1 answer:

4 0

The electron group arrangement of CF₄ is penta-atomic. The molecular shape is tetrahedral, and the bond angle is 109.5°.

<h3>What is the electron group arrangement?</h3>

Electron group arrangement is the arrangement of the electron of a compound. This is the geometry of the structure of the compounds. The different types of arrangements are, trigonal planar, tetrahedral, trigonal bipyramidal, or octahedral.

The carbon tetrafluoride has a tetrahedral structure, with a bond angler of 109.5°.

Thus, the electron group arrangement of CF₄ is penta-atomic. The molecular shape is tetrahedral, and the bond angle is 109.5°.

Helga [31]

Answer: Membrane Protiens

Explanation:

In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.

What is a mole? in your own words. (6.02x10^23)

Luda [366]

Answer:

Like all units, a mole has to be based on something reproducible. A mole is the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles is Avogadro's Number, which is roughly 6.02x1023. 1 A mole of carbon atoms is 6.02x1023 carbon atoms

A piece of aluminum weighing 10.0 grams is placed into a graduated cylinder that has an initial volume (before immersion) of 35.

padilas [110]

Answer:

The density of the metal sample is 2.70 $\frac{grams}{mL}$

Explanation:

Density is a magnitude that allows you to measure the amount of mass in a given volume of a substance. Then, the expression for the calculation of density is the ratio between the mass of a body and the volume it occupies:

$d=\frac{m}{V}$

Density, according to the International System of Units, is usually expressed in kilograms per cubic meter (kg / m3) or gram per cubic centimeter (g / cm3). Although it can also be expressed in any other unit of mass by volume.

So, for the calculation of density you know that:

mass of the sample= 10 grams
volume of the sample = volume on the cylinder after immersion - volume on the cylinder before immersion= 38.7 mL - 35.0 ml = 3.7 mL

Then:

$d=\frac{10 grams}{3.7 mL}$

d=2.70 $\frac{grams}{mL}$

The density of the metal sample is 2.70 $\frac{grams}{mL}$

If you use one more of N2 how many moles of NH3 could be produced?

mote1985 [20]

Hey there!

2 moles will be produced.

In N₂ there are 2 nitrogen atoms. In NH₃ there is 1 nitrogen atom.

So, there will be twice as many moles produced because there will be twice as many molecules.

Hope this helps!
