Question

Balance the following equations. (Use the lowest possiblecoefficients. Include states-of-matter under the given conditionsin your answer.) (a) KNO3(s) -> KNO2(s) +O2(g) (b) La2O3(s) + H2O(l) ->La(OH)3(aq) (c) NCl3(aq) + H2O (l) ->NH3(aq) + HOCl(aq) (d) Mg3N2(s) + HCl(aq) ->MgCl2(aq) + NH4Cl(aq) (e) AgNO3(aq) + K2SO4(aq)-> Ag2SO4(s) + KNO3(aq) (f) Al(OH)3(s) + H2SO4(aq)-> Al2(SO4)3(aq) +H2O(l) (g) CH3NH2(g) + O2(g) ->CO2(g) + H2O(g) + N2(g) Balance the following equations. (Use the lowest possiblecoefficients. Include states-of-matter under the given conditionsin your answer.) (a) KNO3(s) -> KNO2(s) +O2(g) (b) La2O3(s) + H2O(l) ->La(OH)3(aq) (c) NCl3(aq) + H2O (l) ->NH3(aq) + HOCl(aq) (d) Mg3N2(s) + HCl(aq) ->MgCl2(aq) + NH4Cl(aq) (e) AgNO3(aq) + K2SO4(aq)-> Ag2SO4(s) + KNO3(aq) (f) Al(OH)3(s) + H2SO4(aq)-> Al2(SO4)3(aq) +H2O(l) (g) CH3NH2(g) + O2(g) ->CO2(g) + H2O(g) + N2(g)

Explanation / Answer

(a) 2KNO3(s) ---> 2KNO2(s) +O2(g) (b) La2O3(s) + 3H2O(l)---> 2La(OH)3(aq) (c) NCl3(aq) + 3H2O (l) ->NH3(aq) + 3HOCl(aq) (d) Mg3N2(s) + 8HCl(aq) ->3MgCl2(aq) + 2NH4Cl(aq) (e) 2AgNO3(aq) + K2SO4(aq)-> Ag2SO4(s) + 2KNO3(aq) (f) 2Al(OH)3(s) + 3H2SO4(aq)-> Al2(SO4)3(aq) +6H2O(l) (g) 4CH3NH2(g) + 9O2(g)---> 4CO2(g) + 10H2O(g) +2N2(g)
