The solubility of a saturated solution of Pb(NO3)2 at 10 °C is 46.0 g in 100 g of water. Which of the following concentrations would represent an unsaturated
solution?

60.0 g Pb(NO3)2 in 100 g of water
50.0 g Pb(NO3)2 in 100 g of water
40.0 g Pb(NO3)2 in 100 g of water
100.0 g Pb(NO3)2 in 100 g of water

neutrons are in the middle of the atom and the electrons, which are much smaller.

the millers tale is the answer.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

let that person have a turn to speak : )
