Expert Solution

Interpretation Introduction

Interpretation: Whether combination of A and B to form C is physical or chemical change should be determined.

Concept introduction: Changes can be classified as physical and chemical changes. Physical changes are such changes that allow change of state of matter only but not formation of new substances. Reversal of such changes is possible by physical methods.

Chemical changes allow formation of new and different substances from original substances via chemical reactions. These cannot be reversed back to original state by any method.

Explanation of Solution

Substances that are present in A and B have completely different properties than those formed in C. So when A and B are mixed to form C, it refers to chemical change.

Does this represent a chemical or a physical change? (c) Under a third set of conditions, the sample depicted in C changes to that in D. Does this represent a chemical or a physical change? (d) After the change in part (c) has occurred, does the sample have different chemical properties? Physical properties?

Disung dishing chemical and physical change There ar sketches below. The first sketch shows a sample of Substance X. The three sketches underneath it show three different changes to the sample. You must decide whether each of these changes is possible. If a change is possible, you must also decide whether it is a physical change or a chemical change. Each sketch is drawn as if the sample were under a microscope so powerful that individual atoms could be seen. Also, you should assume that you can see the entire sample, and that the sample is in a sealed box, so that no matter can enter or leave. Sample of Substance X Change 1 Change 1 is: impossible O a physical change O a chemical change Change 2 Change 2 is: O impossible O a physical change. O a chemical change. Change 3 Change 3 is: O impossible O a physical change O a chemical change
