The Standard Enthalpy of Formation of NH₄Cl(s)is -315

question 109

Multiple Choice

The standard enthalpy of formation of NH₄Cl(s) is -315.4 kJ/mol.The equation that describes this △_fH° is:

• A)NH₄⁺(aq)+ Cl^-(aq)→ NH₄Cl(s)
• B)1/2 N₂(g)+ 2 H₂(g)+ 1/2 Cl₂(g)→ NH₄Cl(s)
• C)N₂(g)+ H₂(g)+ Cl₂(g)→ 2 NH₄Cl(s)
• D)1/2 N₂(g)+ 1/2 Cl₂(g)+ 1/2 H₂(g)→ NH₄Cl(s)
• E)N₂(g)+ Cl₂(g)+ 4 H₂(g)→ 2 NH₄Cl(s)
