  • which one will precipitate first?

    Under the right circumstances, aqueous Ag+ can be separated from aqueous Pb2+ by the difference in the solubilities of their chloride salts, AgCl and PbCl2. Ksp for AgCl is 1.8 x 10^-10. Ksp for PbCl2 is 1.7 x 10^-5.

    a. If you begin with both metal ions having a concentration of 0.0010 M, which ion precipitates first as an insoluble chloride on adding HCl?

    b. What is the concentration of the metal ion that precipitates first, just before the second metal chloride begins to precipitate?

  • What's the point of this poem?

    I don't need to know what's going on in the plot i want to know what she wrote it for like what idea is she trying to express though it?

    Because I could not stop for Death—

    He kindly stopped for me—

    The Carriage held but just Ourselves—

    And Immortality.

    We slowly drove—He knew no haste

    And I had put away

    My labor and my leisure too,

    For His Civility—

    We passed the School, where Children strove

    At Recess—in the Ring—

    We passed the Fields of Gazing Grain—

    We passed the Setting Sun—

    Or rather—He passed Us—

    The Dews drew quivering and chill—

    For only Gossamer, my Gown—

    My Tippet—only Tulle—

    We paused before a House that seemed

    A Swelling of the Ground—

    The Roof was scarcely visible—

    The Cornice—in the Ground—

    Since then—'tis Centuries—and yet

    Feels shorter than the Day

    I first surmised the Horses' Heads

    Were toward Eternity—

  • If you expose an object to heat is it releasing heat or absorbing heat?

    Is it releasing heat (because it is hot) or absorbing heat (because it is getting warmed up)?

  • Help with chemistry problem?

    (1) Predict the effects on the following actions on the system represented below. Explain your predictions. Use the colors of the solutions given to determine what you would observe in the laboratory.

    Fe3+ (aq, yellow) + SCN- (aq, colorless) ↔ FeSCN2+ (aq, red)

    (a) Addition of Fe(NO3)3

    (b) Addition of NaOH

    (c) Addition of NaCl

    (d) Addition of KSCN

    (2) Explain, using Le Chatelier’s principle, why you should expect the intensity of the red to decrease and the intensity of the yellow to increase when the system is diluted with water.

    (3) Explain the experimental steps you will take in order to determine the formation of the thiocyanatoferrate(III) ion formed in part I is an endothermic or exothermic process. (The equation for the system is given in question 1.)

  • my dad only talks about grades?

    Hi, I'm a 16 year old girl and the only time my dad will talk to me is to tell me to study more, that he's ashamed of me, and that my thighs are too big for it to be acceptable for me to wear skinny jeans. I study a lot, my school starts in september and I'm taking AP chem. so I'm reading the first 10 chapters of the text book before school starts so I'm ahead and I do the same with my math book, I'm also teaching neurology to myself and I'm going to do the same for psychology too because my dad says I have to take a different class instead. and I know my thighs are very big but I don't think I owe it to anyone for them to be small, I mean i have a thigh gap and I'm 5'3" and 108 llb that's no so big someone should tell me I can't wear skinny jeans I think, every time I start to accept my thighs I think of what my dad says and I stop. My mom is really really nice and I spend a lot of time with her but I don't like to talk to or even look at my dad. what do I do it always makes me feel like I'm not good enough and a fat stupid loser.
