yuqorida berilgan testlardan qay birining yechimi siz uchun muhimπŸ“
πŸ“Šmayli 100 demayman, 50 ta ovoz yig'sagina yechim beraman, agarda 100 ta ovoz to'plab qolsa, bonus 2 ta masalani ham yechimini beraman, ungacha boshqa post joylaymanπŸ™‚

πŸ‘†bu lab.tajribasidan maqsad 2 ta bo'lgan:
❓ Li eng avvalo H2O bn k.reaksiya beradimi yoki HNO3 bn?
❓ Li kons.HNO3 bn k.reaksiyasida qanday gaz ajraladi?

βœ”οΈ tajribadan ma'lum bo'ldiki Li avvalo HNO3 bn k.reaksiya beradi (unum va ulush jihatdan). Demak, Li ning HNO3 bn k.reaksiya tezligi Li ning H2O bn k.reaksiya tezligidan ancha yuqori.
βœ”οΈ Li metall bo'lakchasi tashlanganda och-qo'ng'ir rangli gaz(lar) ajraldi. Sof NO2 gaz rangi (qizg'ish) qo'ng'ir rang. Li kuchli solvatlanish hususiyatiga ega, shu sababli katta energiya ajrlalishi hisobiga suv molekulalarini ham bug'latadi. Natijada, NO2 va suv bug'i gazlari aralashmasi och-qo'ng'ir rang hosil qilmoqda. Eritmada HNO3 tugagach Li metall bo'lakchasining eritma sirtida suv bn k.reaksiyasi kuzatildi, ya'ni ajralgan gaz H2 ligi sabab ko'rinmadi.

πŸŸ₯kimyoviy reaksiya tenglamalarini tuzib qo'yamiz:
Li + 2HNO3(k) = LiNO3 + NO2 + H2O
2Li + 2H2O = 2LiOH + H2
