The standard molar enthalpy of formation of NH3(g) is -45.9 kJ/mol. What is the enthalpy change if 9.51 g N2(g) and 1.96 g H2(g)
Vladimir [108]

Answer:

\Delta H=-29.7kJ

Explanation:

Hello!

In this case, since the undergoing chemical reaction is:

N_2+3H_2\rightarrow 2NH_3

We first need to identify the limiting reactant given the masses of nitrogen and hydrogen:

n_{NH_3}^{by\ H_2}=1.96gH_2*\frac{1molH_2}{2.02gH_2}*\frac{2molNH_3}{3molH_2}=0.647molNH_3\\\\  n_{NH_3}^{by\ N_2}=9.51gN_2*\frac{1molN_2}{28.02gN_2}*\frac{2molNH_3}{1molN_2}=0.679molNH_3

It means that only 0.647 moles of ammonia are yielded, so the resulting enthalpy change is:

\Delta H=0.647molNH_3*\frac{-45.9kJ}{1molNH_3}\\\\ \Delta H=-29.7kJ

Best regards!

Refer to the following table of Ksp values to answer the question below.
marin [14]

HgS will precipitate first when tiny amounts of sulfide ion are slowly added to the solution.

<h3>What is Ksp?</h3>

The solubility product constant, Ksp​, is the equilibrium constant for a solid substance dissolving in an aqueous solution. It represents the level at which a solute dissolves in solution.

If Solubility product is greater than the ionic product then no precipitate will form on adding more solute because unsaturated solution is formed.

If Solubility product is lower than the ionic product then excess solute will precipitate out because of the formation of super saturated solution.

Here, Ksp value of HgS is very low. Hence, HgS will precipitate first when tiny amounts of sulfide ion are slowly added to the solution.
