The first step Niven has to do
in his calculation is to Balanced the chemical equation. The answer is letter
A. The key in the balancing of chemical reaction is to make sure that you got
the exact chemical formula of the substance that is reacting and the yielded
product. After getting the formula, identify first the hardest element/atom to
be balanced such as Na, Zn, Cl, etc. Then proceed to the easier ones such as O,
H. Make sure to not the atoms present in the molecule of the substance.
The structural form of the element Ge closely resembles the structure of C (diamond).
Diamond is composed of a lattice structure in which atoms of carbon are held together in a face centered cubic lattice.
Germanium, an element in the same group as carbon also forms a face centered cubic lattice that is very similar to that of diamond.
Hence, the structural form of the element Ge closely resembles the structure of C (diamond).

Answer:
0.733 mol.
Explanation:
- From the balanced equation:
<em>2Fe₂O₃ + C → Fe + 3CO₂,</em>
It is clear that 1.0 moles of Fe₂O₃ react with 1.0 mole of C to produce 1.0 mole of Fe and 3.0 moles of CO₂.
- Since Fe₂O₃ is in excess, C will be the limiting reactant.
<u><em>Using cross multiplication:</em></u>
1.0 mole of C produces → 3.0 moles of CO₂, from the stichiometry.
??? mole of C produces → 2.2 moles of CO₂.
∴ The no. of moles of C needed to produce 2.2 moles of CO₂ = (1.0 mole of C) (2.2 mole of CO₂) / (3.0 mole of CO₂) = 0.733 mol.
