10 Incredible Chemical Reaction GIFs Explained

10 Incredible Chemical Reaction GIFs Explained
We encounter thousands of chemical reactions every day: plants use them in photosynthesis, metals rust over time, and combustion reactions provide us with heat and light, among thousands of other daily uses. Chemical reactions occur when reactants transform into new substances, called products, through creating and breaking bonds between atoms. Sometimes the process creates some pretty wild effects. 1) Disintegration (Mercury Reacts with Aluminum) Image credit: Theodore Gray via Youtube When aluminum rusts, it creates a protective oxide layer that prevents the aluminum atoms underneath from further rusting. 2) Pharaoh's Serpent (Mercury (II) Thiocyanate Reacts with Oxygen) Image credit: tenkowal via Youtube The reaction depicted above, nicknamed the "Pharoah's Serpent," actually use to be a common classroom demonstration. 3) Explosive Gummi Bear (Heated Potassium Chlorate Reacts with a Gummi Bear) Image credit: ebaum via ebaumsworld.com Image credit: DizzyCtube via Youtube

REACCIONES QUÍMICAS INORGANICAS Es la parte de la química que se ocupa del cálculo de las cantidades de sustancia que intervienen en una reacción química. Definición Proceso en el que cambia la naturaleza de una o varias sustancias (reactivos), transformándose en otras nuevas(productos). Esto supone un reordenamiento de los átomos, mediante la ruptura de unos enlaces y la formación de otrosnuevos.Una reacción química se representa mediante una ecuación química: En el primer miembro aparecen las fórmulas de lassustancias que reaccionan (reactivos), y en el segundo miembro aparecen las fórmulas de las sustancias que se forman(productos), separados por una flecha, si la reacción es irreversible o por dos (una para cada sentido), si la reacción esreversible. Además de las fórmulas de las sustancias, deben aparecer los denominados coeficientes estequiométricos, loscuales nos indican la proporción (moles) de las sustancias que intervienen en la reacción (ajuste). a) 2Na + Cl 2NaCl (irreversible)b) H O (reversible)c) 2H (g) + O

Tipos de Reacciones y Ecuaciones Químicas Las reacciones químicas, son proceso, en los que, algunas sustancias, se recombinan con otras, para formar, sustancias nuevas; es decir, diferentes a las que tenía al principio. Estas reacciones, se representan, a través de las ecuaciones químicas. Veamos un ejemplo, para explicarlo: se tiene el hidrógeno molecular, más, el oxígeno molecular, que reaccionan, para formar agua. En estas ecuaciones, del lado izquierdo, se anotan los reactivos, que son las sustancias que se recombinan, y del lado derecho, los productos, que son las sustancias nuevas (H2+O----˃ H2O). En química, el “+” significa “reacciona”, y la flecha, significa “produce”. Los principales tipos, de reacciones químicas son: *Reactivos de adición: Aquellos que tienen, dos o más reactivos, que se combinan para formar un producto, generalmente más complejo, que los reactivos anteriores. *Óxido-reducción: Los elementos, cambian su número de oxidación, y de esa forma, pierden o ganan electrones.

An Atlas of Cyberspaces This is an atlas of maps and graphic representations of the geographies of the new electronic territories of the Internet, the World-Wide Web and other emerging Cyberspaces. These maps of Cyberspaces - cybermaps - help us visualise and comprehend the new digital landscapes beyond our computer screen, in the wires of the global communications networks and vast online information resources. The cybermaps, like maps of the real-world, help us navigate the new information landscapes, as well being objects of aesthetic interest. They have been created by 'cyber-explorers' of many different disciplines, and from all corners of the world. Some of the maps you will see in the Atlas of Cyberspaces will appear familiar, using the cartographic conventions of real-world maps, however, many of the maps are much more abstract representations of electronic spaces, using new metrics and grids.
