Sulfur is a group six element in period 3 with atomic number 16 and an electronic configuration of 2:8:6. Therefore, to attain a stable configuration it requires to gain two electrons forming an ion with a charge of -2. The negative charge is due to the gaining of electrons.
I believe the correct response would be D. At least 2 of the above statements are correct.
Answer:
Explanation:
The arrow symbol in a chemical equation separates the reactants from products. A chemical reaction is process in which chemical changes leads to the formation of products from reactants.
Answer:
Thus the order of covalent character will be
DG < EG < DF < DE
Explanation:
The electronegativity decides the nature of bond formed between two atoms.
More the difference in electronegativity more the ionic character in the bond formed.
Let us check the electronegativity difference between the elements forming molecules
a) DE :
3.8-3.3 = 0.5
b) DG :
3.8-1.3 = 2.5
c) EG
3.3-1.3 = 2
d) DF
3.8-2.8 = 1.3
So the maximum ionic character will be in DG and minimum in DE
Thus the order of covalent character will be
DG < EG < DF < DE
Answer: Concentration of 
at equilibrium = 0.08 M
Concentration of 
at equilibrium =0.08 M
Concentration of 
= 0.64M
Explanation:
Moles of 
= 4.00 mole
Volume of solution = 5.00 L
Initial concentration of =
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
For the given chemical reaction:
Initial conc. 0.8 M 0 M 0 M
At eqm. conc. (0.8-2x) M (x) M (x) M
The expression for is written as:
![K_c=\frac{[H_2]^1[I_2]^1}{[HI]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BH_2%5D%5E1%5BI_2%5D%5E1%7D%7B%5BHI%5D%5E2%7D)
Concentration of at equilibrium = x M = 0.08 M
Concentration of at equilibrium = x M = 0.08 M
Concentration of = (0.8-2x) =
