There can be two electrons in one orbital maximum. The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max.
Answer:
The number of electrons I think
Explanation:
Answer:
2 CO + O2 ———————-> 2 CO2
Mass of CO = 174 g
First change it into moles
No of moles = (mass in grams)/molar mass
Molar mass of CO = 30 g/mol
No of moles of CO = 174/30 = 5.8 mol
2 CO + O2 ———————-> 2 CO2
Equation shows that
2 moles of CO react with moles of O2 = 1 mol
1 mole of CO react with moles of O2 = 1/2
1 mole of CO react with moles of O2 = 0.5 mol
5.8 mole of CO react with moles of O2 =0.5x5.8
5.8 mole of CO react with moles of O2 = 2.9 mol
No of moles of O2 used = 2.9 mol
Then change it into no of molecules
No of molecules of O2 = 2.9x6.02x10^23
No of molecules of O2 used = 17.45x10^23
