Question 3 Consider the oxidation of dibarone below at 293K and calculate the AS for the universe
B2H6(g) + 302(g) - B2O3(s) + 3H20(1)
B2H6(8)
02(8)
B203(5)
H2001)
so
0.284J/mol*K
0.245 J/mol*K
0.031 J/mol*K
0.084 J/mol*K
AHformation
47.4 kJ/mol
O kJ/mol
-1,201 kJ/mol
-229 kJ/mol
Express your answer to 3 significant figures

PLEASE SHOW WORK (:

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
