4PH3(g)→ P4 (g) + 6H2 (g) Suponga que, en un momento determinado durante la reacción, se está formando hidrógeno molecular con una rapidez de 0,078 mol/L s.
a) ¿A qué rapidez se está formando el P4?
b) ¿Con qué rapidez está reaccionando el PH3?

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
