To dissolve in water, aluminum (Al) should form a compound with sulfate. Aluminum sulfate is the water soluble compound of aluminum. It has a chemical formula of Al2(SO4)3. It is used in industries as flocculating agent especially in the purification steps of drinking water and wastewater treatment plants.

Why does conduction occur in solids and liquids easier compared to gases?

Option #2 because gas can take up a lot of space and the particles can spread out more. think of fog its a gas and it can spread out over a big area and its hard for the sun to shine through enough to heat it up and evaporate it.<span />

Answer:

Molecules in order of decreasing rate of effusion:

$^1{H}^{35}Cl>^2H^{35}Cl>^1H^{37}Cl>^2H^{37}Cl$

Explanation:

Mass of $^1H^{35}Cl$ gas= $M_1= 36 g/mol$

Mass of $^1H^{37}Cl$ gas = $M_2= 38 g/mol$

Mass of $^2H^{35}Cl$ gas = $M_3= 37 g/mol$

Mass of $^2H^{37}Cl$ gas = $M_4= 39 g/mol$

According Graham's law:

'The rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas'.The equation given by this law follows the equation:

$\text{Rate of diffusion}\propto \frac{1}{\sqrt{\text{Molar mass of the gas}}}$

So, higher the molecular mass of the gas lower will be the effusion rate and vice versa.

Increasing order of molecular masses of the given gases:

$M_1$

Decreasing order of effusion rate respective to gases:

$R_1>R_3>R_2>R_4$

Molecules in order of decreasing rate of effusion:

$^{1}\textrm{H}^{35}Cl> ^{2}\textrm{H}^{35}Cl>^{1}\textrm {H}^{37}Cl>^{2}\textrm{H}^{37}Cl$

KATRIN_1 [288]

It's the outermost layer of atmosphere, it's thin, but it's said to absorb harmful radiation coming from the Sun, which is really important considering Sun's radiation could melt down the DNA of almost all form of life.
