Honors Chemistry Notes
Unit 1
• Matter- Anything that has mass and volume and anything that has the property of inertia.
-Quantitative.
-Can be solid, liquid, gas.
• Inertia- Ability to resist changes in its motion.
-Change in motion could be terms of speed or distance.
-A car that moves after it has stopped.
• Mass- The amount of matter in an object.
-The balances that you use in laboratory measure mass, not weight.
-SI unit is kilogram (kg).
• Conservation of Mass- The law states that matter is neither created nor destroyed in an ordinary chemical reaction.
-The mass put into the reaction will be the same as the mass put out of the reaction.
-To gain or lose mass an object must gain or lose atoms.
• Weight is a measure of the force of gravitational attraction between two objects.
-The weight of a certain object can change as it moves closer or further away from the earth.
-Newtons.
-Weight on the moon is 1/6th of what an object weighs on earth.
• Mass and energy can be converted together in a nuclear reaction.
• A fundamental property of an object is its mass, the amount of matter in the object. An object's weight is a measure of the gravitational force acting on it.
• Volume- Is the amount of space that an object takes up.
-Can be measured using graduated cylinders, beakers, and flasks.
-Milliliters (ml) and cubic centimeters (cm3).
• Milliliters and cubic centimeters are equivalent units.
• There 1000 milliliter in a liter.
• Density- Is the amount of matter in a given unit of volume.
-Grams per cubic centimeter (g/cm3).
-Density = Mass/ Volume.
• Substance – Matter with a constant composition.
-NaCl, H2O, Ne, CO2, and O2.
-Elements are compounds.
• Elements - Elements are substances that are made up of only one type of atom.
-The symbols shown on the periodic table.
-113 known.
-Each element is made up of its own type of atom.
- Each element has its own unique atomic number.
• Compounds - Compounds are substances that
