science

• Mass


  The amount of matter in an object
• Volume


  The space occupied by the matter
• Temperature


  The measure of the coldness or hotness of a material
• Pressure


  The force applied by the gas particles per unit area
• Boyle's Law


  The volume of a gas is inversely proportional to its pressure at constant temperature
• Charle's Law


  The volume of a gas is directly proportional to its temperature at constant pressure
• Kelvin


  Unit for absolute temperature
• Binary Compounds


  Chemical compounds comprising two distinct elements
• Binary Acids


  Compounds with hydrogen (H) and a nonmetal (NM)
• Polyatomic Ion


  A covalent bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero
• Chemical reaction is a process in which a substance is changed into one or more new substances. It is represented using chemical equation.
• Reactant


  Starting material, written on the left side of an equation
• Product


  Substance formed as a result of a chemical reaction, written on the right side of the equation
• The Law of Conservation of Mass states that matter can be neither created nor destroyed, hence every chemical reaction must be balanced.
• Atoms are made up of protons, neutrons, and electrons.
• A molecule is two or more atoms chemically bonded together.
• Chemical reactions involve changes in the arrangement of atoms within substances.
• An ion is an atom with either too many or too few electrons to have a neutral charge.
• Electrolytes are compounds that dissociate into positive and negative ions when they dissolve in water.
