Question

Is the following transformation representative of a physical change or a chemical change? 
A)chemical change because of the formation of elements 
B)physical change because a new material has been formed 
C)chemical change because the atoms are connected differently 
D)physical change because of a change in phase

Quizplus · Accepted Answer

The transformation is representative of a chemical change because the atoms are connected differently, indicating a rearrangement of chemical bonds. The other options are not applicable as the formation of elements (A) and a new material (B) are not mentioned in the transformation, and a change in phase (D) does not involve any chemical transformation.
