... (hydrogen) has a mass close to one gram, simplifies the arithmetic in problems with other atoms, especially when we convert between grams and moles. That’s our goal: to calculate a count of particles by measuring their mass on a balance or scale. Counting the particles is important because in chemic ...

chemical kinetics
... Some reactions such as ionic reactions occur very fast, for example, precipitation of silver chloride occurs instantaneously by mixing of aqueous solutions of silver nitrate and sodium chloride. On the other hand, some reactions are very slow, for example, rusting of iron in the presence of air and ...

... 1. The rate law might not have a simple form at all. 2. You might get tired before guessing the right form, and decide that one of the ones you have already done seems to fit the data “okay”, not realizing that another rate law (that you didn’t try) fits much better. If you use this method on a reac ...
