Answer: The ground-state electronic configuration of
1) ![Ru^{2+}=[Kr]4d^6](https://tex.z-dn.net/?f=Ru%5E%7B2%2B%7D%3D%5BKr%5D4d%5E6)
2) ![W^{3+]=4f^{14}5d^3](https://tex.z-dn.net/?f=W%5E%7B3%2B%5D%3D4f%5E%7B14%7D5d%5E3)
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.
Atomic number = 44
Number of electrons = 44
Electronic configuration of Ru-element = ![[Kr]4d^75s^1](https://tex.z-dn.net/?f=%5BKr%5D4d%5E75s%5E1)
To form 
, 2 electrons are released from the neutral Ru-element.
So, the electronic configuration of
Atomic number = 74
Number of electrons = 74
Electronic configuration of W-element = ![[Xe]4f^{14}5d^46s^2](https://tex.z-dn.net/?f=%5BXe%5D4f%5E%7B14%7D5d%5E46s%5E2)
To form 
, 3 electrons are released from the neutral W-element.
So, the electronic configuration of ![W^{3+}=[Xe]4f^{14}5d^3](https://tex.z-dn.net/?f=W%5E%7B3%2B%7D%3D%5BXe%5D4f%5E%7B14%7D5d%5E3)
Greetings!
I believe the answer is true.
While precipitation does require a lot of energy, evaporation takes longer, and requires more energy from heat, whereas precipitation doesn't really require any.
Hope this helps you!

Answer:
x = 1 x 10⁻²
Explanation:
Since the pH is the same in both cases, the two expressions for pH can be set equal to each other:
pH = 4 + log(x) = -log[H⁺]
The hydrogen ion concentration ([H⁺]) is 0.01 M, so this value can be substituted in the equation:
4 + log(x) = -log(0.01)
4 + log(x) = 2
log(x) = -2
x = 10⁻²
The theory that describes the motion and force driving earth's plates is Plate tectonics
Explanation:
Plate tectonics states that the outer shell of the Earth is divided into plates that glide and move over the mantle which is the surface of the earth.
The mantle is the rocky inner layer above the core of the Earth.
Plate tectonics helped the geologists to explain how continents could move around the planet.
There are 9 major plate tectonics , namely North American, Pacific, Eurasian, Australian, African, Indo - Australian,Indian South American and Antarctic. These plates have been named after the land form found on them.
