LA LEY DE LA CONSERVACIÓN DE LA MASA ESTABLECE QUE, EN UNA
REACCIÓN QUÍMICA, LA MASA TOTAL DE LOS REACTIV

Ley de Conservación de la Masa

Imagínate que tienes un rompecabezas que desarmas y vuelves a armar de otra forma. Las piezas siguen siendo las mismas, solo cambian de lugar. Eso es exactamente lo que pasa en una reacción química.

La ley de conservación de la masa dice que cuando mezclas reactivos para crear productos, la masa total antes y después de la reacción es exactamente la misma. Los átomos no desaparecen mágicamente ni aparecen de la nada: solo se reorganizan para formar nuevas moléculas.

Piensa en el ejemplo del hidrógeno y oxígeno que se combinan para formar agua. Si pesas todo el hidrógeno y oxígeno antes de la reacción, y después pesas toda el agua que se formó, ¡la balanza marcará lo mismo! Los átomos simplemente cambiaron de vecinos, pero todos siguen ahí.

Tip clave: Esta ley te permite predecir cuánto producto vas a obtener en cualquier reacción química. Es como una receta de cocina: si sabes cuántos ingredientes tienes, puedes calcular cuánto pastel vas a hacer.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
