Question

Balance the following chemical equations and identify the type of chemical reaction.
(a) Mg(s) + Cl2(g) ⎯→MgCl2(s)
(b) HgO(s) ⎯⎯He⎯at⎯→Hg(l) + O2(g)
(c) Na(s) + S(s) ⎯⎯Fu⎯se⎯→Na2S(s)
(d) TiCl4(l) + Mg(s) ⎯→Ti(s) + MgCl2(s)
(e) CaO(s) + SiO2(s) ⎯→CaSiO3(s)
(f) H2O2(l) ⎯⎯U ⎯V⎯→H2O(l) + O2(g)

Answer 1

1. The balanced chemical equations and there type are as follows:

(a) Mg(s) + Cl_​2(g) $\to$ MgCl₂(s) - Combination Reaction

(b) 2 HgO(s) $\stackrel{∆}{\to }$ 2 Hg(l) + O₂ (g) - Decomposition Reaction

(c) 2 Na(s) + S (s) $\stackrel{fuse}{\to }$ Na₂S (s) - Combination Reaction

(d) TiCl₄(l) + 2 Mg(s) $\to$ 2 MgCl₂(s) + Ti(s) - Displacement Reaction

(e) CaO (s) + SiO₂ (s) $\to$ CaSiO₃(s) - Combination Reaction

(f) 2 H₂O₂(l) $\to$ 2 H₂O(l) + O₂ (g) - Decomposition Reaction
