Hapa kuna majibu kwa maswali yako: c) Hasara mbili za mwali unaotoa mwangaza ni: • Huzalisha masizi (kaboni) ambayo yanaweza kuchafulia vifaa. • Huwa na joto dogo na hivyo si mzuri kwa kupasha joto haraka. d) Vipengele viwili vingi zaidi hewani ni Nitrojeni na Oksijeni. e) Hewa inachukuliwa kuwa mchanganyiko kwa sababu mbili zifuatazo: • Vipengele vyake vinaweza kutenganishwa kwa njia za kimwili, kama vile usafishaji wa sehemu (fractional distillation) wa hewa iliyogandishwa. • Vipengele vyake havijaungana kemikali na kila kimoja huhifadhi sifa zake binafsi. f) Ili kuthibitisha uwepo wa kaboni (IV) oksidi hewani, jaribio linaweza kufanywa kama ifuatavyo: • Weka maji ya chokaa safi (calcium hydroxide solution) kwenye chombo wazi na uyaache wazi hewani. • Baada ya muda, utaona maji ya chokaa yakigeuka mawingu (milky) kutokana na kuundwa kwa calcium carbonate isiyoyeyuka. Hii inathibitisha uwepo wa kaboni (IV) oksidi hewani. g) i) A. Precipitate W: Lead (II) sulfate (PbSO_4) B. Colorless solution X: Magnesium sulfate solution (MgSO_4) That's 2 down. 3 left today — send the next one.
