How many moles of lead chloride are formed?
Complete Step-by-Step Answer:
And one mole of PbO corresponds to the formation of one mole of lead (II) chloride. Hence by this ratio 0.029 moles of PbO can form 0.029 moles of lead (II) chloride.
Why does lead form 2+ and 4+ ions?
The inert pair effect in the formation of ionic bonds
If the elements in Group 4 form 2+ ions they lose their p electrons leaving the s2 pair unused. For example to form a lead(II) ion lead loses its two 6p electrons but the 6s electrons are left unchanged an “inert pair”.
