Give the oxidation state of the metal species in each complex. ru(cn)(co)4 -
kogti [31]
The given complex ion is as follow,

                                              [Ru (CN) (CO)₄]⁻

Where;
            [ ]  =  Coordination Sphere

            Ru  =  Central Metal Atom  =  <span>Ruthenium

            CN  =  Cyanide Ligand

            CO  =  Carbonyl Ligand

The charge on Ru is calculated as follow,

                               Ru + (CN) + (CO)</span>₄  =  -1
Where;
            -1  =  overall charge on sphere

             0  =  Charge on neutral CO

            -1  =  Charge on CN

So, Putting values,


                               Ru + (-1) + (0)₄  =  -1

                               Ru - 1 + 0  =  -1

                               Ru - 1  =  -1

                               Ru  =  -1 + 1

                               Ru  =  0
Result:
          <span>Oxidation state of the metal species in each complex [Ru(CN)(CO)</span>₄]⁻ is zero.

If the H3O is 4.950 x 10-12 what is the ph?
romanna [79]

Answer:

pH = 11.3

Explanation:

From the question given above, the following data were obtained:

Concentration of hydronium ion [H₃O⁺] = 4.950×10¯¹² M

pH =.?

The pH of a solution is defined by the following equation:

pH = –Log [H₃O⁺]

Thus, with the above formula, we can obtain the pH of the solution as follow:

Concentration of hydronium ion [H₃O⁺] = 4.950×10¯¹² M

pH =.?

pH = –Log [H₃O⁺]

pH = –Log 4.950×10¯¹²

pH = 11.3

In one or two sentences, explain why the combined weight of several liquids mixed in an open flask can be less than but never mo
olga55 [171]

Answer: The law of conservation of mass states that mass is neither created or destroyed, so the combined mass of all the products after the reaction will be the same as the mass of all the reactants and never more, but since the flask is not closed, the gases produced from the reaction will move into the atmosphere and the product left behind , the solids and/or liquids, will be the only products that you’ll end up weighing, meaning it’ll be less weight than the original reactants. The reason I’m interchanging weight and mass is because although weight changes with gravity, so long as the gravitational force stays constant throughout the experiment, it’s pretty much the same.
