CHM102 Lecture Notes - Lecture 9: Hydrogen Fluoride, Chemical Polarity, Heat Capacity
Premium

Intra and Intermolecular Forces Intermolecular forces are forces of attraction between molecules. Chemical changes are related to breaking and formation of intramolecular forces (i.e., covalent bonds). Physical changes ...

CHM102 Lecture Notes - Lecture 3: Chemical Formula, Atomic Mass, Molecular Mass
Premium

Percent composition Percent composition is the percentage of an element that is a particular mass. This is used to work out the atomic mass of an element. The atomic mass of an element is: Atomic mass = (mass of isotope...

CHM102 Lecture Notes - Lecture 2: Carbon-12, Significant Figures
Premium

Significant Figures Measured quantities are generally reported in such a way that only the last digit is uncertain. E.g. 4.0 g and 4.00 g imply different levels of uncertainty in the measurement. i.e. 4.0 0.1 g and 4.00 ...
