What is the primary reason that atomic radius decreases as you move from left to right across the periodic table even through th

Anika [276]

Answer:

As you move across a period the electrons are being added to the same shell. But, protons are being added as well. This makes the nucleus more positively charged and, increasing protons has a greater effect than electrons. So, there is a greater nuclear attraction and, because the electrons are being added to the same shell that shell gets pulled in more. This causes a decrease in atomic radius.

If the solubility of a gas in water is 1.22g/2.75 atm, what is it’s solubility (in g/L) at 1.0 atm

Slav-nsk [51]

Answer : The solubility of a gas in water at 1 atm pressure is, 0.4436 g/L

Solution : Given,

Solubility of a gas in water = 1.22 g/L (at 2.75 atm pressure)

At pressure = 1 atm, Solubility of a gas = ?

Now we have to calculate the solubility of a gas.

At 2.75 atm pressure, the solubility of a gas in water = 1.22 g/L

At 1 atm pressure, the solubility of a gas in water = $\frac{1atm}{2.75atm}\times 1.22g/L=0.4436g/L$

Therefore, the solubility of a gas in water at 1 atm pressure is, 0.4436 g/L
