Which equation represents a decomposition reaction?
O 4P +502 → 2P205
O H2SO4 + 2NaOH → Na2SO4 + 2H2O
O 2C8H18 + 2502 → 16CO2 + 18H2O
O 6NaNO3 → 6NaNO2 + 302

Respuesta :

the fourth reaction describe a decomposition reaction (NaNO3 decomposed to become NaNO2 and O2)

first and third reaction are considered combustion reaction (reacting with oxygen)

second reaction is acid-base reaction
