Kimyanın Temel Kanunları ve Mol Hesaplamaları

Kimyasal tepkimelerde kütlenin korunumu kanunu her zaman geçerlidir. Bu kanuna göre, tepkimeye giren maddelerin toplam kütlesi, ürünlerin toplam kütlesine eşittir $Mx+y = Ma+b$ . Yani hiçbir atom kaybolmaz veya yok olmaz!

Sabit oranlar kanunu da çok kritik bir kuraldır. Aynı bileşiğin atomları her zaman aynı kütle oranında birleşir. Mesela CaO'da Ca ile O atomları her zaman 5:2 oranında birleşir. Bu kanunu kullanırken formül soruluyorsa veya iki bileşik veriliyorsa çok işimize yarar.

Mol kavramı kimyada en temel hesaplama aracıdır. 1 mol = 6,02×10²³ taneciktir (Avogadro sayısı). Mol ile kütle arasındaki ilişki n = m/MA formülüyle bulunur. Gazlarda ise n = V/22,4 formülünü kullanırız.

Önemli İpucu: Atom kütlesince birleşme oranı sorulduğunda, küçük olan sayı kütle olarak fazla demektir!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
