Question
62. Complete and balance the equation for each example in which a double- displacement reaction will occur. If no reaction will occur write the words "No Reaction" on the right side of the equation. a)HF + KOH-> b) AgNO, + KCI-> c) KOH + ZnCl,-> d) NH,CI+ Ca(NO)2 - 63. Identify four elements that can form more than one cation. 64. Complete and balance the equation for each example in which a single- displacement reaction will occur. If no reaction will occur write the words "No Reaction" on the right side of the equation. Use this activity series: b) F, LiBr- c) Cl, + KI- d) I, + NaCI ->Explanation / Answer
a. HF (aq) + KOH(aq) -------------> KF(aq) + H2O(l)
b. AgNO3 (aq) + KCl(aq) --------------> AgCl(s) + KNO3(aq)
c. 2KOH(aq) + ZnCl2(aq) -------------> Zn(OH)2(s) + 2KCl(aq)
d.2NH4Cl(aq) + Ca(NO3)2(aq) --------> CaCl2(aq) + 2NH4NO3(aq)
63. Fe^2+ , Fe^3+
Mn^2+, Mn^4+ , Mn^+7
Cr^+ , Cr^+6, Cr^3+
Co^2+ , Co^3+
64.
a. Br2 + KCl(aq) -------------------> no reaction
b. F2 + 2LiBr ----------------> 2LiF + Br2
c. Cl2 + 2KI -----------------> 2KCl + I2
d. I2 + NaCl --------------> no reaction
