Decomposition Reactions to Memorize

Flashcards covering key decomposition reactions, equations, and general rules.

Decomposition of $H_2CO_{3(aq)}$

$$H_2CO_{3(aq)} \rightarrow H_2O_{(l)} + CO_{2(g)}$$

Decomposition of $H_2O_{2(aq)}$

$$2 H_2O_{2(aq)} \rightarrow 2 H_2O_{(l)} + O_{2(g)}$$

Decomposition of $NaHCO_3$

$$2 NaHCO_3 \rightarrow Na_2CO_3 + H_2O + CO_2$$

Decomposition of $NH_4OH$

$$NH_4OH \rightleftharpoons NH_3 + H_2O$$

Behavior of $NH_{3(aq)}$ in Double Replacement Reactions

$NH_{3(aq)}$ in a double replacement reaction behaves like $NH_4OH$

Hydrate Decomposition

$$\text{Hydrate} \rightarrow \text{Anhydrate} + \text{Water}$$

Metal Hydroxide Decomposition

$\text{Metal hydroxide} \rightarrow \text{Metal oxide} + \text{Water}$ (in reverse: synthesis)

Oxyacid Decomposition

$\text{Oxyacid} \rightarrow \text{Nonmetal oxide} + \text{Water}$ (in reverse: synthesis)
