ECUACION QUIMICA BALANCEADA
El balanceo de ecuaciones químicas es una
operación matemática que se realiza para
mantener la ley de la conservación de
la materia en las reacciones. La materia no se
crea ni se destruye. Por lo tanto, el número de
átomos antes y después de una reacción
química debe ser el mismo, tanto en los
reactivos como en los productos.
Para balancear una ecuación química hay que
contar los átomos antes y después de la flecha.
Si los números coinciden, quiere decir que la
reacción está balanceada. De lo contrario, será
necesario igualar dichos números modificando
los coeficientes estequiométricos mediante
ensayo y error, siendo este el método más
simple e intuitivo para los balanceos. Cuando
se balancea por ensayo y error es como si se
quitaran o sumaran átomos en uno de los dos
lados del subibaja. Hasta que el subibaja no
esté suspendido en posición horizontal, la
ecuación química no estará balanceada por
completo. No puede haber más (crear materia)
ni menos átomos (destruir materia) en ninguno
de los lados.
