45. The reaction Cl2(g) 2Cl(g) is A. Exothermic because breaking bonds requires energy B. Exothermic because breaking bonds releases energy C. Endothermic because breaking bonds requires energy D. Endothermic because breaking bonds releases energy

C. Endothermic because breaking bonds require energy

Explanation:

The reaction as follows is given in this question:

Cl2(g) → 2Cl(g)

According to this equation, chlorine molecule (Cl2) is broken down into chlorine atoms (2Cl) by breaking the bonds that holds the two atoms in the molecule together. Breaking of chemical bonds require energy input to occur.

An endothermic reaction is a reaction in which energy is absorbed or used up rather than released. Based on this definition, the reaction involving the breaking of bonds in chlorine molecule is an ENDOTHERMIC REACTION because breaking bonds require energy.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

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.
