When the electricity flows through the circuit they make, the electrolyte splits up and some of the metal atoms it contains are deposited in a thin layer on top of one of the electrodes—it becomes electroplated. All kinds of metals can be plated in this way, including gold, silver, tin...
For one, atoms are conserved (i.e. what goes in must come out), so we can immediately write the following relations (known as the element balance equations): The solution for the balance equations (listed above) are the following: And from this one can write the stoichiometric fuel-air ...
The negative terminal (red) is made of platinum, a precious metal catalyst designed to speed up the chemistry that happens in the fuel cell. When atoms of hydrogen gas reach the catalyst, they split up into hydrogen ions (protons) and electrons (small black blobs). In case you're confused...
Inside the panels are special materials called semiconductors. When the sun’s rays hit the solar panel, they transfer their energy to atoms in the semiconductor. This solar energy knocks electrons — tiny negative particles of energy — loose from the atoms, setting them in motion. As sunshine...
The chemical bonds between the atoms are shared pairs of electrons. Chemical bonds are much like springs: They can bend and stretch. These properties are important in detecting ethanol in a sample by infrared (IR) spectroscopy. Read More Types of Devices: Intoxilyzer Diagram of the Intoxi...

This causes hydrogen and oxygen atoms to be removed from the material by the dehydrating atmosphere and activation and carbonization to take place at the same time [2]. A rotary kiln is usually used as the reactor (Section 3.6). The pore structure and the pore volume are controlled via the...
