How many molecules of F2 are there in 4.2 mol F2?

Chemistry
1 answer:
zhannawk [14.2K]3 years ago
7 0

Hey there!

1 mol has 6.022 x 10²³ molecules.

If we have 4.2 mol F₂, multiply the number of molecules in 1 mol by 4.2.

4.2 x 6.022 x 10²³

2 sig figs

25 x 10²³

Put this properly into scientific notation.

2.5 x 10²⁴ molecules of F₂

Hope this helps!

A 0.5 kg ball rolls down a frictionless inclined plane. The height of the inclined plane is 0.5m. What is the kinetic energy of
joja [24]

Answer:

2.45Joules

Explanation:

since kinetic energy is K.E.=1/2mv^{2}

lost in potential energy is gain of kinetic energy

mgh=1/2mv^2

9.8*2*0.5=v^2

v^{2}=9.8

v=\sqrt{9.8} =3.13m/s

now k.e. = 0.5*m*v^{2} =0.5*0.5*9.8 =2.45J

What is the hybridization of the central iodine atom in i3−?
Ainat [17]
The central iodine atom in triiodide has sp3d hybridization.In triiodide anion, the central iodine atom has three equatorial lone pairs of electrons and the terminal iodines are bonded axially in a linear shape. Electrons in sp3d hybridization are arranged in trigonal bipyramidal symmetry.
Explanation:

When you draw the Lewis structure of this particle, you'll realize that the central I atom has a pair of bonds and three individual pairs of electrons. as a result of there are five things around that central I atom, it's<span> sp3d hybridized.

The bonds during a gas<span> (CH4) molecule </span>are fashioned<span> by four separate </span>however<span> equivalent orbitals; </span>one<span> 2s and </span>3<span> 2p orbitals of the carbon </span>interbreed<span> into four sp3 orbitals. </span>within the<span> ammonia molecule (NH3), 2s and 2p orbitals </span>produce<span> four sp3hybrid orbitals, </span>one among that<span> is occupied by a lone </span>try<span> of electrons.</span><span>

The glancing angle (θ) of a Bragg reflection (n = 1) from a set of crystal planes separated by 99.3 pm is 10.42°. Calculate the
Rufina [12.5K]

Answer:

wavelength λ =  35.92 pm

Explanation:

Given that:

The glancing angle (θ) = 10.42°

Bragg reflection n = 1

wavelength λ = ???

diameter d = 99.3 pm

Using the formula:

nλ = 2dsinθ

we have:

1 × λ = 2 × ( 99.3) × sin (10.42°)

λ =  198.6 × 0.18086

λ =  35.92 pm
