Question

Express Chapter 4 Exercise 4.74 mol SU Consider the balanced equation: 2 N2H4(9) + N204(9) + 3 N2(g) + 4H2O(9) Complete the table showing the appropriate number of moles of reactants and products. If the number of moles of a reactant is provided, fill in the required amount of the other reactant, as well as the moles of each product formed. If the number of moles of a product is provided, fill in the required amount of each reactant to make that amount of product, as well as the amount of the other product that is made mol N H, mol N, O, mol N, mol H2O 10.9

Answer 1

Consider a reaction , 2 N₂H₄ (g) + N₂O₄ (g) $\rightarrow$ 3 N ₂ (g) + 4 H₂O (g)

From reaction, we have 2 mol N₂H₄ $\equiv$ 1 mol N₂O₄$\equiv$ 3 mol N ₂ + 4 mol H₂O

i e reactants and products are present in the ratio 2 : 1 : 3: 4 .

By using above information we can fill the table.

mol N2H4	mol N2O4	mol N 2	mol H2O
2	1	3	4
16	8	24	32
5.0	2.5	7.5	10
4.5	2.25	6.75	9.0
7.2	3.6	10.8	14.4
7.26	3.63	10.9	14.52
