• Never true

Multiple Choice

Select the correct balanced equation for this single replacement reaction in aqueous solution.

Fe(s) + Pb(NO₃)₂(aq) -->

• 2Fe(s) + Pb(NO₃)₂(aq) --> Pb(s) + 2FeNO₃(aq)

• Fe(s) + Pb(NO₃)₂(aq) --> Fe(s) + Pb(NO₃)₂(aq)

• No reaction

Multiple Choice

Select the correct balanced equation for this single replacement reaction in aqueous solution. (Hint: That is Chlorine by itself, not Carbon bonded to Iodine)

Cl₂(aq) + NaI(aq) -->

• Cl₂(aq) + 2NaI(aq) --> I₂(aq) + 2NaCl(aq)

• Cl₂(aq) + NaI(aq) --> I₂(aq) + NaCl(aq)

• No reaction

Multiple Choice

Select the correct balanced equation for this single replacement reaction in aqueous solution. (Hint: It is best to think of H₂O as HOH in order to see the single replacement reaction better)

Ca(s) + H₂O(l) -->

• Ca(s) + 2H₂O(l) --> 4H(g) + Ca(OH)₂(aq)

• Ca(s) + H₂O(l) --> H₂(g) + CaO(aq)
