Answer:
Si₁₄ = 1s² 2s² 2p⁶ 3s² 3p²
Explanation:
Silicon is present in group 14 of periodic table.
It is blue-gray color metalloid.
Its atomic mass is 28 g/mol.
It is mostly used to make allow.
The most important alloy are Al-Si and Fe-Si. These are used to make different machine tools, transformer plates, engine etc.
Its atomic number is 14 and electronic configuration can be written as,
Electronic configuration:
Si₁₄ = 1s² 2s² 2p⁶ 3s² 3p²
The noble gas electronic configuration or abbreviated electronic configuration can also be written.
Si₁₄ = [Ne] 3s² 3p²
The atomic number of neon is 10. Its electronic configuration is,
Ne₁₀ = 1s² 2s² 2p⁶
That's why we write [Ne] for 1s² 2s² 2p⁶ in abbreviated electronic configuration of Si.
Ok, So bacteria and fungi are unicellular or single-celled. While Animals are multi-celled.
P= 1.50 atm
V= 3 L
R= 0.08205<span> L∙atm/mol∙K
T= 300 K
n= ?
we all this information, we can tell that we need to use ideal gas formula
PV= nRT
if we rearrange the formula for n, we get--> n= PV/ RT
let's plug in the values.
n= 1.5 x 3/ (0.08205 x 300)= 0.18 moles
