Question

Li ->Li2O -> LiCl -> LiCl -> HCl

Answer 1

Li+o2=lio2
lio2+2hcl=2licl+h20

licl +h2so4к=hcl + lihso4

Answer 2

The given sequence of chemical reactions appears to involve lithium (Li), lithium oxide (Li2O), and hydrogen chloride (HCl). Here's a brief explanation of each step:

1. Li -> Li2O: This is a combustion reaction, where lithium metal (Li) reacts with oxygen (O2) in the air to form lithium oxide (Li2O).

2. Li2O -> LiCl: Lithium oxide (Li2O) reacts with hydrochloric acid (HCl) to form lithium chloride (LiCl) and water (H2O).

3. LiCl -> LiCl: This step doesn't involve a chemical reaction but rather a change in the physical state of the substance. LiCl is a salt that can exist as a solid or a liquid, depending on its temperature and pressure.

4. LiCl -> HCl: Finally, when lithium chloride (LiCl) is heated strongly, it decomposes into lithium chloride gas (LiCl) and hydrogen chloride gas (HCl).

Overall, this sequence of reactions involves the transformation of lithium metal into lithium chloride and hydrogen chloride gases.
