Question

By writing chemical equations explain how carbon dioxide reacts with
(a) water
(b) red hot coke
(c) magnesium​

Answer 1

Answer:

a)Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid. The cloudy white solution observed when CO2 is bubbled into limewater results from a reaction between Ca(OH)2 and either CO2 or H2CO3 to form an insoluble calcium carbonate precipitate.

b)When carbon dioxide reacts with red hot coke, carbon monoxide is formed. The balanced chemical equation for this reaction can be written as: Here, 1 mole of carbon dioxide reacts with 1 mole of coke to produce 2 moles of carbon monoxide. ... Thus, the final volume of gases will include the leftover CO2 and newly formed CO.
