Answer: The ground-state electronic configuration of
1)
2)
Explanation: The electronic configuration of elements is defined as the distribution of electrons around the nucleus of that element. It depends on the atomic number of the element.
Atomic number of the element = Number of electrons.
- For Ru-element
Atomic number = 44
Number of electrons = 44
Electronic configuration of Ru-element =
To form , 2 electrons are released from the neutral Ru-element.
So, the electronic configuration of
- For W-element
Atomic number = 74
Number of electrons = 74
Electronic configuration of W-element =
To form , 3 electrons are released from the neutral W-element.
So, the electronic configuration of

Explanation:
Equilibrium constant of the reaction =
Moles of
Concentration of
Moles of
Concentration of
Initial: 0.280 0.280 0
At eq'm: (0.280-x) (0.280-x) x
We are given:
Calculating for 'x'. we get:
The expression of for above reaction follows:
Putting values in above equation, we get:
On solving this quadratic equation we get:
x = 0.228, 0.344
0.228 M < 0.280 M< 0.344 M
x = 0.228 M
The equilibrium concentration of .
The equilibrium concentration of .
The equilibrium concentration of .
