If the solutes are dispersed evenly in their particular solvent we say that the solution has reached diffusion I believe.
The decomposition of CCl4 is as follows:
CCl4 (g) ---> C(s) + 2Cl2 (g) Kp = 0.76
where Kp = (PCl2)^2 / (P_CCl4)
P_C is zero since carbon is in solid form.
Express P_CCl4 in terms of P_Cl2
0.76 = (P_Cl2)^2 / (P_CCl4)
0.76P_CCl4 = (P_Cl2)^2
Ptotal = P_Cl2 = 1.9 atm
Solve for P_CCl4
P_CCl4 = 4.75 atm<span />
All group 7 elements are members of the halogen family, seen on the periodic table of elements. Such as : F, Cl, Br.
Answer:
See explanation.
Explanation:
1. There are 8 electrons. Elements that end with 2p orbitals are in the 2nd period (aka row) of the periodic table. Elements that have 4 electrons in 2p are in the 16th group (aka column) (column 16 may also be referred to as 6A) of the periodic table. So looking at row 2, column 16, we can see that the first diagram is of O, Oxygen.
2. 8 electrons. This is the same diagram as the one above.
3. 13 electrons. Elements ending with 3p are in period 3. Elements with 1 valence electron in a p orbital are in group 13 (aka group 3A).
4. 7 electrons. We already know 2p is period 2. 3 valence electrons in a p orbital means that it is in group 15/group 5A.
I did not write the answers for #3 and 4 but they can be easily found on a periodic table with the info I gave.
A covalent bond is a bond between 2 non metals, they share electrons. Ionic bonding occurs between a metal and a non-metal, and they transfer electrons.
