Answer:
For me, it is balanced
Explanation:
Because the amount of element Zn reaction is equal the production. Also as the amount of Hydrogen and Chloride in the reaction and the production are equal.
For a) [Ru(NH₃)₅Cl]SO₄
Ru configuration = d⁶s²
In this complex Ru oxidation number is +3
Ru³⁺ configuration = d⁵
number of
electrons = 5
For b) Na₂[Os(CN)₆]
Os configuration = d⁶s²
In this complex Os oxidation number is +4
Os⁴⁺ configuration = d⁴
number of
electrons = 4
Answer:
C. 1.62.
Explanation:
∵ pH = - log[H⁺],
[H⁺] = 0.024 M.
∴ pH = - log(0.024) = 1.62.
<em>So, the right choice is: C. 1.62.</em>
Fresh water= 1%
Salt water= 99%
