C.Cadmium wire is put into a silver fluoride solution. Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if there is no reaction.
D.Magnesium is added to a mercury(II) sulfate solution. Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if no reaction occurs.
E.Mercury is added to a magnesium sulfate solution. Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if there is no reaction
Explanation / Answer
A.Ca(s) + 2 CuNO3 (aq) --------->Ca (NO3)2 (aq) + 2 Cu(s)
Displacement reaction- Ca displaces Cu from CuNO3 solution.
B. Chlorine is heated with oxygen to form dichlorine monoxide gas.
2Cl2 (g)+ O2 (g)---------->2 Cl2O (g)
C. Cd(s) + 2 AgF (aq) ------- CdF2 + 2 Ag(s)
Displacement reaction- Cd displaces Ag from AgF solution
D. Mg(s) + HgSO4 (aq) ------> MgSO4(s) + Hg(l)
E. Hg(s) + MgSO4 (s)--------> no reaction
Hg does not replace Mg (low in activity series)
