For each of the following balanced reactions, calculate how many moles of each product would be produced by complete conversion of 0.50 mole of the reactant indicated in boldface. Indicate clearly the mole ratio used for the conversion. msp; 2 H 2 O ( l ) → 2 H 2 O ( l ) + O 2 ( g ) msp; 2 KClO 3 ( s ) → 2 KCl ( s ) + 3 O 2 ( g ) msp; 2 Al ( s ) + 6 HCl ( a q ) → 2 AlCl 3 ( a q ) + 3 H 2 ( g ) msp; C 3 H 8 ( g ) + 5 O 2 ( g ) → 3 CO 2 ( g ) + 4 H 2 O ( g )

Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds.
Thus, it is important to know which atoms carry unshared pairs.
Use the structural formulas below to determine the number of unshared pairs at each designated atom.
Be sure your answers are consistent with the formal charges on the formulas.
