how would i write the word equation, balance it and identify the following?

Question

1)pentyne(C5H8) burns in oxygen gas to produce carbon dioxide gas and water vapor

2) a solution of lithium phosphate will react with a solution of zinc sulfate to form a precipitated solid of zinc phosphate and a solution of lithium sulfate

3) mercury(II) oxide is heated to release oxygen gas and produce liquid metal




if you only know some...thats ok anything will help
THank YOU!!!

Answer 1

1) C5H8(s) + 7O2(g) --> 5CO2(g) + 4H2O(g)

2) 2Li3PO4(aq) + 3ZnSO4(aq) --> 3Li2(SO4)(aq) + 2Zn2(PO4)3(aq)

3) 2HgO(s) --> O2(g) + 2Hg (l)

Answer 2

C5H8 +7O2(g)---> 5CO2(g) +4H2O

2Li3PO4(aq)+ 3ZnSO4(aq)--->3Li2SO4(aq) +Zn3(PO4)2(s)

2HgO---> O2(g) +2Hg(l)
