Hapa kuna majibu yako: TAT 6 : SALTS 1. Fafanua yafuatayo: a) Chumvi ya deliquescent Chumvi ya deliquescent ni chumvi ambayo inanyonya unyevu kutoka hewani na kuyeyuka ndani yake na kutengeneza mmumunyo. b) Chumvi ya hygroscopic Chumvi ya hygroscopic ni chumvi ambayo inanyonya unyevu kutoka hewani lakini haiyeyuki ndani yake. 2. Andika milinganyo ya kikemikali kuonyesha athari ya joto kwenye chumvi zifuatazo: a) Zinc nitrate Step 1: Andika fomula ya zinc nitrate, ambayo ni Zn(NO₃)₂. Step 2: Andika mlinganyo wa kuoza kwa joto. Zinc nitrate huozeka na kutoa zinki oksidi, nitrojeni dioksidi, na oksijeni. 2Zn(NO₃)₂(s) Δ 2ZnO(s) + 4NO₂(g) + O₂(g) b) Sodium hydrogen carbonate Step 1: Andika fomula ya sodium hydrogen carbonate, ambayo ni NaHCO₃. Step 2: Andika mlinganyo wa kuoza kwa joto. Sodium hydrogen carbonate huozeka na kutoa sodium carbonate, maji, na kaboni dioksidi. 2NaHCO₃(s) Δ Na₂CO₃(s) + H₂O(g) + CO₂(g) c) Copper (II) sulphate Step 1: Andika fomula ya copper (II) sulphate. Kwa kawaida, hii inarejelea fomu yenye maji, CuSO₄ · 5H₂O. Step 2: Andika mlinganyo wa kwanza wa kuondoa maji ya fuwele. CuSO₄ · 5H₂O(s) Δ CuSO₄(s) + 5H₂O(g) Step 3: Andika mlinganyo wa kuoza zaidi wa anhydrous copper (II) sulphate kwa joto kali. 2CuSO₄(s) joto kali 2CuO(s) + 2SO₂(g) + O₂(g)

Define the following: a) deliquescent salt b) hygroscopic salt. 2. Write chemical equations to show action of heat on the following salts. a) zinc nitrate b) sodium hydrogen carbonate c) copper (ii) sulphate
