The chemical formula for Zinc Sulfate is ZnSO4. Zinc Sulfate is also a polyatomic molecule, because the compound consists of more than three atoms (5). Zinc is a transitional metal and Sulfur is a nonmetal. Therefore, the two elements form an ionic compound.

For exanple, sodium hydroxide reacts with zinc and water to form sodium zincate and hydrogen gas. Zn(s)+2NaOH(aq)+2H2O(l)→Na2Zn(OH)4(aq)+H2(g).

As a result, the displacement reaction becomes vigorous and much faster with zinc dust. With the zinc powder, the reaction will proceed in a smooth and somewhat controlled manner. If the main purpose of the reaction is to prepare hydrogen gas, it is better to use granules of the metal than its powder.

In a solution H2SO4 splits in 2 H+ and a SO42- particle = 3 particles per mole. So 2 moles of H2SO4 will result in 3*2 = 6 moles of molecules (or, as in this case they are charged: ions).

Acids and Bases React with Metals Bases also react with certain metals like zinc or aluminum for example to produce hydrogen gas. For exanple, sodium hydroxide reacts with zinc and water to form sodium zincate and hydrogen gas. Zn(s)+2NaOH(aq)+2H2O(l)→Na2Zn(OH)4(aq)+H2(g).

Exploring the Activity Series Chart This shows magnesium is more reactive than zinc and both metals are more reactive than hydrogen. ... Adding a metal like copper to zinc ions will not displace the zinc since copper appears lower than zinc on the table.

Zinc Sulfide Formula. ... Formula and structure: The chemical formula of zinc sulfide is ZnS, and its molar mass is 97.47 g/mol. The chemical structure of ZnS is simple and consists of the zinc metal attached to a sulfur atom through a polar covalent bond.

Sulfur is called the oxidizing agent. The zinc causes the sulfur to gain electrons and become reduced and so the zinc is called the reducing agent. The oxidizing agent is a substance that causes oxidation by accepting electrons.

Zinc has the symbol Zn. Atomic Number = 30, Atomic Mass = 65.39, 30 protons, 30 electrons, 35 neutrons. Most common uses: The alloy brass contains copper and anywhere from 20-45% of zinc, depending upon the type of brass.

The standard answer is yes, because "H2SO4 is a strong acid, hence SO42− is a weak base. ... On its part, Cu2+ will strongly attract OH− groups, and overall protons will prevail over hydroxides."

Zno is an amphoteric oxide,because it can react with both acids and bases. while in general most oxides only react with acids alone due to its basic nature. Amphoretic oxides contradicts the Bronsted –Lowrey theory of acids and bases. Al2O3,SnO and ZnO are typical examples for amphoteric oxides.
