UNIT 1: Lesson 2
As you read text pp 26-30, highlight, underline, write notes in the margin that will help you answer the
following questions over the content covered on these pages:
Properties are traits/characteristics describing a substance. So what’s a “chemical property?” Pg 26
Name 2 chemical properties that occur with oxygen, water and acid. Pg 26
What is a “chemical property” of iron [Fe]? …a physical property of iron? Pg 26 and Pg 25
What is a “chemical property” of silver [Ag]? …a physical property of silver? Pg 26 and Pg 25
Define the “chemical property” of flammability. Pg 27
Define the “chemical property” of reactivity. Pg 27
Why is nonflammable a “chemical property” if the substance does NOT burn and as a result does
NOT change into a new substance? Pg 27 & Pg 28
8. What is another name for an object that is nonflammable? Pg 27
9. What is a “characteristic property?” Pg 30
10. Name 4 “characteristic properties” of gold [Au] that distinguish it from iron pyrite [FeS2]. Pg 30

UNIT 1: Lesson 2
As you read text pp 26-30, highlight, underline, write notes in the margin that will help you answer the
following questions over the content covered on these pages:
1. Properties are traits/characteristics describing a substance. So what’s a “chemical property?”
Properties that describe a substance’s ability to change into a new substance with different
properties where its CHEMICAL IDENTITY CHANGED.
2. Name 2 chemical properties that occur with oxygen, water and acid. flammability and reactivity
3. What is a “chemical property” of iron [Fe]? …a physical property of iron? Chemical property =
rusting = new substance (iron oxide [Fe2O3]) …physical property = magnetism (most
magnetic element)
4. What is a “chemical property” of silver [Ag]? Tarnishing = new substance (tarnish) …physical
property = malleable; high luster
5. Define the “chemical property” of flammability. flammability = the ability to burn
6. Define the “chemical property” of reactivity. The ability of a substance to interact with
another substance and form new substance(s).
7. Why is nonflammable a “chemical property” if the substance does NOT burn and as a result does
NOT change into a new substance? ATTEMPTING to change a substance still results in a
chemical change even if not change occurs. (e.g. ATTEMPTING to burn gold)
8. What is another name for an object that is nonflammable? Flame resistant (fire retardant)
9. What is a “characteristic property?” unique physical and chemical properties that stay the
same regardless of the size of the sample and help identify a substance (also known as
intrinsic properties)
10. Name 4 “characteristic properties” of gold [Au] that distinguish it from iron pyrite [FeS2].
Malleability; streak test; luster; density
