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!

What kind of hydrocarbon is this? C-C-C-C-C-C-C-C-OH <br><br> Please help ASAP
Mice21 [21]

Answer:

1-Octanol

Explanation:

Count the amount of carbon atoms in the chain. Nomenclature includes the position of the largest functional group position in the molecule.

In this case the carbon chain has 8 carbon atoms and one hydroxide functional group (OH)  

1 (hydroxide is listed first in the carbon chain) - Oct(8 carbons) + anol (Alkanol hydrocarbon with a hydroxide group, use anol suffix )

=  1 - Octanol

A reaction has ∆H = −356 kJ and ∆S = −36 J/K. Calculate ∆G (kJ) at 25°C.
Cloud [144]

Answer: -345.2 KJ

Explanation: As we know that ,dG=dH-TdS

T=25+273=298 K

dG= -356 x1000-298(-36)= -356000+10728

=-345272 j

= -345.2 KJ
