3.Se tiene media tonelada de Calcita (Carbonato de Calcio) que se descompone por acción del calor formando Óxido de Calcio y Óxido Carbónico. a. Escribir la ecuación de descomposición de la Calcita.

b. Calcular la masa formada de Óxido de Calcio.

c. Calcular el volumen de Dióxido de Carbono desprendido, suponiendo que se lo mide a 20º C y 1,4 atm de presión.

alguien me puede ayudar con esto por favor es un recuperatorio y la profe no había explicado esto porfisss lo suplico
​

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
