Honors Chemistry Notes
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.
-Each element is made up of its own type of atom.
- Each element has its own unique atomic number.
Compounds - Compounds are substances that are made up...
