I believe the answer is C.
Answer:
Aluminum iodide (AlI₃)
Explanation:
The synthesis reaction of aluminum (Al) and iodine (I) can be illustrated as shown below:
Aluminium exhibit trivalent positive ion (Al³⁺)
Iodine exhibit univalent negative ion (I¯)
During reaction, there will be an exchange of ion as shown below:
Al³⁺ + I¯ —> AlI₃
Thus, we can write the balanced equation for the reaction as follow:
Al + I₂ —› AlI₃
There are 2 atoms of I on the left side and 3 atoms on the right side. It can be balance by putting 2 in front of AlI₃ and 3 in front of I₂ as shown below:
Al + 3I₂ —› 2AlI₃
There are 2 atoms of Al on the right side and 1 atom on the left side. It can be balance by putting 2 in front of Al as shown below:
2Al + 3I₂ —› 2AlI₃
Thus the equation is balanced.
The product on the reaction is aluminum iodide (AlI₃)
Answer:
D.A-C would have the same number of atom
The phrasing of this exercise means that we have to exclude 3 out of the 4 choices.
We have that the 4 quantum numbers that an electron has are the defining numbers of that electron. The first coordinate, the principal quantum number ncan take any positive value since it defines the shell in which that electron is.
The second number is called the orbital angular momentum number and takes the values from 0 to n-1 (the integer ones) where n is the principal number. Hence, we can disqualify options 1 and 4; the 1st because the principal and the orbital number are the same which is not possible and the 4th because the orbital number is negative which is not possible.
The third is the magnetic quantum number and takes values from -l to l (all integer values in between). Hence, it cannot be equal to n again, so option 2 is disqualified too.
The only remaining option that is correct is 3)
P.S. We have a 4th number, the spin number; this number can assume only the values +1/2 and -1/2
