2B Notes

Reactions occur in order that atoms gain stability. For example , oxygen will react with carbon for the reason that product, carbon dioxide, has more chemical stability - in other words, every single atom shares its bad particals to give the various other atom(s) inside the molecule a great electron agreement of even more stability the one ahead of.

When atoms and elements speed up or slow down, this is a physical modify. When they alter state by liquid to solid or from gas to liquid, that is a physical change. When a substance is definitely dissolved by simply water or some other solvent, a new element has not really been shaped. The ions or elements can still revisit together to create the original substance. In most chemical reactions, two or more chemicals, called reactants, interact to develop different substances called goods. A reaction is following a fundamental law of nature (enthalpy-its the nature of circumstances to want to work with the smallest volume of energy feasible, so if a reaction can happen that makes more strength, it will. As well, entropy-its the size of things to end up being as messy as possible, like the breaking down or perhaps decomposing of material).

Reactions describe all of the changes between reactants (the initial substances that enter into the reaction) and products (the final chemicals that are present at the end from the reaction). Talking about interactions between chemical varieties, chemical reactions entail a rearrangement of the atoms[-> 0] in reactants to form products with new structures in such a way about conserve atoms. Chemical equations are notations that are used to concisely summarize and communicate regarding reactions. In a well-balanced chemical reaction all of the matter[-> 1] (i. at the., atoms or perhaps molecules) that enter into a chemical reaction must be accounted for in the products of a reaction. Accordingly, linked to the symbols for the reactants and products are numbers (stoichiometry coefficients) that signify the number of elements, formula...
