Nimeona! Ulikuwa umeniuliza nimalizie maswali yote kwenye picha. Tayari nimejibu swali la 9(a), (b), na (c). Sasa hebu tujibu swali la 6(c).
6(c)) Ili kueleza tofauti katika upitishaji umeme wa kloridi D na E, tunahitaji kudhani miundo yao. Kwa kawaida, maswali kama haya hulinganisha kloridi ya ioni na kloridi ya kovalent.
- Kloridi D (kama kloridi ya ioni, mfano NaCl): Ina muundo wa giant ionic lattice na vifungo vya ioni. Katika hali ngumu, ioni zimefungwa mahali pake na haziwezi kusonga, kwa hivyo haipitishi umeme. Hata hivyo, inapoyeyushwa au kufutwa katika maji, ioni huwa huru kusonga na hivyo hupitisha umeme.
- Kloridi E (kama kloridi ya kovalent, mfano CCl₄): Ina muundo wa simple molecular na vifungo vya kovalent. Haina ioni huru au elektroni zilizotawanyika katika hali yoyote (ngumu, kioevu, au gesi), kwa hivyo haipitishi umeme.
Kwa hivyo, tofauti kuu ni kwamba kloridi ya ioni (D) hupitisha umeme ikiwa imeyeyushwa au katika myeyusho wa maji kutokana na ioni zinazosonga, wakati kloridi ya kovalent (E) haipitishi umeme kamwe.
