Answer:
5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur
Explanation:
The balanced equation in this question is
Iron + Sulfur = Iron(II) Sulfide
Fe (II) + S --> Fe(II)S
Thus one mole of sulfur reacts with one mole of Fe(II)
Hence, 5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur
Moles of Zn present= 2.36/65.4= 0.0361 moles
Therefore maximum moles of ZnO= 0.0722
Mass of one mole of ZnO= 81.4
Mass of ZnO produced= 0.0722 x 81.4= 5.87g
The element is silicon (Si). It forms minerals like quartz and rocks such as granite.
The answer is potassium. It would be 4, and for neon would be 2. Just total which row of the periodic table you are on. The "L" tells you whether the highest-energy electron is in an "s" orbital (L=0) or a "p" orbital (L=1) or a "d" orbital (L=2) or an "f" orbital (L=3). The way in which these orbitals are filled is: for each of the first three rows (up to argon), two electrons in the "s" orbital are filled first, then 6 electrons in the "p"orbitals. The row where the potassium also starts with filling the "s" orbital at the new "n" level (4) but then goes back to satisfying up the "d" orbitals of n=3 before it seals up the "p"s for n=4.
