Question

Balance the following chemical equation:

a.    AD₄ +   X₂ →   AX₂ +   D₂X

b. Use the balanced equation to calculate the grams of AX₂ (Molar mass = 50.01 g/mol) produced from the reaction of 8.40 grams of AD₄ (Molar mass = 22.09 g/mol) with an excess amount of X₂?

   AX₂ grams

Answer 1

a.    AD₄ +   X₂ →   AX₂ +   D₂X ... unbalanced

AD₄ +   X₂ →   AX₂ +  2D₂X ... balanced for D and A

AD₄ +   2X₂ →   AX₂ +  2D₂X ... balanced for D, A and X = balanced equation

Use stoichiometry of balanced equation and dimensional analysis to find answer to part (b):

b.) 8.40 g AD₄ x 1 mol AD₄/22.09 g x 1 mol AX₂/1 mol AD₄ x 50.01 g AX₂/mol AX2 = 19.0 g AX₂
