I believe the answer is Sorting, If not it is Filtration. If its neither of those, please give us options to pick from. If correct, please mark as branliest
In No3-1 the oxidation number of oxygen is -5 so oxidation number of N would be +5
Lewis structures are diagrams that show the bonding between
atoms of molecule and the lone pairs of electrons that may exist in the
molecule. Phosphoryl iodide is used in the preparation of organophosphorus
derivatives and phosphate esters. The Lewis structure of POI3 is:
Answer:
ΔSº= -41,2 J/molK
Explanation:
For a general equation aA +bB → cC + dD
ΔSº= c*SºC + d*SºD - a*SºA - b*SºB
ΔSº= SºAL2O3 + 2SºFe - SºFe2O3 - 2SºAl = (51 + 54.4 - 90 - 56.6)J/molK = -41,2 J/molK
