If your child was born on Christmas, you may hear complaints about fewer birthday presents than other kids and more holiday hoo-ha to contend with. (Both most definitely first-world problems.). As it turns out, Christmas birthdays are not only unfortunate -- they're also almost uniquely uncommon. In fact, December 25 is the least common birthday out of all the days of the year save the one that doesn't even occur annually -- February 29.
In a decomposition reaction a compound is broken into smaller chemical species. AB â A + B. The electrolysis of water into oxygen and hydrogen gas is an example of a decomposition reaction : 2 H 2 O â 2 H 2 + O 2. Another example is the decomposition of potassium chloride into potassium and chlorine gas.
A decomposition reaction is also known as analysis reaction which is one of the most common chemical reactions out of all reactions. These reactions involve the decomposition or cleavage of reactant molecules to form small product molecules.
