El carbonato de calcio, Cacos, se descompone a elevada temperatura en óxido de calcio, Cao, y dióxido de carbono, Co2
a) Escribe la ecuación química ajustada.
b) Calcula la masa de carbonato de calcio necesaria para
obtener 1000 kg de óxido de calcio.
c) Calcula el volumen de dióxido de carbono que se des-
prende en condiciones normales de presión y tempera-
tura, según el apartado anterior.

c is the answer because when something is left after something evaporates that shows the chemical change.

my dad did alot of meth and ace cheeks

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
