Question

H3AsO3+Al......?HClO4+Li.......?​

Answer 1

Ответ:  2 HCLO4 + 2 Li = 2 LiCLO4 + H2

2H3AsO3+2Al = 2AlAsO3 + 3H2.

Answer 2

It seems like you're providing a chemical reaction with some missing components indicated by dots. Let's try to fill in the missing information.

1. H3AsO3 + Al → ? + ?

The reaction between H3AsO3 (arsenous acid) and Al (aluminum) is a redox reaction. Aluminum is a reducing agent and can reduce arsenous acid. The balanced equation is:

3 H3AsO3 + 2 Al → 2 H3AsO4 + Al2O3

2. HClO4 + Li → ? + ?

This is a single replacement reaction where lithium (Li) replaces hydrogen (H) in perchloric acid (HClO4). The balanced equation is:

HClO4 + Li → LiClO4 + H2

Here, lithium chloride (LiClO4) and hydrogen gas (H2) are formed.
