Faahfaahinta casharka

Natiijada casharka

Waxaan sharxi karaa ilaalinta cufka oo aan u qori karaa isla'egyo kiimikaad oo dheeli tiran si aan u muujiyo sida atomada falceliyeyaasha falcelin kiimikaad loo habeeyo si ay u sameeyaan waxsoosaar.

Hordhac

Maanta waxaan ku baranaynaa ilaalinta cufka (conservation of mass) iyo sida loo dheellitiro isla'egyada calaamadaha (balanced symbol equations). Waxaad horey uga yaqaanay fal-celiyeyaasha (reactants) iyo waxsoosaarka (products), laakiin maanta waxaan si qoto dheer u eegaynaa sida atamka loo habeeyo inta lagu jiro falgalka burburka (decomposition reaction). Diyaar u ahow inaad adeegsato aqoontaada qaacidada kiimikaad (chemical formula) si aad u fahamto sida cufku u ilaalsamo.

Muuji qoraalka
The mass of the products in a chemical reaction is the same as the mass of the reactants. Word equations are a simple way of describing chemical reactions. Chemical formulae represent the numbers of each type of atoms in a reactant or product. Chemical equations represent how the atoms in the reactants rearrange to form the products. The arrow in a chemical equation represents the words ‘changes into’.

  1. 1. Falaarta ku taal isla'egta kiimikada (chemical equation) waxay muujinaysaa maxay?

    • waxay la mid tahay
    • ku darid
    • Jawaabta saxda ah:isku beddelasho
    • isku dhufasho

  2. 2. Kee ka mid ah weedhahan ku saabsan cufka (mass) walxaha falgalka (reactants) iyo waxyaabaha soo baxa (products) ee falgalka kiimikaadku waa sax?

    • Cufka walxaha falgalka wuu ka weyn yahay cufka waxyaabaha soo baxa.
    • Cufka walxaha falgalka wuu ka yar yahay cufka waxyaabaha soo baxa.
    • Jawaabta saxda ah:Cufka walxaha falgalka wuxuu la mid yahay cufka waxyaabaha soo baxa.
    • Cufka walxaha falgalka wuxuu noqon karaa mid ka weyn ama ka yar cufka waxyaabaha soo baxa.

  3. 3. Waa maxay isla'egta ereyada (word equation)?

    • Waa hab lagu sharaxo falcelinta iyadoo la isticmaalayo astaamo (symbols).
    • Jawaabta saxda ah:Waa hab lagu sharaxo falcelinta iyadoo la isticmaalayo magacyada kiimikada ee walxaha falceliya iyo kuwa soo baxa.
    • Waa isla'eg astaamo ah oo dheellitiran (balanced symbol equation).
    • Waa nooc ka mid ah qaacidada kiimikada (chemical formula).

  4. 4. Maxay tahay sababta ay tahay in isla'egta calaamadaha (symbol equations) loo dheellitiro?

    • Si loo beddelo aqoonsiga walxaha falgalka (reactants).
    • Si loo muujiyo in maater la abuuray ama la buriyay.
    • Jawaabta saxda ah:Si loo si sax ah u matalo ilaalinta cufka (conservation of mass).
    • Si looga dhigo isla'egta mid aad u adag.
