Certainly, let's analyze and solve step-by-step:
1. First Row:
[tex]\[ 4 \text{ mol N}_2\text{H}_4 \rightarrow 2 \text{ mol N}_2 + \text{H}_2\text{O} \][/tex]
2. Second Row:
[tex]\[ 5 \text{ mol N}_2\text{O}_4 \rightarrow (\text{products}) \][/tex]
3. Third Row: Mole Balancing
- Given: 18 mol of [tex]\(\text{H}_2\text{O}\)[/tex]
- From the third row, we know that the oxidation process results in 18 mol of [tex]\(\text{H}_2\text{O}\)[/tex], but this is related to both reactions (from [tex]\(\text{N}_2\text{H}_4\)[/tex] and [tex]\(\text{N}_2\text{O}_4\)[/tex]).
4. Fourth Row:
[tex]\[ 4.5 \text{ mol N}_2\text{H}_4 \rightarrow (\text{products}) \][/tex]
5. Fifth Row:
[tex]\[ 4.5 \text{ mol N}_2\text{O}_4 \rightarrow (\text{products}) \][/tex]
6. Sixth Row:
[tex]\[ (\text{unknown mol N}_2\text{H}_4) \rightarrow 11.8 \text{ mol N}_2 \][/tex]
Given the available data, particularly the final moles of [tex]\(\text{N}_2\)[/tex] produced, let's verify the ratios using stoichiometry:
- In the first reaction:
[tex]\(4 \text{ mol N}_2\text{H}_4 \rightarrow 2 \text{ mol N}_2 \Rightarrow 1 \text{ mol N}_2\text{H}_4 \rightarrow 0.5 \text{ mol N}_2\)[/tex]
Therefore, [tex]\(4.5 \text{ mol N}_2\text{H}_4\)[/tex] will give:
[tex]\[ 4.5 \text{ mol N}_2\text{H}_4 \times 0.5 = 2.25 \text{ mol N}_2 \][/tex]
Similarly, for the second reaction in stoichiometric situation, assume:
- [tex]\(4.5 \text{ mol N}_2\text{O}_4\)[/tex] gives ratio observed in row data contribution to [tex]\(\text{N}_2\)[/tex] production.
Now calculating mole from [tex]\(\text{N}_2\text{H}_4\)[/tex]:
[tex]\(\text{N}_2\text{O}_4\)[/tex] contribution determines remaining [tex]\(11.8 - 2.25 = (x)\)[/tex] mol [tex]\(\text{N}_2\)[/tex]:

- First Week:
[tex]\[ Initial weight - Pounds lost = 30 \text{ lbs} - 2 \text{ lbs} = 28 \text{ lbs} \][/tex]
- Second Week:
[tex]\[ Weight after first week - Pounds lost = 28 \text{ lbs} - 3 \text{ lbs} = 25 \text{ lbs} \][/tex]
- Third Week:
[tex]\[ Weight after second week + Pounds gained = 25 \text{ lbs} + 2 \text{ lbs} = 27 \text{ lbs} \][/tex]
So, the detailed resultant weight sequences respectively:
[tex]\[ \boxed{(28, 25, 27)} \][/tex]
