Chemical Reactions
-
Welding Torch: Acetylene gas (dicarbon dihydride) and oxygen gas combine to form carbon dioxide and water vapor.
-
Word Equation: dicarbon dihydride + oxygen gas → carbon dioxide + water
-
Skeleton Equation: C2H2(g) + O2(g) → CO2(g) + H2O(g)
-
Zinc and Silver Nitrate: Zinc metal added to silver nitrate solution produces zinc nitrate solution and silver.
-
Word Equation: zinc + silver nitrate → zinc nitrate + silver
-
Skeleton Equation: Zn(s) + AgNO3(aq) → Zn(NO3)2(aq) + Ag(s)
-
Zinc Carbonate Decomposition: Heating solid zinc carbonate produces solid zinc oxide and carbon dioxide gas.
-
Word Equation: zinc carbonate → zinc oxide + carbon dioxide
-
Skeleton Equation: ZnCO3(s) → ZnO(s) + CO2(g)
-
Nitrogen and Oxygen Reaction: Nitrogen and oxygen gases react to form nitrogen dioxide.
-
Word Equation: nitrogen + oxygen → nitrogen dioxide
-
Skeleton Equation: N2(g) + O2(g) → N2O2(g)
-
Potassium Hydroxide and Phosphoric Acid: Potassium hydroxide solution and phosphoric acid react to produce water and potassium phosphate solution.
-
Word Equation: potassium hydroxide + phosphoric acid → water + potassium phosphate
-
Skeleton Equation: KOH(aq) + H3PO4(aq) → H2O(l) + K3PO4(aq)
-
Methane Combustion: Methane (natural gas) reacts with oxygen to form carbon dioxide and water vapor.
-
Word Equation: methane + oxygen → carbon dioxide + water
-
Skeleton Equation: CH4(g) + O2(g) → CO2(g) + H2O(g)
