Explanation:
The distribution of electrons of an atom or molecule in an atomic orbital is called electronic configuration.
1. The electronic configuration of Fluorine: [He] 2s²2p⁵.
2. The electronic configuration of Neon: [He]2s²2p⁶
3. The electronic configuration of Sulfur: 1s²2s²2p⁶3s²3p⁴
4. The electronic configuration of Calcium:[Ar] 4s²
5. The electronic configuration of Iron: [Ar] 3d⁶4s²
Hence, this is the required solution.
Answer:Because of the rapid changes in altitude and temperature along a mountain slope, multiple ecological zones are “stacked” upon one another sometimes ranging from dense tropical jungles to glacial ice within a few kilometres
Explanation:
Answer:
a
Explanation:
its the only thing witth electric energy, the rest are magnetic energy
CoCl₂(s) → Co²⁺(aq) + 2Cl⁻(aq)
n(CoCl₂)=0.27 mol
n(Co²⁺)=n(CoCl₂)
n(Cl⁻)=2n(CoCl₂)
n=n(Co²⁺)+n(Cl⁻)=3n(CoCl₂)
n=3*0.27=0.81 mol
it would be B when air temperature decreased, soil temperature increased.
