Shown below is a lewis structure of the formamidinium ion. what geometry is exhibited by the two nitrogens in the formamidinium
ion?
2 answers:
If that is your picture, then the answer is that
Geometry A is trigonal planar
and Geometry B is trigonal pyramidal
Geometry A is trigonal planar
and Geometry B is trigonal pyramidal
The formamidinium ion structure is shown below.
Answer:
A: trigonal planar
B: trigonal pyramidal
Explanation:
In the formamidinium ion, there are two nitrogen atoms, which are represented below by A and B. The geometry of a molecule is determined by the VSEPR theory, which states that the bonded electrons and the lone pairs of electrons intended to repulse to form a more stable compound.
Nitrogen has 5 electrons in its valence shell, so n the nitrogen A, there are 3 bonds (1 double bond and 2 simple bonds), and there are no lone pairs in the nitrogen atom (the central atom), thus the repulsive forces will be only by the bonds, and the geometry will be trigonal planar.
In nitrogen B, there are 3 simple bonds and one lone pair, which contributes to the repulsive forces, thus, the geometry must be trigonal pyramidal.

The given question is incomplete. The complete question is :
Welding is an industrial process that is used to join pieces of metal. A certain mixture of gases used in welding is composed of carbon dioxide and argon. The partial pressure of carbon dioxide is 0.080 atm and the partial pressure of argon is 0.24 atm. What is the total pressure of the mixture.
Answer: 0.32 atm
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : =total pressure of gases = ?
= partial pressure of carbon dioxide = 0.080 atm
= partial pressure of argon = 0.24 atm
putting in the values we get:
Thus the total pressure of the gases is 0.32 atm
