Question 35
Balance the following chemical equations and identify the type of chemical reaction.
(a) Mg(s)+Cl2(g)→MgCl2(s)
(b) HgO(s)Heat−−→Hg(l)+O2(g)
(c) Na(s)+S(s)Fuse−−→Na2S(s)
(d) TiCl4(l)+Mg(s)→Ti(s)+MgCl2(s)
(e) CaO(s)+SiO2(s)→CaSiO3(s)
(f) H2O2(l)UV−−→H2O(l)+O2(g)

Answer 1

(a) Balanced; Combination reaction
(b) 2HgO (s)Heat−−→2Hg (l)+O2(g); Decomposition reaction
(c) 2Na (s)+S (s)Fuse−−→Na2S (s); Combination reaction
(d) TiCl4(l)+2Mg (s)→Ti (s)+2MgCl2(s); Displacement reaction
(e) Balanced; Combination reaction
(f) H2O2(l)UV−−→2H2O (l)+O2(g); Decomposition reaction
