Chemical Reactions

What are four common chemical reactions seen in inorganic chemistry?

Table 31.1: Four common chemical reactions

Red-ox	$2Fe + 6HCl \rightarrow 2FeCl_{3} + 3H_{2}$
	Note: The element that is displaced is reduced (H), the element that does the displacing is oxidized (Fe).
Displacement	$AgNO_{3} + HCl \rightarrow AgCl + HNO_{3}$
Decomposition	$2HgO \rightarrow 2Hg + O_{2}$
Acid-Base	$2NaOH + H_{2}SO_{4} \rightarrow Na_{2}SO_{4}+2H_{2}O$
(or neutralization)
