BALANCING CHEMICAL EQUATIONS
Write the balanced chemical equations of the following chemical reactions:
Equation
2Na + 2H2O = 2NaOH + H2
Reaction
Sodium and water react to form sodium hydroxide and
hydrogen gas.
4Al + 3O2 -------> 2Al2O3
Aluminum and oxygen gas form aluminum oxide.
2KClO3
Potassium chlorate, when heated, decomposes into
potassium chloride and oxygen gas.
------->
2KCl + 3O2
CaO+H2O -------> Ca(OH)2
H3PO4(aq)+3NaOH(aq)→Na3PO4(aq)+3H2O(l)
N2+3H→2NH3
2H3PO4 + 3Zn = Zn3(PO4)2+3H2
H3O{+} + OH{-} = 2H2O
CaCO3------> CaO + CO2
N₂ + O₂ → 2NO
Calcium oxide reacts with water to form calcium hydroxide.
Sodium hydroxide and phosphoric acid react to form
sodium dihydrogen phosphate and water.
Ammonia is formed from the reaction of nitrogen and
hydrogen gasses.
Hydrogen gas is produced as a byproduct in the formation
of zinc phosphate from zinc and phosphoric acid.
Water ionizes itself into a hydroxide anion and a hydronium
cation.
Calcium oxide and carbon dioxide are produced when
calcium carbonate is heated.
Nitrogen and oxygen gasses react to form gaseous nitrous
oxide.
