Observando la siguiente reacción química: 3Fe + 4H2O - Fe3O4 + H2(g) 4. Contesta ¿Por qué si se lleva a cabo en el recipiente abierto, la reacción no puede ir en la dirección inversa, pero
si la reacción se lleva a cabo en un recipiente cerrado, la reacción se convierte en reversible.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

here are some of the ways in which chemical and nuclear reactions differ.

explanation:

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
