Find n when 1 mol of each NH _ 3(g) and HCl _ (g) , reacts to form solid NH ₄ Cl .

Options

  1. A1
  2. B-2
  3. C-1
  4. D-3

Correct answer

B. -2

Step-by-step solution

The balanced chemical equation for the reaction is: NH _ 3(g) + HCl _ (g) NH ₄ Cl _ (s) The change in the number of moles of gaseous species, n , is given by the difference between the number of moles of gaseous products and gaseous reactants. Number of moles of gaseous products, n_P = 0 Number of moles of gaseous reactants, n_R = 1 + 1 = 2 n = n_P - n_R = 0 - 2 = -2 Answer: -2
