Problem 79

A compound with the empirical formula CH2 was found to have a molar mass of approximately 84 g. What is the molecular formula of the compound?

Step-by-Step Solution:
Step 1 of 3

For K(19) the nobel gas configuration is [Ar] s s and any other electrons that would come after the noble gas are valence electrons which are easily removed Effective nuclear charge, EA, and IE increase while atomic side decreases Effective nuclear Periodic table charge, IE, and EA decrease. Atomic size decrease Electron Affinity [EA] – energy change for the process of adding an electron to a neutral atom in the gaseous state to form a negative ion - Electron added = energy release EA is higher according to magnitude of the change of Energy Cl (-349) > I (-295.2) - Noble gasses have NO EA values - Often exothermic Chemical Bonds - Bonding occurs with valence electrons - Electrons are either valen
