<span>Many of the unique properties of metals can be explained by <span>metallic </span>bonds.</span><span>Metallic bonds can occur between different elements to form an alloy.</span><span>In contrast to electrons that participate in both ionic and covalent<span> bonds</span>, electrons that participate in metallic bonds delocalize, forming a sea of electrons around the positive nuclei of metals. The availability of "free" electrons contributes to metals being excellent conductors.</span>

You can solve this problem using ideal gas formula (PV=nRT). Remember that the temperature used is Kelvin, so 19.9°c would be: 19.9+ 273.15= 293.05<span>°K
PV=nRT
P= nRT / V
P</span>= 7.45 * 0.0821* 293.05 / 34.8
P= 5.15 atm = 3914.5 torr
1. Sulfur dioxide, or SO2 , has two resonance structures which contribute equally to the overall hybrid structure of the molecule. However, a third Lewis structure can be drawn for SO2 which is more stable in theory, but doesn't quite match experimental data.
