Examine the equation. 2ca + o2 → 2cao what is the best classification for the equation's reaction? single displacement decomposition synthesis double displacement

the answer is synthesis

Option (c) is the correct answer.

Explanation:

A synthesis reaction is defined as a reaction in which two substances or atoms combine together to result in the formation of a compound.

For example,

Here, calcium and oxygen combine together to form compound calcium oxide.

Whereas in a decomposition reaction, a compound decomposes into two atoms.

A single displacement reaction is a reaction in which one element is displaced by another element.

For example,

A double displacement reaction is a reaction in which elements of two compounds interchange with each other forming two new compounds.

For example,

Hence, we can conclude that given reaction is a synthesis reaction.

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.
