USHAURI MAALUMU WA WANAFUNZI WOTE WA NECTA KIDATO CHA NNE OKTOBA 23 ,2026 IJUMAA---MASOMO CHEMISTRY 1 ( 033 / 1 ) NA HISTORY ( 012 )
Masomo: CHEMISTRY 1 (031/1) asubuhi na HISTORY (012) mchana — Ijumaa, 23 Oktoba 2026
Mwanafunzi, nakutakia kila la heri katika mitihani yako. Lengo lako la kupata A katika Chemistry na History ni zuri sana. Kwa kuwa una muda mfupi wa maandalizi, unahitaji kusoma kwa mpangilio, kufanya mazoezi ya maswali na kukumbuka mambo muhimu badala ya kujaribu kusoma kila kitu bila mpango.
Jambo muhimu: Hakuna mtu anayeweza kuthibitisha mada au maswali yatakayotoka katika mtihani halisi kabla ya mtihani. Nitakupa mada za kipaumbele, aina za maswali ya kujizoeza na mpango wa marudio. Hizi si taarifa za siri za NECTA wala hakikisho kwamba kila mada itatoka.
1. CHEMISTRY 1 — asubuhi
Lengo lako: Kuwa na uwezo wa kueleza kanuni, kuandika milinganyo ya kikemia, kufanya hesabu na kujibu maswali ya majaribio.
Kwa Chemistry, usikariri majibu pekee. Jizoeze pia namna ya kupata jibu na kuonyesha hatua za kufanya hesabu.
A. Mada za kupewa kipaumbele
Mada hizi zinatokana na maudhui ya Chemistry katika muundo wa mtihani wa NECTA.
1. Mole concept na chemical calculations
Relative atomic mass (Ar) na relative molecular mass (Mr).
Kuhesabu idadi ya mole: \(n=\frac{m}{M}\).

Kuhesabu mass, moles na kiasi cha gesi kwa kutumia taarifa zilizotolewa.
2. Acids, bases and salts
Sifa za asidi na besi.

Kurekodi observations na kuandika conclusions.
5. Organic chemistry

Electrolysis na ionic theory.
Extraction of metals.
Air, combustion and rusting.
Water, hardness of water, hydrogen, oxygen, fuels, soil chemistry na pollution.
B. Aina za maswali ya kujiandaa nayo
Haya ni maswali ya mazoezi yaliyotungwa kwa kuzingatia mada husika, si maswali yaliyothibitishwa kuwa yatatoka.
1. Hesabu: Calculate the number of moles in 12 g of carbon if \(A_r(C)=12\).
Jibu: \(n=12/12=1\) mole.
2. Milinganyo: Balance the equation:
Jibu: \(\mathrm{2Mg+O_2\rightarrow 2MgO}\).
3. Acids and bases: Explain three differences between acids and bases.
4. Atomic structure: An atom has atomic number 17 and mass number 35. Find the number of protons, electrons and neutrons.
Jibu: Protons = 17; electrons = 17 kwa atomu isiyo na chaji; neutrons = \(35-17=18\).
5. Electrolysis: Explain what happens when an electrolyte is electrolysed and identify the functions of the anode and cathode.
6. Organic chemistry: Differentiate between alkanes and alkenes, giving their general formulae and examples.
7. Qualitative analysis: Given an unknown solution, describe the test, observation and conclusion used to identify a particular ion.
8. Volumetric analysis: Given titration readings and a balanced equation, calculate the unknown concentration.
C. Mambo ya kukumbuka ili kuongeza alama
Andika formula kabla ya kuanza hesabu.
Onyesha hatua zote za hesabu, si jibu la mwisho tu.
Usisahau units kama g, mol, cm³ na mol/dm³.
Katika maswali ya majaribio, tofautisha observation na inference/conclusion.
Soma swali vizuri: state, define, explain, compare, calculate na describe vinahitaji majibu yenye viwango tofauti vya maelezo.
Tahadhari ya namba ya somo: Muundo rasmi wa NECTA wa 2022 unaorodhesha Chemistry kama 032 na Physics kama 031.
2. HISTORY (012) — mchana
Lengo lako: Kuelewa sababu, matukio, athari na umuhimu wa matukio ya kihistoria. Usikariri majina na miaka pekee; jifunze kueleza kwa nini jambo lilitokea na matokeo yake.
Kwa mujibu wa muundo rasmi wa NECTA, History ina mada 16. Mada za Nationalism and Decolonisation na Changes in Political, Social and Economic Policies in Africa after Independence kila moja zina uzito wa 15% katika jedwali la mgawanyo wa mada.

Kabla ya Chemistry
Pitia formula, milinganyo, hesabu na majaribio. Usianze mada ngumu ambayo hujawahi kuisoma.
Baada ya Chemistry
Pumzika kidogo, kunywa maji na kula chakula kinachokufaa. Kisha pitia muhtasari wa History, hasa sababu, athari na mifano ya matukio.
4. Siri za kuongeza nafasi ya kupata A
Jibu swali lililoulizwa. Ikiwa limeomba sababu sita, toa sababu sita zilizoelezwa, si majina pekee.
Tumia hoja zenye maelezo. Katika History, kila hoja iambatane na ufafanuzi na mfano unaofaa.
Fanya mazoezi kwa muda. Chemistry, jizoeze kufanya hesabu bila kuangalia majibu; History, jizoeze kuandika insha kwa mpangilio.
Pitia makosa yako. Kila swali unalokosea, elewa sababu ya kosa kabla ya kuendelea.
Lala vya kutosha. Usikeshe usiku mzima ukisoma. Akili iliyopumzika husaidia kukumbuka na kufikiri vizuri.
Katika chumba cha mtihani, soma maelekezo yote, gawa muda kulingana na alama, onyesha hatua za hesabu na kagua majibu kabla ya kukabidhi karatasi.
