Write the word and chemical equation for the following statements and balance them:
a) Aluminum metal burns in pure oxygen to produce solid aluminum oxide
b) When solid mercury (II) oxide is heated, it breaks down to form liquid mercury and oxygen gas
c) A solution of ammonium sulfate added to a solution of lead (II) nitrate,forms soluble ammonium nitrate and solid lead (II) sulfate.
Balanced chemical reaction is given below:
4Al + 3O2 = 2Al2O3
2HgO + Heat = 2Hg + O2
(NH4)2SO4 + Hg(NO3)2 = HgSO4 + 2NH4NO3
4Al + 3O2 = 2Al2O3
2HgO + Heat = 2Hg + O2
(NH4)2SO4 + Hg(NO3)2 = HgSO4 + 2NH4NO3
