Question

state the preparation of carbon di oxide and write its equation ​

Answer 1

when a carbon atom combine with 1 oxygen molecule , carbon dioxide forms.

equation - CO2

Answer 2

Answer:

Carbon-di-oxide can be prepared either in laboratory or in industries.

Explanation:

(i) In laboratory , it can be easily prepared by the action of dilute Hydrochloric acid (Hcl) on marble chips .

Equation :

$CO_3^2- (Aq) + 2H^+ (Aq) \implies CO_2 (g)+ H_2O (L)$

(ii) In industries it can be produced as a by-product during the manufacturing of quicklime and in fermentation processes :

$CaCo_3(s)\implies Cao(s)+ Co_2 (g)$
