An unknown gas x is said to be colourless, odourless, soluble in water and has a sharp refreshing taste
I. what is the name of the gas x
II. if the gas x is bubbled through lime water what observation can be seen
III. on continuous bubbling of the gas x through lime water the colour of solution disappears leaving a clear solution, give one chemical reason for the colour disappearance. and
IV. write a balanced chemical equation for gas x and lime water [(cacoh)2].

I. CO2

II. the lime water turns milky

III. an insoluble solution was formed; precipitation

IV. CO2+Ca(OH)2> CaCO3 + H2O

c.

explanation:

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
