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.
- 5) Toplam 12,04times 10^23 tane atom içeren CH_(4) gazi normal sartlar altinda kaç litre hacim kaplar?
- STUDY QUE STION Consider naphthalene, C_(10)H_(8) the active ingredient of moth balls. A solution of naphthalene is prepared by mixing 25.0 g of naphthalene with 0750 L of carbon disulfide, CS_(2)(d=1.263g/mL ). Assume that the volume of the solu- tion is the same as that of the solvent after the solution is prepared. (a) What is the mass percent of naphthalene in the solution? (b) What is the concentration of naphthalene in parts per million? (c) What is the density of the solution? (d) What is the molarity of the solution? Answers (e) What is the molality of the solution? (a)2.57% (b) 2.57times 10^4ppm (c) 1.30g/mL
- (d) What is the molarity of the solution? (e) What is the molality of the solution? Answers (a) 2.57% (b) 2.57times 10^4ppm (c) 1.30g/mL (d) 0.260 M (c) 0.206 m
