Question

Please i need urgent help solve this​

Answer 1

Explanation:

(a) Mg(s) + Cl2(g) → MgCl2(s) 

This type of reaction is called a combination reaction or a synthesis reaction.

(b) 2HgOis) — (Heat) → 2 Hg(I) + O2(g) 

This is an example of thermal decomposition reaction.

(c) 2Na(s) + S(s) — (Fuse) → Na2S(s) 

This is an example of a Combination reaction.

(d) TiCI4 (1) + Mg(s) → Ti(s) + 2MgCl2 (s) 

This reaction falls under the category of Displacement reactions

(e) Cao(s) + SIO2(s) + CaSIO3(s) 

This is a synthesis reaction.

(f) 2H2O2 (I) — UV → 2H2O(I) + O2 (g) 

This is a decomposition reaction.

PLEASE MARK ME AS BRAINLIST

Answer 2

1. Mg + Cl2 → MgCl2

2. 2HgO → 2Hg + O2

3. 16 Na + S8 → 8Na2S

4. TiCl4 + 2Mg → Ti + 2MgCl2

5. CaO + SiO2 → CaSiO3

6. 2H2O2 → 2H2O + O2
