ISIQEPHU C: UKUFINQA UMBUZO 3 TEXT D Fundisisa lesi siqeshana esingezansi bese usifingqa ngamaphuzu ayi-7. IMIYALELO: 1.    Bhala ngemisho ephelele. Amagama angama-50 kuya kwangama-60. 2.    Imisho yakho mayibe nezinombolo kusukela kweyoku-1 kuya kweye-7. 3.    Bhala iphuzu elilodwa emshweni ngamunye. 4.    Ekugcineni kwamaphuzu wonke owabhalile, bhala inani lamagama owasebenzisile.   TEXT D   ISIKHIYE ESIVULA YONKE IMINYANGO. 1 Imfundo isikhali sokuhlahla endlela ebukeka ingelula kodwa ihambeke.Imfundo uma vula kuvaliwe.Imfundo Ilona kusasa elizoqhakazisa impilo yakho ingabe isafana nakuqala.Imfundo ithulizi lazo zonke izimpi emhlabeni jikelele.Mfunda nawe. 2 Cha bakwethu iqiniso lilihle nje isikole asilulanga kodwa kubiza umuntu ngamunye ukuthi ame isibindi abekezele ngoba ukuze uphumelele empilweni kumele usebenze kanzima.Kulo mhlaba obhubhayo sidinga ukuqinisa kakhulu emfundweni ngoba siyabona izwe esiphila kulo selaphila ngezindlela ezisheshayo bathi lena yemfundo indlela iyathathela. 3  Ngiyayiqakambisa imfundo yesimanje ngoba isibhekelela lonke uhlobo lomuntu.Ngalokhu ngichaza ukuthi uma unguntwana othanda ukupheka noma ophiwe ngase kuphekeni izikole sezafaka izifundo zokupheka.Uma ungumfundi othanda ezemidlalo usungawafeza amaphupho akho okuba ngumdlali oqavile kanjalo uma ungumuntu ophiwe ngase kudwebeni ezikoleni sezikhona izifundo zabadwebayo.Funda mntwana ekhaya balinde wena uzosuka ikati eziko.khohlwa abangani, khohlwa omakhelwane, khohlwa okwasemhlabeni.   RIGHT CLICK ON THE BUTTON BELOW TO OPEN TEXT D IN A NEW TAB      

IMIYALELO   1. Umsebenzi owubhala la makube owakho. Awuvunyelwe ukusebenzisa umsebenzi womunye umuntu.   2. Iphepha lineziqephu ezine: Isiqephu A:  Isifundo sokuqondisisa (20)  Isiqephu B:  Ikhathuni (10) Isiqephu C:  Ukufinqa (10) Isiqephu D:  Izakhiwo zolimi (20)   3. Phendula yonke imibuzo.   4. Bhala ngesizulu.   5. Isikhathi usihlukanise ngalendlela: Imizuzu engu-50 kwisiqephu A Imizuzu engu-20 kwisiqephu B Imizuzu engu-20 kwisiqephu C Imizuzu engu-30 kwisiqephu D  

1.1.6 Khetha impendulo efanele kubakaki. A.    Izingubo zomshado uPhindi uzithunga (zonke izinsuku/ uma kukhona ocela amthungele/ akasazithungi nhlobo). B.    UPhindi wenza isiqiniseko sokuthi (izingubo zakhe zinhle kunezabathengi bakhe/ izingubo zakhe zifana nezabathengi bakhe/ izingubo zabathengi ziba ngcono kunalezo azithungela yena).   (2)

1.30 In this question, all gases can be assumed to behave ideally. A chemist heats a mixture of nitrogen and oxygen gases in a sealed container at a constant temperature until the mixture reaches a dynamic equilibrium containing N2(g), O2(g) and NO(g). N2(g) + O2(g) 2NO(g) The chemist repeats the experiment at the same temperature using the same initial amounts of N2(g) and O2(g), but at a much higher pressure. Which statements about the second experiment at higher pressure are correct?   1 At higher pressure, there are more particles per unit volume. 2 The composition of the equilibrium mixture does not change. 3 There are more collisions per second, so equilibrium is reached faster.  

1.23 Oct-1-ene, CH3(CH2)5CH=CH2, can be thermally cracked.   Which combination of compounds W, X, Y and Z can be obtained by thermally cracking oct-1-ene?   W: CH2=CH2         X: CH3CH=CH2                   Y: CH3CH2CH3            Z: CH2=CHCH=CH2  

1.19 When solid ammonium chloride dissociates at a certain temperature in a 0.500 dm3 container, ammonia and hydrogen chloride are formed.   NH4Cl (s)< == > NH3(g) + HCl (g)   The initial amount of ammonium chloride was 1.00 mol, and when the system had reached equilibrium there was 0.300 mol of ammonium chloride.   What is the numerical value of Kc for this reaction under these conditions?  

1.25 In which reaction is the organic compound oxidised? A CH3CH2CH2CHO + Tollens’ reagent B CH3CH2CH2CHO + LiAlH4 C CH3CH2CH2OH + concentrated H3PO4 D CH3CO2C2H5 + dilute H2SO4
