que no se supone que la ecuacion debe quedar equilibrada??

[dmorcillo]

@Metallica28051 Sí, ya, pero es un vídeo para mis alumnos. Que la equilibren ellos ¿no?

the chemical equation is not equal, and therefore BS. Cu + 4 HNO3 --> Cu(NO3)2 + 2 NO2 + 2 H2O this is true for 30-75% HNO3 3Cu + 8 HNO3 --> 3 Cu(NO3)2 + 2 NO + 4 H2O this is true for >75% HNO3

@Peterditaa Really? Thank you. I take note for next time.
