What is a covalent bond? - Answer A covalent bond is a chemical bond that occurs when one or more electron is shared between the atoms. all intermolecular forces are much weaker than covalent bonds. True or False - Answer True. What are three types of intermolecular forces - Answer London dispersion, dipole-dipole, hydrogen bonding What are London dispersion forces? - Answer The intermolecular attractions resulting from the constant motion of electrons. What is a dipole-dipol...

significant figures a digit that is either reliably known or closely estimated Significant Figure Rules 1. All non-zero digits are always significant 2. Zeroes between non-zero digits are always significant 3. Zeroes to left of first non-zero digit (either before or after decimal point) are never significant 4. Zeroes to the right of last non-zero digit a. after decimal point are always significant b. which are before decimal point are not significant conversion factor relations...
