Answer:

CH3O- , BrF4- and NH4+ have tetrahedral geometry on the basis of their electron domain geometry..

Explanation:

The object on the picture as shown on the fig below describes a compound with a total of 4 pair electron domain with it's electron domain typically described as tetrahedral.

The task is to sort out which of those in the options fort into the category.

Although NH3 and NH4+ ion both have the SP3 hybridization their electron pair geometry differs. In the NH3 molecule one lone pair and three bond pairs are present. While Distortion is caused by repulsion between lone pair and bond pair the geometry of NH3 causes it to become pyramidal in NH4+ irrespective of possessing the sp3 hybridization.

Its resulting trigonal pyramidal geometry is thus described as tetrahedral. It consequently has 3 bonding domains and 1 nonbinding domain.

CH3O- is also tetrahedral with an idealized bond angle of 109.5°.

BrF4- It has 4 bond pair present hence the tetrahedral geometry. The presence of two lone pair makes it square planar described sometimes as AE2X4. It has 6 electron regions.

C2Cl4 has a linear geometry it has one triple bond and two single bonds this giving hints that its coordinate and steric number is 2 and its bond angle is 180°.

So, CH3O- , BrF4- and NH4+ have tetrahedral geometry

Answer:

NH^{+} _{4}  ammonium ion.

Explanation:

Check the box next to each molecule on the right that has the shape of the model molecule on the left: model molecules (check all that apply X 5 ? | O CH20 CNH, You can drag the slider to rotate the model molecule. + 1 O Brf 4 CH2Cl2 Note for advanced students: the length of bonds and size of atoms in the model is not necessarily realistic. The model is only meant to show you the general geometry and 3D shape of the molecule.

when you look at the diagram from the source page

one can conclude that the diagram is tetrahedral and the angle between the molecules is 109.5 deg

There is one central atom bonded to four atoms in a tetrahedral molecule .it has no lone electron pairs.m

NH4+ is the answer

Other molecules that are tetrahedral in shape are methane ion and phosphate ion.

<h2>Hello!</h2>

The answer is:

The new volume is 2.84 L.

V_{2}=2.84L

<h2>Why?</h2>

To solve the problem, we need to remember what STP means. STP means that the gas is at standard temperature and pressure, or 273.15 K (0°C) and 1 atm.

Also, we need to use the Combined Gas Law, since the temperature, the pressure and the volume are being changed.

The Combined Gas Law establishes a relationship between the temperature, the pressure and the volume of an ideal gas using , Gay-Lussac's Law, Charles's Law,  and Boyle's Law.

The law is defined by the following equation:

\frac{P_{1}V{1}}{T_{1}}=\frac{P_{2}V{2}}{T_{2}}

Where,

P_{1} is the first pressure.

V_{1} is the first volume.

T_{1} is the first temperature.

P_{2} is the second pressure.

V_{2} is the second volume.

T_{2} is the second temperature.

So, we are given the following information:

V_{1}=2L\\P_{1}=1atm\\T_{1}=0\°C=273.15K\\P_{2}=80kPa=0.8atm\\T_{2}=37\°C=37+273=310K

Then, isolating the new volume, and substituting, we have:

\frac{P_{1}V{1}}{T_{1}}=\frac{P_{2}V{2}}{T_{2}}\\\\V_{2}=\frac{P_{1}V{1}}{T_{1}}*\frac{T_{2}}{P_{2}}\\\\V_{2}=\frac{1atm*2L}{273.15K}*\frac{310K}{0.8kPa}=2.84L

Hence, the new volume is 2.84 L.

V_{2}=2.84L

Have a nice day!

at which type of plate boundary do most earthquakes occur? A.convergent B.transform C.divergent D.trench
tino4ka555 [31]

Answer: A. convergent

Most earthquakes occur at the boundary where two plates meet. This phenomena is called as convergent plate tectonics. In this phenomena the two plates moves towards each other. If the plates are of equal density then they will push each other but if they are of unequal density, the denser plate sink beneath the other plate.

Determine the volume of fluid in the graduated cylinder shown.
Sladkaya [172]

Answer:

22.5 mL

Explanation:

We are given an amount of a fluid in a graduated cylinder and required to determine its volume.

Liquids always take the shape of the container they are placed in. In the graduated cylinder shown, note how the top of the fluid curves downwards. The volume of the liquid is usually determined at the bottom of this curve or what is called the meniscus.

The bottom of the meniscus is at the 22.5 mL level and thus the volume of the fluid is 22.5 mL
