A field force is a force that acts equally on all the items in it. For example, the force you exert on the chair when you push it acts only on the chair - not on the table, other chairs, etc. around it. Whereas a force like gravity acts equally on everything - on the apple, on the leaves, on the other apples in the tree, etc
When global winds, ocean currents, and other forces move freely across the earths surface.
Reaction for precipitation is
Pb(NO3)2(aq) + 2Nacl(aq)→PbCL2(s)+2NaNO3(aq)
The given reaction is
The mol of Nacl required is =2×mol of Pb(NO3)2 which is present.
∴M(Nacl)×V(Nacl) =2×M(Pb(NO3)2 ×V(Pb(NO3)2
o.100M×V(Nacl)=2×0.200 MX75.0ML
V(Nacl = 300mL.

This is the only answer that can be observed without testing gear and with the naked eye.... Hope I helped ^-^</span>
