From the following data, calculate the average bond enthalpy for the NOH bond: NH3(g) ¡NH2(g) 1 H(g) ¢H° 5 435 kJ/mol NH2(g) ¡NH
Sphinxa [80]

Answer:

The average bond enthalpy for the N-H bond is 392 kJ/mol.

Explanation:

NH_3(g) \rightarrow NH_2(g) +1 H(g),\Delta H^o_{1}= 435 kJ/mol..[1]

NH_2(g) \rightarrow NH(g) + H(g),\Delta H^o_{2}= 381 kJ/mol..[2]

NH(g) \rightarrow N(g)+ 1 H(g),\Delta H^o_{3}= 360 kJ/mol..[3]

On adding [1] , [2] and [3] , we get:

NH_3(g) \rightarrow N(g) +3H(g),\Delta H^o_{4}= ?

\Delta H^o_{4}=\Delta H^o_{1}+\Delta H^o_{2}+\Delta H^o_{3}

= 435 kJ/mol+381 kJ/mol +360 kJ/mol = 1,176 kJ/mol

There three bonds N-H bond sin ammonia. Then average bond enthalpy of single N-H bond is :

\Delta H^o_{N-H}=\frac{1,176 kJ/mol}{3}=392 kJ/mol

The average bond enthalpy for the N-H bond is 392 kJ/mol.

MrRissso [65]

Answer:

A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

Solve for ‘x’: 12(x-7)+3(2x+2)=50x-2
Alex Ar [27]

Answer:

Explanation:

Hi there!

12(x-7) = 12x -84

3(2x+2) = 6x+6

Total 18x-78

18x-78 = 50x-2

-78= 32x-2

-76= 32x

19/8 =x

Hope you understand

Have a nice day,

Wolfiex.
