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.

Exercise Aluminum Hydroxide (Al(OH)_(3)) is used as an antiacid in some pharmaceutical formulations. It reacts with a typical acid HCl according to the equation: Al(OH)_(3)(s)+3HCl(aq)arrow AlCl_(3)((aq)+3H_(2)O(l) How many grams of HCl are need to neutralize 5.00 g HCl? (MAl(OH)_(3)=78.00g/mol,M_(CO)=36.5g/mol

Exercise Here's a balanced chemical equation for a reaction that occurs in the body to metabolize glucose: C_(6)H_(12)O_(6)+6O_(2)arrow 6CO_(2)+6H_(2)O How many grams are needed to produce 100 g carbon dioxide? (M_(cose)=44.01g/molMMCC_(6)H_(12)O_(6))=180.16g/mol)

Solution The conversion steps are grams of H_(2)arrow moles of H_(2)arrow moles of L_(1)arrow grams c Combining these steps into one equation, we write 9.89gH_(2)times (1molH_(2))/(2.016gH_(2))times (2molH_(2))/(1molH_(2))times (6.941gLi)/(1molH_(2))=68.1gLi Check There are roughly 5 moles of H_(2) in 9.89 g H_(2) so we need 10 moles of Li. From the approximate molar mass of Li (7 g), does the answer seem reasonable?

Exercise During the daytime, carbon dioxide (CO_(2)) reacts with water to form glucose (C_(8)H_(12)O_(6)) and oxygen gas (O_(2)) in the leaves of the plants. The produced glucose is used as the source of energy for plants. Write a balanced equation for this reaction.

Exercise PVC is used to make blister packs , which are widely used for packaging pharmaceuticals. It is produced from vinyl chloride. Vinyl chloride is composed of C, H and Cl. Mass percentages of C and H are 38.43% and 4.84% , respectively. Determine the empirical formula of vinyl chloride. moss
