Rock cycle - a process in which a rock forms, changes from one type of rock to another, forms again by processes on and in the Earth.
Metamorphic Rock - Rocks changed by intense heat or extreme pressure.
Sedimentary Rock - A rock that forms when sediments are compacted and cemented together.
Igneous Rock - A rock that forms when molten rock cools and hardens.
Atomic number of O= 8
Atomic number of F = 9
Electron configurations:
⁸O = 1s² 2s² 2p⁴
⁹F = 1s² 2s² 2p⁵
Total electrons: 8+ 9 = 17
For OF the molecular electron configuration would be:
OF = (1σ)²(1σ*)²(2σ)²(2σ*)²(2pσ)²(2pπ)⁴(2pπ*)³
OF⁺ suggests a loss of one electron from the 2pπ* orbital leaving the configuration as:
OF⁺ = (1σ)²(1σ*)²(2σ)²(2σ*)²(2pσ)²(2pπ)⁴(2pπ*)²
Thus, based on MO theory there are two unpaired electrons in OF⁺ ion

Answer:
0.417M
Explanation:
Equation of the reaction
2HCl+Na2CO3→2NaCl+H2O+CO2
From dilution principle
no of mole=conc × volume
from the balanced equation
no of mole of Na2CO3=2× no of mole of HCl
HCl=acid=A
Na2CO3=base=B
since n=cv
Conc of base × vol of base=2× conc of acid×volume of acid
2M×5ml=2×12M×Volume of acid
volume of acid=10/24
=0.417(3 decimal place)
