MnO2
Example. 2 H2O2(aq)
2 H2O(1) + O2(g)
hydrogen peroxide
Hydrogen peroxide in a water solution decomposes in the presence of manganese(IV)
oxide. As the result of the reaction, liquid water on oxygen gas are generated.
Another example. Mg(s) + CuCl2(aq) → MgCl2(aq) + Cu(s)
Solid magnesium (you can also say "metallic magnesium", since it is a metal in its elementa
form) reacts with copper(II) chloride dissolved in water. The reaction produces solid
copper and aqueous magnesium chloride.
Interpret the following chemical equations (3 points each):
1. 2 Ca(NO3)2(s) → 2 CaO(s) + 4 NO2(g) + O2(g)
2. ZNCI2(aq) + 2 NaOH(aq) → Zn(OH)2(s) + 2
NaCl(aq)
3. Mg(s) + 2 HCI(aq)
MgCl2(aq) + H2(g)
hydrochloric acid
