Chemistry at your fingertips. For those who are scared of formulas

Chemistry is a magical science. Without any exaggeration, magical, because she studies the transformations of some substances into others. Chemistry is considered to be a complex science, difficult for understanding, requiring zealous cramming, although in reality this is not so.
Chemistry is extremely logical. In it, everything happens in full compliance with the laws. If you know the rules, then you will need nothing to be cramped. You need to understand. What chemistry does not forgive is knowledge gaps. With the same physics, the situation is a little different. You can excellently understand the mechanics, completely not knowing the optics. With chemistry, such a number will not pass. Sooner or later, the gap will “come around”, will make itself felt in a completely unexpected situation. It seems to be correct, it seems that during the reaction one substance was supposed to turn out, but it turned out another. As it was sung in one old song: I wanted to make a thunderstorm, but got a goat. An exception? Nothing like this! Chemistry practically does not know exceptions, and those that are available are also logical and explainable
