Answer: See attachment.
Explanation:
Exceptions to the octet rule fall into three categories:
- An incomplete octet.
- An odd number of electrons.
- More than eight valence electrons around the central atom.
In addition to the 3<em>s</em> and 3<em>p</em> orbitals, x<u>enon also has 3</u><u><em>d</em></u><u> orbitals that can be used in bonding</u>. These orbitals enable xenon to form an expanded octet.
Answer:
The answer to your question is below
Explanation:
a) HCl 0.01 M
pH = -log [0.01]
pH = - (-2)
pH = 2
b) HCl = 0.001 M
pH = -log[0.001]
pH = -(-3)
pH = 3
c) HCl = 0.00001 M
pH = -log[0.00001]
pH = - (-5)
pH = 5
d) Distilled water
pH = 7.0
e) NaOH = 0.00001 M
pOH = -log [0.00001]
pOH = -(-5)
pH = 14 - 5
pH = 9
f) NaOH = 0.001 M
pOH =- log [0.001]
pOH = 3
pH = 14 - 3
pH = 11
g) NaOH = 0.1 M
pOH = -log[0.1]
pOH = 1
pH = 14 - 1
pH = 13
<u>Answer:</u> The mass percent of NaBr in the solution is 10.18 %
<u>Explanation:</u>
To calculate the mass percentage of calcium ions in milk, we use the equation:
We are given:
Mass of solution = 270.0 g
Mass of NaBr = 27.50 g
Putting values in above equation, we get:
Hence, the mass percent of NaBr in the solution is 10.18 %
