using Le Chanteliers principle what will happen and why when NaOH is introduced into iron(III) thicyanate ion equilibrium system

viktelen [127]

Answer:

More [FeSCN]²⁺ will be consumed shifting the reaction to the left.

Explanation:

Th equilibrium equation for iron(III) thiocyanate ion is:

Fe³⁺ + SCN⁻ ⇄ [FeSCN]²⁺

When NaOH is introduced into the equilibrium system, part of the OH⁻ ions react with the Fe³⁺ ions in solution, as per the chemical equation:

Fe³⁺ + 3OH⁻ ⇄ Fe(OH)₃ ↓ (solid precipitate)

Threfore, the concentration of Fe³⁺ ions in solution decreases.

How many grams of ammonia (NH3) will produce 300 grams of N2? 4NH3 + 6NO → 5N2 + 6H2O

jeka57 [31]

Molar mass

NH3 = 17 g/mol
N2 = 28 g/mol

4 NH3 + 6 NO = 5 N2 + 6 H2O

4 x 17 g NH3 ------------ 5 x 28 g N2
?? g NH3 --------------- 300 g N2

300 x 4 x 17 / 5 x 28 =

20400 / 140 => 145.71 g of NH3
