Set up the chemical equation and balance for each (please write out ):
1) tin (4) phosphate + sulfuric acid = ?
2) lead (4) sulfide + hydrocyamic acid = ?
3) ammonium phosphite + dichromic acid = ?
4) mercury (1) hypoiodite + permanganic acid = ?
5) copper (1) carbonate + hydrosulfuric acid = ?
Solution
Chemical equations,
1) Sn3(PO4)4(s) + 6H2SO4(aq) --> 3Sn(SO4)2(aq) + 4H3PO4(aq)
2) PbS2(s) + 4HCN --> Pb(CN)4(aq) + 2H2S(aq)
3) 2(NH4)3PO3(aq) + 3H2Cr2O7(aq) --> 3(NH4)2Cr2O7(aq) + 2H3PO3(aq)
4) Hg(IO)2(s) + 2HMnO4(aq) --> Hg(MnO4)2(aq) + 2HIO(aq)
5) Cu2CO3(s) + H2S(aq) --> Cu2S(s) + H2O(l) + CO2(g)
.
