The decomposition of N I 3 to form N 2 and I 2 releases − 290.0 kJ of energy. The reaction can be represented as 2N I 3 (s)→ N 2
ella [17]

Answer:

The change in enthaply when 10.0 g of nitrogen triiodide decomposes is -3.67 kJ.

Explanation:

2NI_3 (s)\rightarrow N_2 (g)+3 I_2 (g), \Delta H_{rxn} =-290.0 kJ

Enthalpy of the reaction when 2 moles of nitrogen triiodide decomposed =\Delta H_{rxn}

\Delta H_{rxn} = -290.0 kJ

Enthalpy of the reaction when 1 moles of nitrogen triiodide decomposed :

\Delta H=\frac{\Delta H_{rxn}}{2}=\frac{-290.0 kJ}{2} =-145.0 kJ

Mass of nitrogen triiodide decomposed = 10.0 g

Moles of nitrogen triiodide = \frac{10.0 g}{395 g/mol}=0.02532 mol

Change in enthaply when 0.02532 moles of nitrogen triiodide decomposed:

\Delta H\times 0.02532=-145 kJ\times 0.02532=-3.67 kJ

Atoms or clusters of atoms that are covalently bonded to carbon and influence the behavior of organic compounds are known as
SVEN [57.7K]

Answer:

Functional groups

Explanation:

A functional group refers to an atom or cluster of atoms that are covalently bonded to carbon and influence the behavior of organic compounds.

There are several functional groups in organic chemistry that determine the properties of organic compounds.

For instance, in the compound CH3CH2CH2CH2OH, the functional group is the -OH group. The chemical and physical properties of this compound is largely determined by this functional group.

Why is the nitrogen group considered a mixed group?
just olya [345]

Explanation:

The nitrogen group is considered mixed because it is composed of elements of equally different classifications of metal, non-metal, and metalloids.  The group contains the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metals bismuth (Bi) and Moscovium (Mc).
