Chemical Reactions Flashcards
Neutralization
Acid + alkali = salt + water
HCI —>
H+ + Cl-
H2SO4 —>
2H+ + SO42-
HNO3 —>
H+ + NO3-
H3PO4 —>
3H+ + PO43-
Reaction between acid and metal carbonate (or metal Hydrogencarbonate)
Acid + metal carbonate > salt + carbon dioxide + water
Acid + metal Hydrogencarbonate > salt + carbon dioxide + water
H+ + HCO3- >
CO2 + H2O
2H+ + CO32-
CO2 + H2O
Reaction between metal and water
Metal (Group I or II) + water > metal hydroxide + hydrogen
Reaction between metal and acid
Metal + acid > salt + hydrogen
Reaction between metal and oxygen
Metal + oxygen > metal oxide
Reaction between reactive metal with nitrogen
Reactive metal + nitrogen > metal nitride
Reaction between metal and sulphur
Metal + sulphur > metal sulphide
Carbon reduction
Metal oxide + carbon > metal + carbon dioxide
