A chemical reaction is one in which a substance undergoes changes in its chemical composition. These reactions are represented by chemical equations... Learn more about this topic: Writing Balanced Chemical Reactions from Chapter 2/ Lesson 14 24K...
If overly discharged, chemical reactions take place within the cell that permanently affect its ability to hold charge. Both cases involve the loss of battery cells in dangerous and expensive ways. Additionally, a BMS is needed since Li-Ion cells are often stacked to fo...
For chloride ingress, they are reactive transport models in which the diffusion of chloride ions is the main transport mechanism. Some models take into account the transport of other ions and/or water. The transport of chloride is coupled to a chemical model that describes the binding in the ...
Neutralization reactions are chemical reactions where an acid is neutralized by a base or vice versa. The products of the reaction are water and an ionic compound. The pH level of the neutralization solution depends on the stren...
Chemical reactions Now back to our battery. The positive and negative electrodes are separated by the chemical electrolyte. It can be a liquid, but in an ordinary battery it is more likely to be a dry powder. When you connect the battery to a lamp and switch on, chemical reactions start ...
Write the chemical equation for: Hydrogen carbonate + Nitric acid Write the balanced equation (not the mechanism) for the protonation of nitric acid by sulfuric acid, represented as an equilibrium expression. Nitric acid is a component of acid rain that forms when gaseous n...
The stepwise course of any given reaction mechanism can be represented using arrow pushing techniques in which curved arrows are used to track the movement of electrons as starting materials transition through intermediates to final products." [Organic chemistry. Wikipedia] The chemical symbols example ...
Enzymes are proteins in biological systems that help speed along reactions that would otherwise take place far more slowly than without the aid of the enzyme. As such, they are a kind of catalyst. Other, non-biological catalysts play a role in industry and elsewhere (for example, chemical cat...
These components, more generally known as electrodes, occupy most of the space in a battery and are the place where the chemical reactions occur. A separator creates a barrier between the cathode and anode, preventing the electrodes from touching while allowing electrical charge to flow freely ...
As with all elements, aluminum is a pure chemical substance that can't be broken down into something simpler. All elements are arranged in the periodic table by their atomic number -- the number of protons in their nucleus. Aluminum's lucky number is 13, so an aluminum atom has 13 ...
