Que clase de ecuación química son:
a. be+so2 = beso4
b. cl2 + 2nabr = 2nacl + br2
c. beco3 + 2hcl = becl2 + h2co3
d. mg(no3)2 + koh = mg(oh)2 + kno3
e. cao + h2o = ca(oh)2
y porque? ?

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

The answer for this question is d. none of these

Ok so co(g) is not pronoused that. the only clue is that youpronouse it the oppisote way.
