Question

Balance the following equations, and indicate whether they arecombustion, combination, or decomposition reactions. (Use thelowest possible coefficients. Include states-of-matter under thegiven conditions in your answer.) (a) C3H6(g) + O2(g) ->CO2(g) + H2O(l)  combustion,combination or decomposition (b) NH4NO3(s) -> N2O(g) +H2O(l)    combustion, combination ordecomposition (c) C5H6O(l) + O2(g) ->CO2(g) + H2O(l)    combustion,combination or decomposition (d) N2(g) + H2(g) ->NH3(g)    combustion, combination ordecomposition (e) K2O(s) + H2O(l) ->KOH(aq)   combusiton, combination or decomposition Balance the following equations, and indicate whether they arecombustion, combination, or decomposition reactions.

(a) C3H6(g) + O2(g) ->CO2(g) + H2O(l)  combustion,combination or decomposition (b) NH4NO3(s) -> N2O(g) +H2O(l)    combustion, combination ordecomposition (c) C5H6O(l) + O2(g) ->CO2(g) + H2O(l)    combustion,combination or decomposition (d) N2(g) + H2(g) ->NH3(g)    combustion, combination ordecomposition (e) K2O(s) + H2O(l) ->KOH(aq)   combusiton, combination or decomposition

Explanation / Answer

(a) 2C3H6(g) + 9O2(g) ->6CO2(g) + 6H2O(l) ----- combustion (b) NH4NO3(s) -> N2O(g) +2H2O(l)    ---- decomposition (c) C5H6O(l) + 6O2(g) ->5CO2(g) + 3H2O(l)   ----combustion (d) N2(g) + 3H2(g) ->2NH3(g)    ----- combination (e) K2O(s) + H2O(l) ->2KOH(aq) combination
