4. If 20.0 mL of 0.10 M Ba(NO)3 are added to 50.0 mL of 0.10 M Na2CO3, will BaCO3 precipitate? (Ksp BaCO3 = 8.1x10^-9)

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
