Answer:
= 4.37*10^-9 M
Explanation:
We know that;
pH + pOH = 14
Therefore;
pH = 14 - pOH
Which means; pH = 14 - 5.64
= 8.36
But;
pH = -log[H3O+]
Thus;
8.36 = -log[H3O+]
[H3O+] = 10^(-8.36)
= 4.37*10^-9 M
The answer is decomposition, ocean release and respiration. hope this helps u :D
Answer:
There are 6.022x10^23 molecules
The oxidation number of elements in equation below are,
4NH₃ + 3Ca(ClO)₂ → 2N₂ + 6H₂O + 3CaCl₂
O.N of N in NH₃ = -3
O.N of Ca in Ca(ClO)₂ and CaCl₂ = +2
O.N of N in N₂ = 0
O.N of Cl in Ca(ClO)₂ = +1
O.N of Cl in CaCl₂ = -1
Oxidation:
Oxidation number of Nitrogen is increasing from -3 (NH₃) to 0 (N₂).
Reduction:
Oxidation number of Cl is decreasing from +1 [Ca(ClO)₂] to -1 (CaCl₂).
Result:
<span>N is oxidized and Cl is reduced.</span>
