Secondary Voltaic Cells
Voltaic cells that can be recharged, original reactanats can be regenerated be reversing the direction of the current flow.
Bond Energy
The amount of energy necessary to break one mole of bonds of a given kind (in gas phase).The amount of energy necessary to break one mole of bonds in a substance, dissociating the sustance in the gaseous state into atoms of its elements in the gaseous state.
Sulfuric Acid
H2SO4: colorless, oily liquid, boiling point 330C. A 96 percent solution is used in the laboratory.
Fire Hazard: This is a very powerful, acidic oxidizer which can Ignite or even explode on contact with many materials, i.e. acetic acid ,acetone+ HNOs, alcohols, + H202, NH4OH, HCL, NaOH, and others.
Sulfuric acid has a wide range of uses and plays a part in the production of nearly all manufactured goods.
