The rule used here is that the algebraic sum of the oxidation numbers of all the atoms a molecule is zero.
Al2O32× ( oxidation number of Al)+3× ( Oxidation number of O ) = 0
2× ( Oxidation number of Al) +3(−2)=0
2× ( oxidation number of Al) +6
∴ Oxidation number of Al =+3
Refer to the diagram shown below.
The second axis is at the centroid of the rod.
The length of the rod is L = 100 cm = 1 m
The first axis is located at 20 cm = 0.2 m from the centroid.
Let m = the mass of the rod.
The moment of inertia about the centroid (the 2nd axis) is

According to the parallel axis theorem, the moment of inertia about the first axis is

The ratio of the moment of inertia through the 2nd axis (centroid) to that through the 1st axis is

Answer: 0.676
Well, i checked my cereal box and it says "net wait g (500)" so it's probably Grams
Answer = (C.) g
15mL because if it started as 20 mL and went to 35mL when u put in pyrite, the pyrite takes up 15mL
