In carbon dioxide (co2), there are two oxygen atoms for each carbon atom. each oxygen atom forms a double bond with carbon, so the molecule is formed by two double bonds.
two double bonds means that the total number of electrons being shared in the molecule is
a) two.
b)four.
c)six.
d)eight.

8 electrons are being shared in the molecule

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
