Faahfaahinta casharka

Natiijada casharka

Waxaan sawiri karaa jaantusyada walxaha ee falceliyeyaasha iyo badeecadaha si aan u muujiyo sida ay u habaynayaan falcelinta kiimikada.

Hordhac

Soo dhawoow darsiga maanta. Darsigani wuxuu ku barayaa sida loo sawiro jaantusyada walxaha ee fal-celiyeyaasha (reactants) iyo wax-soo-saarka (products), iyo sida atamka loogu habeeyo falgal (reaction) kiimiko. Waa inaad hore u taqaanid atamka, curiyeyaasha (elements), iyo xeryahooda (compounds) si aad u fahantid mawduucan.

Muuji qoraalka
Reactants are the chemicals that react in a chemical reaction. Products are the chemicals that are formed in a chemical reaction. The products and reactants in a chemical reaction contain exactly the same atoms. The atoms in the products of a chemical reaction are bonded differently to the same atoms in the reactants.

  1. 1. Marka falgal kiimiko (chemical reaction) dhaco, maxaa ku dhaca atamka (atoms)?

    • Atam cusub ayaa la abuuraa.
    • Qaar ka mid ah atamka waa la baabbi'iyaa.
    • Jawaabta saxda ah:Waa la dib-u-habaynayaa.

    • Waa yaraadaa.
    • Jawaabta saxda ah:Waa isku mid ahaanaysaa.
    • Macluumaad ku filan ma jiro, marka lama go'aamin karo.
    • Xaalado kala duwan oo falcelinta ah waxay keeni karaan jawaabo kala duwan.

  5. 5. Isla'egta 2Na + Cl₂ → 2NaCl, waa maxay saamiga ugu fudud ee atamka sodium (Na) ilaa atamka chlorine (Cl) ee walxaha falgalka (reactants)?

    • 2:1
    • 1:2
    • 2:2
    • 3:1
