All organic molecules must have carbon and hydrogen so it would be choice A
Here is your answer
Ru(MnO4)2
We know that
valency of Ru=2
Valency of permanganate(MnO4)= 1
So, on combining the two
Ru(MnO4)2 is obtained by transferring of electrons.

Answer:
d.3.0
Explanation:
Step 1: Calculate the final volume of the solution
The final volume is equal to the sum of the volumes of the initial HCl solution and the volume of distilled water.
V₂ = 100 mL + 100 mL = 200 mL
Step 2: Calculate the final concentration of HCl
We will use the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁/V₂ = 0.002 M × 100 mL/200 mL = 0.001 M
Step 3: Calculate the pH of the final HCl solution
Since HCl is a strong acid, [H⁺] = HCl. We will use the definition of pH.
pH = -log [H⁺] = -log 0.001 = 3
I think it would be D because it makes the most sense
