Question

I need help on how to do these balancing equations. If you could show me by breaking down the steps, that would be great. I am struggling big time with this specific chemistry problems.

Predict the missing products for each of the following and then balance the resulting equations.
Please include correct physical states. Identify the type of chemical reaction as combination (C),
decomposition (D), single replacement (SR), double replacement (DR), combustion (B), or acid
base neutralization (N). Write NR if no reaction occurs.
a. ____ type ____ C6H6(l) + ____ O2(g) → _____________________________________
b. ____ type ____ HBr(aq) + ____ Zn(s) → _____________________________________
c. ____ type ____KBr(aq) + MgSO4(aq) → _____________________________________
d. ____ type ____ LiOH(aq) + ____ H2CO3(aq) → ________________________________
e. ____ type ____ O2 (g) + ____ C7H16 (l) → ____________________________________
f. ____ type ____ Li2SO4(aq) + ____ SrCl2(aq) → ________________________________
g. ____ type ____ Al(s) + ____ CuCl2(aq) → ___________________________________
h. ____ type ____ Mg(s) + ____ AgNO3(aq) → ___________________________________
i. ____ type ____ AlN(s) → ____ Al(s) + ____N2(g) (just balance this one)
j. ____ type ____ Mg(s) + ____ P4(s) → ____ Mg3P2(s) (just balance this one)
k. ____type ____NH3(g) → ____N2(g) + ____H2(g) (just balance this one)
l. ____type ____HCl(aq) + Ca(OH)2(aq) → ___________________________________
m. _____type ____NaCl(aq) + ____Pb(NO3)2(aq) → ______________________________

Answer 1

a) 2C6H6(l)+15O2(g) →12CO2(g)+6H2O(g) Combustion reaction

b) 2HBr(aq) + Zn(s) → ZnBr2(s) + H2(g) Double replacement

c) 2KBr(aq) + MgSO4(aq) → MgBr2 (s) + K2SO4 (aq) Double replacement

d) 2LiOH(aq) + H2CO3(aq) → Li2CO3(aq) + 2H2O(l) Double replacement

e) 35O2 (g) + 5C7H16 (l) → 35CO2(g) + 4H2O(g) Single replacement

f) Li2SO4(aq) + SrCl2(aq) → SrSO4(s) + 2 LiCl(aq) Double replacement

g) 2Al(s) + 3CuCl2(aq) → 2AlCl3(aq) + 3Cu(s) Single replacement

h) Mg(s) + 2 AgNO3(aq) → Mg(NO3)2(aq) + 2 Ag(s) Single replacement

i) 2AlN(s) → 2Al(s) + N2(g) Decomposition reaction

j) 6Mg(s) + P4(s) → 2Mg3P2(s) Combination reaction

k) 2NH3(g) → N2(g) + 3H2(g) Decomposition reaction

l) 2HCl(aq) + Ca(OH)2(aq) → CaCl2 (aq) + 2H2O(l) Neutralization reaction

m) 2NaCl(aq) +Pb(NO3)2(aq) → PbCl2(s) + 2NaNO3 (aq) Double replacement
