Question

For each of the following, specify if a reaction does or does not occur when the two reagents are combined, and justify your choice of reaction or no reaction. For each combination where a reaction does occur, write balanced molecular and net ionic equations for that reaction. (NH_4)_2 CO_3 (aq) + MgBr_2 (aq) rightarrow Ni(C_2 H_3 O_2)_2 (aq) + K_3 PO_4 (aq) rightarrow Sr (OH)_2 (aq) + HC_2 H_3 O_2 (aq) rightarrow CuSO_4 (aq) + Co(NO_3)_2 (aq) rightarrow Cs_2 CO_3 (aq) + Hl(aq) rightarrow Sr(OH)_2 (aq) + HBr (aq) rightarrow H_2 SO_4 (aq) + KOH(aq) rightarrow HCl(aq) + H_2NCH_2 CH_2 NH_2 (aq) rightarrow HO_2 CCO_2 H(aq) + NaOH(aq) rightarrow

Explanation / Answer

. For each of the following, specify if a combined, and justify your choice of occur, write balanced molecular and

a. (NH)2CO3(aq) + MgBr2(aq)

(NH4)2CO3(aq) + MgBr2(aq) = (NH4)2Br2 + MgCO3
Reaction type: double replacement

Magnesium carbonate will precipitate, because it is insoluble.

=====================================================

b. Ni(C2H303)2(aq) + K3PO4(aq) —.

2 K3PO4(aq)+ 3 Ni(NO3)2(aq)= 6 KNO3 + Ni3(PO4)2
Reaction type: double replacement

=====================================================

c. Sr(OH)2(aq) + HC2H2O2(aq)

2 HC2H3O2 + Sr(OH)2 = Sr(C2H3O2)2 + 2 H2O
Reaction type: double replacement

==================================================

d. CuSO4(aq) + Co(NO3)2(aq) —•

aqueous solution of cuso4 is acidic in nature

Co(NO3)2; acidic

==========================================

e. Cs2CO3(aq) + Hl(aq) —•

CS2CO3 acid

Hydroiodic acid

========================================

f. Sr(OH)2(aq) + HBr(aq) —.

2 HBr(aq) + Sr(OH)2(aq) = 2 H2O(l) + SrBr2(aq)
Reaction type: double replacement
======================================================

g. H2SO4(aq) + KOH(aq)

H2So4(aq) + 2 KOH(aq) = K2So4(aq) + 2 H2O(l)
Reaction type: double replacement

=================================

h. HCI(aq) + H2NCH2CH2NH2(aq)

HCI(aq) acid

H2NCH2CH2NH2(aq) acid

===================
