Identify the type of reaction: H2CO3 → H20 + CO2

In the reaction carbonic acid and decomposes form's a  water and carbon dioxide gas. Hence this is the an example of a decomposition reaction.

Explanation:

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
