Question

64.8 g NOH_4 Express your answer using three significant figures. 4.64 kg N_2H_4 Express your answer using three significant figures. Consider the following balanced equation: 2N_2H_4(g) + N_2O_4g) rightarrow 3 N_2 (g) + 4 H_2O(g) Complete the following 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. Complete the first row. Express your answers using one significant figure separated by commas. Complete the second row. Express your answers as integers separated by commas. Complete the third row. Express your answers using two significant figures separated by commas.

Explanation / Answer

Question 1

I will assume that this is the decomposition reaction (since the info is not provided in the question)

3 N2H4 4 NH3 + N2

molar mass of N2H4 = 14 x 2 + 1 x 4 = 32 g/mol

C

mol of N2H4 = 64.8 / 32 = 2.025

mol of NH3 = 2.025 x 4 / 3 = 2.70

D

mol of N2H4 = (4.64 x 1000g) / 32 = 145

mol of NH3 = 145 x 4 / 3 = 193
