The elements in group 17 of the periodic table are all called halogens. All halogens have the same
2 answers:
<u>Answer:</u> They have same number of valence electrons.
<u>Explanation:</u>
Group 17 elements are known as halogens and these include fluorine (F), chlorine (Cl), Bromine (Br), iodine (I) and Astatine (At).
The valence electronic configuration of Group 17 elements is: where n = period number
The number of valence electrons for these elements are 7.
Hence, all the elements in Group 17 have same number of valence electrons.

At a particular temperature, the solubility of He in water is 0.080 M when the partial pressure is 1.7 atm. 4.25 atm is the partial pressure of He would give a solubility of 0.200 M.
<h3>What is Henry's Law ?</h3>Henry's Law is a gas law states that at a constant temperature the amount of gas that dissolved in a liquid is directly proportional to the partial pressure of that gas.
<h3>What is relationship between Henry's Law constant and Solubility ?</h3>The solubility of gas is directly proportional to partial pressure.
It is expressed as:
where,
= Solubility of gas
= Henry's Law constant
= Partial pressure of gas
Now put the values in above expression we get
0.080M = × 1.7 atm
= 0.047 M/atm
Now we have to find the partial pressure of He
0.200 M = 0.047 M/atm ×
= 4.25 atm
Thus from the above conclusion we can say that At a particular temperature, the solubility of He in water is 0.080 M when the partial pressure is 1.7 atm. 4.25 atm is the partial pressure of He would give a solubility of 0.200 M.
