No :) They see different parts but I am a little confuse when you say the same part ;P
Answer:
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s² 2s² 2p⁶, using the notation explained below.
Explanation:
Answer : The oxygen will appears in the final chemical equation as a reactant.
Explanation :
The given chemical reactions are:
(1) 
(2) 
Now we are adding reaction 1 and reaction 2, we get the final chemical equation.
The final chemical equation is:
Thus, the oxygen will appears in the final chemical equation as a reactant.
when the top of the pencil moves in one direction, the bottom end on the ground will move in another, but due to the frictional force it will move by a lesser amount, and the center of mass of the pencil will be accelerated in the horizontal direction due to the force of friction
The balanced chemical equation is:
2Fe+3H2O=Fe2O3+3H2
We are given the amount of water to be used in the reaction. This will be the starting point for the calculations.
3 mol H2O ( 1 mol Fe2O3 / 3 mol H2O ) = 1 mol Fe2O3
Therefore, the correct answer is option B.
