Problem 8

Table 6.1 lists some clues that a chemical reaction has occurred. However, these events do not necessarily prove the existence of a chemical change. Give an example for each of the clues that is not a chemical reaction but a physical change.

Step-by-Step Solution:
Step 1 of 3

Chemistry 111 Lecture Notes 2.3- Atomic number, mass number, and isotopes  Isotopes  Atoms of the same element but differ in the number of neutrons  Share similar chemical properties  Useful in decay measurements and isotopic labeling  Subatomic particles (most importantly protons) differentiates one atom of a particular element to that of another element.  Atomic number (Z)  Number of protons in nucleus of atom  All atoms of the same element have the same number of protons  Listed on periodic table EXAMPLE: Beryllium (Be) atomic number on the periodic table is 4 so it has 4 protons.  Mass number (A)  Number of protons + number neutrons in the nucleus  How to find number of neutrons  Mass number –at
