Explanation:
Answer: increases by
As a chlorine atom becomes a negative ion, the atom "increases by" an electron
Explanation:
Chlorine atom has an atomic number of 17, and an electronic configuration of 1s2, 2s2 2p6, 3s2 3p5 showing 7 valence electrons in its outermost shell.
Hence, it receives a single electron to achieve a stable octet structure with electronic configuration of
1s2, 2s2 2p6, 3s2 3p6. Therefore, Cl- is a univalent negative ion with 8 valence electrons in its outermost shell. The increase is shown below
Cl + e- --> Cl-
Thus, as a chlorine atom becomes a negative ion, the atom "increases by" an electron
Answer:
The pOH of the solution is 9.92
Explanation:
pH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance. PH is defined as the negative logarithm (base 10) of the hydronium ion concentration [H₃O⁺]:
pH= - log [H₃O⁺]
So, if [H₃O⁺]=8.26*10⁻⁵, the pH is: pH=- log (8.26*10⁻⁵) ⇒ pH= 4.08
The pOH measures the concentration of OH− ions. The following relationship can be established between pH and pOH:
pH + pOH= 14
In this case, being pH=4.08 and replacing in the relationship between pH and pOH:
4.08 + pOH=14
Solving:
pOH= 14 - 4.08
pOH= 9.92
The pOH of the solution is 9.92
If you're looking for the balances equation to this the answer is
18 Ag + 3 Fe2(CO3)3 = 2 Fe3 + 9 Ag2CO3
