Argon makes up 0.93% by volume of air. Calculate its solubility (in mol/L) in water at 20°C and 1.0 atm. The Henry's law constan

ivolga24 [154]

Answer : The solubility is, $1.4\times 10^{-5}mol/L$

Explanation : Given,

$k_H$ = Henry's law constant of argon = $1.5\times 10^{-3}mol/L.atm$

First we have to calculate the pressure of argon.

Pressure of argon = $1.0atm\times \frac{0.93}{100}$

Pressure of argon = 0.0093 atm

Now we have to calculate the solubility.

As, the solubility of argon in 1 atm pressure = $1.5\times 10^{-3}mol/L$

So, the solubility of argon in 0.0093 atm pressure = $\frac{0.0093atm}{1atm}\times 1.5\times 10^{-3}mol/L$

= $1.4\times 10^{-5}mol/L$

Thus, the solubility is, $1.4\times 10^{-5}mol/L$

According to the octet rule, an atom with two electron shells is most stable when it contains eight

Lorico [155]

According to the octet rule, an atom with two electron shells is most stable when it contains eight electrons. The octet rule is always based on valence electrons and their tendency to form bonds. <span />

What is the balanced equation for the combustion of magnesium?

Lostsunrise [7]

Answer:

2Mg + O2 → 2MgO

Explanation:

In all conbustion you should know, that reactans are an specific compound and O2, so the products must be CO2 and H2O, or in this case, the corresponding oxide.

What’s the mass of a substance that’s density is 100.09g/mL and takes up 52.75mL?

Leokris [45]

Answer: 5,279.7475g

Mass = Density x Volume
Fill in the blanks :D
Mass= 100.09g/mL x 52.75mL

The mL cancels out and you multiply the numbers.
Mass= 5,279.7475 g
