Question

Balance the following chemical reactions and then classify them as either combination (C), decomposition(D), single replacement (SR) or double replacement (DR)...

a. ___Fe2O3(s)+___H2O(l) produces ___Fe(OH)3   either combination (C), decomposition(D), single replacement (SR) or double replacement (DR)

b. ___BaCl2(aq)+___Na2SO4(aq) produces ___BaSO4(s)+ ___NaCl(aq)  either combination (C), decomposition(D), single replacement (SR) or double replacement (DR)

c. ___CuCl2(aq)+___Al(s) produces ___AlCl3(aq)+___Cu(s)    either combination (C), decomposition(D), single replacement (SR) or double replacement (DR)

d. ___(NH4)2CO3(s) produces ___NH3(g)+___CO2(g)+___H2O(g)    either combination (C), decomposition(D), single replacement (SR) or double replacement (DR)

Explanation / Answer

a. 1Fe2O3(s)+3H2O(l) produces 2Fe(OH)3    combination (C)

b. BaCl2(aq)+Na2SO4(aq) produces BaSO4(s)+ 2NaCl(aq) double replacement (DR)

c. 3CuCl2(aq)+2Al(s) produces 2AlCl3(aq)+Cu(s)    single replacement (SR)

d. (NH4)2CO3(s) produces 2NH3(g)+CO2(g)+H2O(g)     decomposition(D)
