Answer : The mass of chlorine reacted with the phosphorus is, 53.25 grams.
Explanation :
First we have to calculate the moles of phosphorus.
Now we have to calculate the moles of
The balanced chemical reaction is:
From the balanced chemical reaction, we conclude that
As, 2 moles of phosphorous react with 3 moles of
So, 0.5 moles of phosphorous react with moles of
Now we have to calculate the mass of
Molar mass of = 71 g/mol
Therefore, the mass of chlorine reacted with the phosphorus is, 53.25 grams.
Answer:
Most common oxidation state of the chalcogens is -2, most common oxidation state of the halogens is -1.
Explanation:
For atomic radii, the chalcogens have a larger atomic radii than the halogens
This is because atomic radii decreases across the period due to increase in nuclear charge.
For ionic radii the chalcogens also have larger ionic radii than the halogens. This is because the chalcogens always carry a -2 charge compared to halogens that carry a -1 charge. Since -2 is the most common oxidation state for chalcogens and -1 is the most common oxidation state for the halogens.
In terms of oxidation states, the halogens show a higher value of common oxidation state -1 while for chalcogens is -2 even though +2, +4 and +6 oxidation states are also well known.
First ionization energy of halogens is greater than that of the chalcogens due to greater effective nuclear charge.
The second ionization energy of chalcogens is greater than that of the halogens.
