Answer: the solution is acidic and with a pH value of 2.7
Explanation:
The pH of a solution is the concentration of hydrogen ion concentration in the solution. Mathematically, it is expressed as pH = -log(H+), where H+ is the concentration of hydrogen ion
So, for when [H+] = 0.0023 M
pH = -log(0.0023 M)
pH = -(-2.638)
pH = 2.638 (The minus signs cancelled out)
Round the pH value to the nearest tenth as 2.7.
On the pH scale, readings are from 1 to 14, and pH values less than 7 are regarded as acidic while pH values above 7.0 are basic.
Thus, the solution is acidic and with a pH value of 2.7
Answer : The number of unpaired electrons in the = 2
The bond order of is, 2
Explanation :
According to the molecular orbital theory, the general molecular orbital configuration will be,
As there are 9 electrons present in fluorine.
The number of electrons present in molecule = 2(9) = 18 - 2 = 16
The molecular orbital configuration of molecule will be,
The number of unpaired electrons in the = 2
The formula of bond order =
The bonding order of =
The bond order of is, 2
Answer: solubility, molecular mass, and hydrogen bonding
Explanation:
Answer:
your question will be answered by your religion - if you have one - and when you go deep into the religion and really believe in it you understand your surroundings
Explanation:
Atomic mass Na = 22.99 u.m.a
22.99 g ------------------ 6.02x10²³ atoms
175 g -------------------- ?? atoms
175 x (6.02x10²³) / 22.99 => 4.58x10²⁴ atoms
hope this helps!
