Answer:
8.00 moles.
Explanation:
The ratio of Fe to FeO is 2:2 = 1:1, so 8 moles are produced.
Answer:
True => (3, 2, 0, -1/2) => 3d₀² electron
Explanation:
Answer:
Explanation:
An atom is the smallest indivisible particle that takes part in any chemical reaction. They are easily identified distinctively as elements in a compound.
The subscripts accompanying a chemical symbol shows the number of atoms of elements combining to give a compound:
Compound Elements Number of atoms
KBr K Br 2
C₁₂H₂₂O₁₁ 12(C) 22(H) 11(O) 12 + 22 + 11 = 45
KAlSi₃O₈ 1(K) 1(Al) 3(Si) 8(O) 1 + 1 + 3 + 8 = 13
Ag₃PO₄ 3(Ag) 1(P) 4(O) 3+ 1 + 4 = 8
CH₃CO₂C₆H₄COOH 9(C) 8(H) 4(C) 9+8+4 = 21
Really good question i hope to see the answer to
Octet rule states that an atom or element in the periodic table tends to combine with other atoms or elements and tries to attain 8 electrons in the outermost shell like the noble gas to attain stability.
1. So those elements which can easily attain octet rule are highly active.
eg: Sodium and chlorine.
Sodium has one outermost electron and can attain octet rule by losing this one electron
Chlorine has 7 outhermost electron and can attain octet rule by gaining one electron.
So Sodium and Chlorine are highly active as they can easily attain stability by losing or gaining one electron to attain octet.
2. And thus octet rule easily explains why an element or atom is highly active.
