16- counting by fours

The correct answer is weight.

Answer:

it was spontaneous.

explanation:

"ain't i a woman? " is the name given to a speech, delivered extemporaneously, by sojourner truth, (1797–1883), born into slavery in new york state.sojourner truth' delivered her famous speech "ain't i a woman? " (which did not have a title at that moment) was given without any previous preparation. her dissertation took place at the women's convention in akron, ohio, in 1851.

Caso4(s) < > ca+2 + so4^-2 ksp = [ca+2][so4^-2] = 2.4 x 10^-5 = [0.20][so4^-2] [so4^-2] =1.2 x 10^-4 ag2so4(s) ,> 2ag+ + so4^-2 ksp = [ag+]^2[so4^-2] = 1.5 x 10^-5 = (0.30)^2[so4^-2] [so4^-2] = 1.5 x 10^-5/0.09 = 1.7 x 10^-4 caso4 would precipitate first since it requires less so4^- to form a saturated solution.  i believe this is right, i hope it !
