Estas composiciones no varían de una muestra a otra. Las sustancias puras se pueden categorizar en dos grupos:elementos y compuestos, dependiendo de si su estructura se puede descomponer o no. Por ejemplo, el hidrógeno es un what is composition in chemistry.

Los compuestos, por el contrario, son sustancias que pueden dividirse en sus elementos constitutivos solo mediante procedimientos químicos. Las mezclas también pueden clasificarse en dos tipos:homogéneas y heterogéneas, dependiendo de qué tan uniformemente se mezclen las sustancias que las componen. Una mezcla homogénea presenta una composición uniforme y, a la vista, se ve igual por todas partes. A este tipo de mezcla a menudo se le conoce como disolución.

Por ejemplo, una cucharada de sal disuelta en agua resulta en una mezcla homogénea porque cada gota de la misma posee la misma composición. What is composition in chemistry forma similar, la limonada también es una mezcla homogénea. Tomemos como ejemplo la arena mezclada con limaduras de hierro. En cualquier caso, cualquier mezcla, sea homogénea o heterogénea, puede volver a dividirse en sus componentes puros a través de procedimientos físicos sin que cambie la naturaleza de los mismos.

Por ejemplo, la sal se puede sacar de la disolución del agua calentando la mezcla hasta what is composition in chemistry se seque. Una sustancia pura es una forma de materia que tiene una composición constante con propiedades uniformes. Por ejemplo, cualquier muestra de sacarosa tiene la misma composición y las mismas propiedades físicas, como punto de fusión, which one is better love or friendship y dulzura, independientemente de la fuente de la que sea aislada.

Los componentes de una mezcla conservan sus identidades distintas. Las sustancias puras pueden dividirse en dos clases: Elementos y compuestos. El hierro, la plata, el oro, el aluminio, el azufre, el oxígeno is the internet dangerous debate el cobre son elementos. What is composition in chemistry sustancias puras que pueden ser descompuestas por cambios químicos se llaman compuestos.

What is cause-related marketing illustrate with examples desglose puede producir elementos, otros compuestos, o ambos. El óxido de mercurio IIun what is composition in chemistry cristalino anaranjado, puede ser descompuesto por calor en los elementos mercurio y oxígeno.

Cuando se calienta en ausencia de aire, el compuesto sacarosa se descompone en el elemento carbono y el compuesto agua. El cloruro de plata I es un sólido blanco que puede ser descompuesto en sus elementos, plata y cloro, por absorción de luz. Las propiedades de los elementos combinados son diferentes de aquellas en el estado libre o no combinado. Una mezcla homogénea, también llamada solución, muestra una composición uniforme y aparece visualmente igual durante todo el proceso.

Otros ejemplos de mezclas homogéneas son el aire, el jarabe de arce, la gasolina y una solución de sal en agua. Una mezcla con una composición que varía de un punto a otro se denomina mezcla heterogénea. El aderezo italiano es un ejemplo de what is composition in chemistry mezcla heterogénea.

Cualquier mezcla, ya sea homogénea o heterogénea, puede separarse en componentes puros por medios físicos sin cambiar las identidades de los componentes.

Y, por supuesto, hay innumerables maneras de combinar elementos y compuestos para formar diferentes mezclas. Este texto es adaptado de Openstax, Química 2e, Sección 1.
