Answer - the degree of compactness of a substance.
Answer: Family 16 is most likely to accept 2 electrons.
Explanation:
Family 16 has the electronic configuration
. As to attain stability the p orbital will readily accept 2 electrons.
Therefore, family 16 is most likely to accept 2 electrons. Family 16 is also known as chalcogens.
Whereas, family 2 has the electronic configuration
. As the s orbital is completely filled so there is no need to accept 2 electrons.
Family 12, and family 18 has the electronic configuration
and
respectively.
Both family 12 and 18 has completely filled orbitals so it will not accept any electrons.
<em>Answer:</em>
- Conc. of K+ ions = 0.90 M
- Coc. of SO4∧-2 = 0.45 M
<em>Explanation:</em>
<em>Data Given:</em>
Conc. of H2SO4 = 0.450
As sulphoric acid is a strong electrolyte, it completely dissociate into ions.
H2SO4 ⇆ 2K+ + SO4∧-2
.450 M K2SO4 means that there is .450 mols of K2SO4 in every liter of solution.
K2SO4 : K+ K2SO4 : SO4∧-2
1 = 2 1 = 1
0.450 = 2× 0.450 = 0.90 0.450 = 0.450×1 = 0.450
<em> Result:</em>
Conc. of potassium ion will be 0.90M
Coc. of sulphate ions will be 0.45 M
