Question

Given the following description of reversal reactions, write a balanced equation (simplest whole-number coefficients) and the equilibrium constant expression (K) for each?....A) Nitrogen gas reacts with solid sodium carbonate and solid carbon to produce carbon monoxide gas and solid sodium cyanide...B)Solid magnesium nirtide reacts with water vapor to form magnesium hydroxide solid and ammonia gas.....C) Ammonium ion in aqueous solution reacts with a strong base at 25?C, giving aqueous ammonia and water? (If possible include steps)

Explanation / Answer

a ) N2(g) + Na2CO3(s) + 4 C(s) ? 2 NaCN(s) + 3 CO(g) b) Mg3N2(s) + 6 H2O(l) ? 3 Mg(OH)2(s) + 2 NH3(g) 3 Mg + N2 ? Mg3N2 c)NH3+H20 = NH4+ +OH- CH3COO- + H20 = CH3Coo- + OH - NH4 +n H2O = NH3 + H30+
