Kimya Ödev Yardımı
QuetionAI‘nin kimya problemi çözücüsü, temel kimyasal reaksiyonları ve denklemleri kullanıcılar için gerçek zamanlı olarak özetleyebilen ve zayıf bir temele sahip öğrencilerin bile kimyada kolayca uzmanlaşabilmesi için güçlü bir öğrenme sistemine sahip olan bir ortaokul kimya ders aracıdır.
Artık periyodik tablonun temel özellikleri hakkında endişelenmenize gerek yok. Burada her elemente karşılık gelen kimyasal reaksiyonlara ve reaksiyon prensiplerine kolaylıkla ulaşabilirsiniz. Moleküllerin ve atomların orijinal yapısını, görülebilen makroskobik olaylardan çıkarmak, her zaman savunduğumuz bir kimya araştırma tekniğidir.
- Barium chloride reacts with sodium sulfate and forms barium sulfate and sodium chloride. Which of the following statements is correct according to the law of conservation of mass? The total mass of reactants, barium chloride, and sodium sulfate taken is greater than the total mass of the products,barium sulfate, and sodium chloride. The total mass of reactants, barium chloride, and sodium sulfate taken is less than the total mass of the products,barium sulfate and sodium chloride. The total mass of reactants, barium chloride, and sodium sulfate taken is equal to the total mass of the products,barium sulfate and sodium chloride. None of the above.

- According to BP formula is as follows. Ingredients & Quantity (for 50g) Gelatin & 10 mathrm(~g) Glycerol & 35 mathrm(~g) Water & 5 mathrm(~g) Procedure 1. Put the gleatin, glycerol and water in abeaker heat until gelatin is dissolved and melted. 2. Pour into appropriate mould. 3. Let for cooling. 4. Until it is cooled approx (15mins.) 5. Unfold the mould and remove the supposotories. Questions: 1. Formula is for 50 mathrm(~g) of püre base preparation. Each group will prepare 6 mathrm(~g) of supposotories. Calculate the amount of the ingeredients for this amount of preparation. 2. Which type of base it is preparared? Which type of drugs it can be combined with? 3. Eventhough preparation does not contain an active ingredient,s till it can be usefull for using under some conditions. What are these conditions?
