For the reaction: C4H10 + O2 = CO2 + H2O a.) what weight of C4H10 in grams is needed for 3.01 x 10^23 particles of O2?
b.) how many moles of CO2 will be produced from 5.0 moles of C4H10?
c.) what weight in grams of H2O will be produced from 12.5 mL of C4H10?
Density(p) of C4H10 = 0.506 g/mL

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.
