Sodium Oxide ---> Na2O
Calcium Chloride ---> CaCl2
Potassium Sulfide ---> K2S.
I hope this helps! :)
It could both the 2nd and the 3rd,
because if you add the exponents (2 + 1 + 6 = 9) you don't get 10.
and also each orbital level can and has to carry 2 electrons, and the 2s only has 1 there.
This can be solved according to Le C ha.tellors principle
- Any change in concentration, temperature, pressure can shift the equilibrium
So
Here to increase NO_2
We need to increase the temperature or increase the concentrations of reactants
If you mean chlorate it would be Pb(CLO3)3
If you mean chromate it would be
Pb(CrO4)3
