polyatomic ion made of sulfur and oxygen)
Sodium sulphate.
Boron, silicon, germanium, arsenic, antimony, and tellurium are recognised. These elements include, hydrogen, beryllium, nitrogen, phosphorus, sulfur, zinc, gallium.
In the compound H2S, hydrogen has an oxidation number of +1, and sulfur has an oxidation number of -2.
When zinc reacts with sulfur, they form zinc sulfide, a compound with the chemical formula ZnS. This reaction is a chemical change where the atoms of zinc and sulfur rearrange to form the new compound zinc sulfide.
I think you are making a chemical mistake here. Let's see.2Al(OH)3 + 3H2SO4 --> Al2(SO4)3 + 6H2OThe reaction between aluminum hydroxide, a strong base, and sulfuric acid, a strong acid, produces a salt, aluminum sulfate [Al2(SO4)3 ] and water." sulfur hydroxide plus aluminum acid "Where you got these products I will never know!
iron sulphate
When aluminum reacts with bromine, they form aluminum bromide, which is a white solid compound with the chemical formula AlBr3. This reaction is a redox reaction where aluminum loses electrons to bromine.
Copper sulfide. Depending on the valence of copper, you could have CuS or Cu2S
When iron reacts with sulfur, it forms iron sulfide. This is a chemical compound with the formula FeS. It is a grayish-black solid at room temperature.
The compound is Al2O3, which is aluminum oxide. This is formed when 4 moles of aluminum react with 3 moles of oxygen.
In the compound Al₂O₃, aluminum has an oxidation number of +3, and oxygen has an oxidation number of -2. This gives a total charge of zero for the compound, as it should be electrically neutral.
