All the sublevels

Explanation:

All the sublevels of an atom with a noble gas configuration is completely filled.

Noble gases are group 8 elements which complete electron shell. They are unreactive because their atomic shells are completely filled with the right number of electons.

This gives them an inert configuration because they dont need other elements to make them stable.

<h3>Answer:</h3>

s-sub-level and p-sub-level

<h3>Explanation:</h3>

Group 18 elements in the periodic table are known as noble gases.
They have an octet configuration with their outermost s and p-sub-levels full, which makes them inert or nonreactive.
The s-sub-level takes up a maximum of 2 electrons while the p-sub-level holds a maximum of 6 electrons.
They include, argon, neon, xenon, krypton, etc.
Their electron configuration shows full outermost s and p-sub-levels.
For example; the electron configuration of Ne is 1s²2s²2p⁶, with full s and p sub-levels.

tiny-mole [99]

I think the best statement to fill the blank is that "can be desalinized and used for drinking". The said statement seems the most appropriate one because the pH of saltwater is not 10 but approximately between 7.6 to 8.4. Also, saltwater is not found in glaciers, ice caps and aquifers instead it is freshwater.

A steel container with a movable piston contains 2.00 g of helium which was held at a constant temperature of 25 °C. Additional

shtirl [24]

Answer: D) 1.00 g

Explanation:

According to the Avogadro's law, the volume of gas is directly proportional to the number of moles of gas at same pressure and temperature. That means,

$V\propto n$

or,

$\frac{V_1}{V_2}=\frac{n_1}{n_2}$

where,

$V_1$ = initial volume of gas = 2.00 L

$V_2$ = final volume of gas = 3.00 L

$n_1$ = initial moles of gas = $\frac{\text {Given mass of helium}}{\text {molar mass of helium}}=\frac{2.00g}{4g/mol}=0.500mol$

$n_2$ = final moles of gas = ?

Now we put all the given values in this formula, we get

$\frac{2.00L}{3.00L}=\frac{0.500mol}{n_2}$

$n_2=0.75mole$

Mass of helium = $moles\times {\text {molar mass}}=0.75\times 4=3.00g$

Thus mass of helium added = (3.00-2.00) g = 1.00 g

Can a substance be a Lewis acid without being a Bronsted-Lowry acid?<br> Please argue on it

makkiz [27]

Answer:

Yes. Since for a substance to be a Bronsted-Lowry acid they have to be able to donate protons, and to be a Lewis acid a substance would have to accept electrons, there are substances which cannot donate protons but can accept electrons.

Explanation:

Hope this helped!

PLZ HELP ILL GIVE BRAINLIST!

Schach [20]

Answer:

The energy of a wave is inversely proportional to the wavelength of the wave.

As wavelength increases, the energy of the wave decreases.

As wavelength decreases, the energy of the wave increases.

Explanation:

The energy of a wave is directly proportional to the wave's frequency. As frequency increases, so does the energy of the wave.

$E\propto f$ (energy $E$ is proportional to frequency $f$ )

<u>How is this related to wavelength?</u>

Frequency is inversely proportional to wavelength. That means that as frequency increases, wavelength decreases and as frequency decreases, wavelength increases.

$f\propto \frac{1}{\lambda}$ (frequency $f$ is inversely proportional to wavelength $\lambda$ )

Therefore, as wavelength increases, the energy of a wave decreases and as wavelength decreases, the energy of a wave increases.

$E\propto f\propto \frac{1}{\lambda}$
