Honors Chemistry Chapter 1 and 2 Test

Mass The measure of the amount of matter in an object.
Matter Anything that has mass and take up space.
Atom The smallest piece of matter that has physical and chemical properties.
Element A pure substance that is made of only one type of atom.
Extensive Property Depends on the amount of matter present
Intensive Property Doesn't depend on the amount of matter present
Physical Change A change in substance that does not involve a change in the identity of the substance
Physical Property A characteristic that can be observed without changing the chemical identity.
Endothermic Energy being absorbed.
Solid Definite Shape and Definite Volume
Plasma High temperature physical state of matter in which atoms lose most of their electrons.
Chemical Property A substance ability to undergo changes that transform it into different substances.
Chemical Change A change in which one or more substances is converted into a different substance.
Group Vertical columns and similar reactivity.
Period Horizontal rows that do not have similar properties.
Metal Malleable, Ductile, Luster,Good Electric Conductors, & Good Heat Conductors
Nonmetal Most are gases at room temperature, solids are brittle, and poor conductor of heat and electricity.
Metalloid Between metals and nonmetals, have characteristics of metal and nonmetals, and solids at room temperature.
Liquid Definite Volume but an indefinite shape.
Gas No definite volume or shape.
Compound A substance made from two or more elements that are chemically bounded.
Ectothermic Energy being released.
Mixture A blend of two or more kinds of matter.
Homogenous Mixture Mixtures that are uniform in composition. Solutions.
Heterogenous Mixture Mixtures that are not uniform in composition.
Pure Substance Has a fixed composition and exactly the same properties.
Noble Gases Unreactive Elements and Gases at room temperature.
What is the Scientific Method? 1. Observing and Collecting Data 2. Formulating Hypothesis 3. Testing Hypothesis 4. Formulating Theories
Comparing Mass and Weight Mass is the measure of the amount of matter in an object. Weight is the gravitational pull.
Density Mass X Volume
kg/m3 or g/cm3 = ? g/mL
Conversion factors always equal what 1
In conversions the numerator is always equal to what? The denominator.
Accuracy is what? Hitting your target.
Precision How close the trials are to each other.
l o (observed) - a (accepted) l Absolute Error
Ea (Absolute Error) / A (accept) x 100 =? Percent Error or Relative Error
Sig Figs are ?? Significant Figures
Non zero intergers Always count
Leading Zeros Never Count
Captive Zeros Always count
Trailing Zeros Only count with a decimal point
Exact Numbers (Determined by Counting i.e. 5 Dogs) Are infinite
When multiplying and dividing sig figs Fewest sig figs
M x 10 ^ n Scientific Notation
Direct Porportions Two quantities are directly proportional to each other.
Inverse Porportions Two quantities are inversely proportional to each other if their product is constant.
