On the periodic table, the size of an element's ionic radius follows a predictable trend. The ionic radius increases as you shift down a column or community. This is because every row introduces a new shell of electrons. The ionic radius decreases over a row or time, going from left to right.
Answer:
3
Explanation:
If we want it to be rounded to one significant figure, it will be 3.
Answer:
Vsln=13.2mL
Explanation:
MwPb(NO3)2=331.2g/mol
⇒ Vsln = (1L Pb(NO3)2/0.200molPb(NO3)2) * (molPb(NO3)2/331.2gPb(NO3)2) * 0.875gPb(NO3)2
⇒ Vsln = 0.0132L (13.2mL)
