H2SO4,.. Sulfuric Acid
- Sulfuric acid, H2SO4, is one of the most (or perhaps the most) significant compound or acid on the earth. It is colorles, odorless, and oily liquid. It composes of two hydrogen molecules, one sulfur molecule, and four oxygen molecules. Sixty-five percent of all fertilizer products in markets come from a mixture of sulfuric acid and other chemical substances. In fact, it is the most manufactured compound in the world; in the United States, more than forty million tons of the acid are produced annually.[1] Although sulfuric acid is one of the most significant substances in the world today, it was only a little known in the sixteenth century.
- Sulfuric Acid was discovered by a men named: Dutch-Flemist chemist, physiologist. In the early sixteen century.

Mercury(II) thiocyanate decomposition is initiated by heating (:
- To make mercury (II) thiocyanate aka mercury (II) rhodanide you will need water soluble mercury salt (I used mercury (II) nitrate) and ammonium thiocyanate (sodium thiocyanate also could be used). When these two solutions are mixed together mercury thiocyanate drops out. Filtrate it. Then wash it whith water. Dry it and use in your experiments. Нg(NO3)2 + 2NH4NCS = Нg(NCS)2 + 2NH4NO3 more info: www.faceofchemistry.com/
HCL + Aluminum foil = Fun (:
HCL + Aluminum foil = Fun
HCL + Aluminum foil = Fun
- The composition of aluminum foil is NOT 100% pure aluminum, as many people believe. You may have noticed that aluminum foil always seems dull on one side, and shiny on the other. This is caused by a naturally-occurring reaction. When Aluminum comes into contact with oxygen, the two elements undergo a spontaneous reaction:
4 Al(S) + 3 O2 (G) => 2 Al2O3 (S)
The aluminum foil reacts with oxygen in the air to form a thin layer of Aluminum Oxide on one side of the foil. Because rolls of aluminum foil are generally rolled tightly, the inner side of the aluminum foil is not exposed to the air as much, and it remains shiny.
In short, the composition of aluminum foil is pure aluminum (Al) AND aluminum oxide (AL2O3).
(And don't worry-- the layer of aluminum oxide on aluminum foil is completely harmless. We've been using foil to cover food for years, after all.)
