Question

analyzing data
proportional relationships in chemical reactions
a chemist runs three trials of an experiment to produce ammonia (nh₃) from nitrogen (n₂) and hydrogen (h₂). the unbalanced equation is
n₂ + h₂ → nh₃
the chemist places different amounts of the reactants in a reaction vessel, adjusts some of the conditions such as pressure and temperature, and then records the amounts of the reactants and the products in the table.

Explanation:

Trial 1: Calculate change in \( N_2 \)

The change in amount of \( N_2 \) is original amount minus final amount.
\( 0.345 - 0.335 = 0.010 \) mol

Trial 1: Calculate change in \( H_2 \)

Change in \( H_2 \) is original minus final.
\( 0.345 - 0.315 = 0.030 \) mol

Trial 1: Calculate change in \( NH_3 \)

Change in \( NH_3 \) is final minus original (original is 0).
\( 0.020 - 0.000 = 0.020 \) mol

Trial 2: Calculate change in \( N_2 \)

\( 0.102 - 0.032 = 0.070 \) mol

Trial 2: Calculate change in \( H_2 \)

\( 0.345 - 0.135 = 0.210 \) mol

Trial 2: Calculate change in \( NH_3 \)

\( 0.140 - 0.000 = 0.140 \) mol

Trial 3: Calculate change in \( N_2 \)

\( 0.345 - 0.305 = 0.040 \) mol

Trial 3: Calculate change in \( H_2 \)

\( 0.298 - 0.178 = 0.120 \) mol

Trial 3: Calculate change in \( NH_3 \)

\( 0.080 - 0.000 = 0.080 \) mol

Filling the table (rows as trials, columns as changes):

TrialChange in \( N_2 \) (mol)Change in \( H_2 \) (mol)Change in \( NH_3 \) (mol)
20.0700.2100.140
30.0400.1200.080

Answer:

The table with changes is as above. For each trial:

  • Trial 1: \( N_2 \): 0.010, \( H_2 \): 0.030, \( NH_3 \): 0.020
  • Trial 2: \( N_2 \): 0.070, \( H_2 \): 0.210, \( NH_3 \): 0.140
  • Trial 3: \( N_2 \): 0.040, \( H_2 \): 0.120, \( NH_3 \): 0.080
