Question

Decide whether a reaction occurs for each of the following. If itdoes, write the balanced molecular equation. Then write the netionic equation.
(a) Al(OH)3 + HNO3 1 2(aq) + 3 4(l)
net ionic equation
5 6(s) + 7 8(aq) 9 10(aq) + 11 12(l)

(b) FeS + HClO4 13 14(aq) +15 16(g)
net ionic equation
17 18(s) +19 20(aq) 21 22(aq) +23 24(g)

Explanation / Answer

Equation Al(OH)3 + 3HNO3 --> Al(NO3)3 + 3H20 net ionic: Al(OH)3(s) + 3H(aq) = Al(aq) +3H20(l)     NO3- is cancels out on both sides Equation: FeS + 2 HClO4 ---> Fe(ClO4)2 + H2S For the net ionic FeS + 2H+ -> Fe2+ + H2S ClO4 cancels out
