Molar mass O₂ = 16 * 2 = 32.0 g/mol

1 mol -------- 32.0 g
? mol -------- 24.0 g

mol = 24.0 * 1 / 32.0

= 0.75 moles

1 mol ------- 22.4 L ( at STP )
0.75 moles --- ?

v = 0.75 * 22.4 / 1

v = 16.8 L

hope this helps!

Answer:

Option B

Explanation:

For the problem in question 12, option B is the correct choice. It rightly expresses how electrons will fill the third energy level of aluminum.

Aluminum is an element with 13 electrons. It has 3 energy levels.

The shell notation is given as 2 8 3

Sublevel notation = 1s² 2s² 2p⁶ 3s² 3p¹

The third energy level is given as 3s² 3p¹

We can represent it as: ⇅ ↑

3s² 3p¹

Covalent bonds in a molecule absorb radiation in the IR region and vibrate at characteristic frequencies.

vazorg [7]

Answer:

$Frequency=1.6\times 10^{12}\ Hz$

Explanation:

The relation between frequency and wavelength is shown below as:

$c=frequency\times Wavelength
$

c is the speed of light having value $3\times 10^8\ m/s$

Given, Wavelength = 188 μm

Also, 1 μm = $10^{-6}$ nm

So,

Wavelength = $188\times 10^{-6}$ m

Thus, Frequency is:

$Frequency=\frac{c}{Wavelength}$

$Frequency=\frac{3\times 10^8}{188\times 10^{-6}}\ Hz$

$Frequency=1.6\times 10^{12}\ Hz$
