D because velocity has direction in the formula (I think)
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.
In 1 mole = 6.022 * 10^23 molecules of CO2
In 1.75 mole = 6.022 * 10^23 * 1.75
=10.53 * 10^23.
I hope this helps.
