Answer to Problem 5RAT

The correct option for the statement “Is the following transformation representative of a physical change or a chemical change?” is option (c).

Explanation of Solution

The transformations of matter are of two types. The types are physical change and chemical change.

The physical change includes the change of states of matter. A chemical change occurs when two or more substances combine to form new and different substances. The given representation is shown below.

Fig. (1)

It is shown in the figure that two molecules transform to form two new and different molecules. So, the transformation shown is a chemical change.

The transformation is a chemical change because the atoms in the molecules have changed their partners and so formed new molecules.

Conclusion:

Therefore, the correct option is option (c).
