Answer:
Polarity results from an unequal sharing of valence electrons. In SO3 there is the sharing is equal. Therefore SO3 is a nonpolar molecule.
Explanation:
Let the total mass of compound is 100g
The mass of each element will be
Al = 22.10 g
P = 25.40 g
O = 52.50 g
In order to determine the molecular formula we will calculate the molar ratio of the given elements
Atomic weight of Al : 27 g/ mol
Atomic weight of P : 3 1g /mol
Atomic weight of O : 16 g /mol
Moles of Al = mass / atomic mass = 22.10 / 27 = 0.819
Moles of P = mass / atomic mass = 25.40/ 31 = 0.819
Moles of O = mass / atomic mass = 52.50/ 16 = 3.28
Now we will divide the moles of each element with the lowest moles obtained to obtain a whole number ratio of moles of each element present
moles of Al = 0.819 / 0.819 = 1
moles of P = 0.819 / 0.819 = 1
moles of O = 3.28 / 0.819 = 4
So the empirical formula will be : AlPO4
Answer:
232 g CO2
2 C8H18 + 25 O2 --> 16 CO2 + 18 H2O
75.3 g C8H18 (1mol / 114.26g) (16 mol CO2/2 mol C8H18) (44.01 g/1 mol) = 232 g
Hope this helps!
Co2 and Fe are the products the other two are reactants.
