What is the hybridization state on the central N atom in the azide ion, N3−?

Chemistry
1 answer:
Sloan [31]3 years ago
4 0
The sp hybridization of the central nitrogen is consistent with the linear structure of the azide ion. In A, the terminal nitrogens may both be sp2 hybridized; after all the drawing looks similar to the double bond in ethylene.

How many molecules of ammonia are formed in the following equation: N2+3H2→2NH3
Katena32 [7]

Answer:

  • <u>two molecules of ammonia are formed by the reaction of one nitrogen and three hydrogen molecules.</u>

Explanation:

The  balanced chemical equation provides information on:

  • <u>Reactants</u>: those are the compounds that appear of the left side of the equation, each with its chemical formula.

  • <u>Products</u>: those are the compounds that appear on the right side of the equation, again, each with its chemical formula.

  • <u>Ratio</u>: the coefficients of each compound (the number to the left of the chemical formula) represent the ratio of the number of molecules that react and are formed.

In the given equation you have:

  • Equation: N₂ + 3H₂ → 2NH₃

  • The coefficients are 1 for nitrogen, 3 for hydrogen, and 2 for ammonia. Hence, 2 molecules of ammonia are formed by the reaction of 1 molecule of nitrogen and 3 molecules of hydrogen.

Which label belongs in the region marked X?
lubasha [3.4K]

Answer:

A) involves changes in temperature

Explanation:

The figure is missing, but I assume that the region marked X represents the region in common between Gay-Lussac's law and Charle's Law.

Gay-Lussac's law states that:

"For an ideal gas kept at constant volume, the pressure of the gas is directly proportional to its absolute temperature"

Mathematically, it can be written as

p\propto T

where p is the pressure of the gas and T its absolute temperature.

Charle's Law states that:

"For an ideal gas kept at constant pressure, the volume of the gas is directly proportional to its absolute temperature"

Mathematically, it can be written as

V\propto T

where V is the volume of the gas and T its absolute temperature.

By looking at the two descriptions of the law, we see immediately that the property that they have in common is

A) involves changes in temperature

Since the temperature is NOT kept constant in the two laws.
