Zinc hmoov yog ntxiv rau kev daws ntawm iodine hauv ethanol. Ib qho exothermic redox cov tshuaj tiv thaiv tshwm sim , tsim zinc iodide , uas tuaj yeem tau txais los ntawm evaporating cov kuab tshuaj. Qhov kev sim tuaj yeem txuas ntxiv los qhia qhov decomposition ntawm ib qho chaw rau hauv nws cov ntsiab lus los ntawm electrolysing zinc iodide.

Yog li ntawd, zinc iodide siv rau dab tsi?

Zinc iodide feem ntau yog siv li ib qho x-ray opaque penetrant nyob rau hauv industrial radiography los txhim kho qhov sib piv ntawm kev puas tsuaj thiab cov khoom tsis zoo.

Tsis tas li ntawd, yog vim li cas iodine yog txwv tsis pub reactant nyob rau hauv zinc iodide? Hauv lwm lo lus, thaum tag nrho cov iodine tau reacted, tseem yuav muaj zinc hlau sab laug. Iodine yog cov txwv reactant . Qhov ntxiv ci, xim nyiaj xim zinc yuav raug tshem tawm ntawm cov tshuaj tiv thaiv; nws cov huab hwm coj yuav tsis suav nrog hauv kev suav ntawm cov qauv empirical. Peb xav tau cov qauv molecular ntawm zinc iodide.

Tsuas yog li ntawd, koj yuav ua li cas zinc iodide?

Koj yuav synthesize zinc iodide los ntawm kev sib xyaw elemental zinc thiab iodine hauv dej (uas dissolves lub zinc iodide cov khoom thiab tso cai rau cov tshuaj tiv thaiv mus rau ntawm tus nqi nrawm dua). Koj yuav saib xyuas cov reactant uas tshuav (tsis txwv).

Muaj pes tsawg grams zinc reacts?

53g 2.99 ib g 3.65 g 3.52 g 12) Moles of Zinc reacted : Atomic loj ntawm zinc = 65.39 g Grams ntawm zinc reacted = 0.53 g Moles ntawm zinc reacted = 0.53 g 65.39 g =.
