Answer : The correct option is, 7.58
Explanation : Given,
pOH = 6.42
pH : It is defined as the negative logarithm of the hydrogen ion concentration.
As we know that,

Now put the value of pOH in this expression, we get the pH of this solution.




Therefore, the pH of this solution is, 7.58
Answer:
35 gm
Explanation:
What is mass of 0.6 mol C4H10
C4H10 has a molar nass of
(4X12) (10
X 1) = 48 + 10 8
so 1 mole of C4H10 is 58 gm
so 0.6 moles is
(0.6 X58) = 35 gm
Answer:
10 molecular orbitals
Explanation:
The number of atomic orbitals combined to form a molecule is the same number if molecular orbitals that will be found in the molecule. Hence, the number of orbitals are conserved. Some of these orbitals will be bonding molecular orbitals while others will be anti bonding molecular orbitals.
