Question

Li Li2O LiOH LI2CO3 CO3 CO2 CACO3 CAO CA(OH)2 CACI CASO4(перетворення)

Answer 1

4Li + O2 = 2Li2O

Li2O + H2O = 2LiOH

2LiOH + CO2 = Li2CO3 + H2O

Li2CO3 + 2HCl = 2LiCl + H2O + CO2

CaO + CO2 (t)= CaCO3

CaCO3 (t)= CaO + CO2

CaO + H2O = Ca(OH)2

Ca(OH)2 + 2HCl = CaCl2 + 2H2O

CaCl2 + H2SO4 = CaSO4 + 2HCl

Answer 2

It seems like you provided a list of chemical formulas for various compounds. Here's the breakdown of each formula:

1. Li2O: Lithium oxide
2. LiOH: Lithium hydroxide
3. LI2CO3: Lithium carbonate
4. CO3: Carbonate ion (a polyatomic ion consisting of one carbon atom and three oxygen atoms with a 2- charge)
5. CO2: Carbon dioxide
6. CACO3: Calcium carbonate
7. CAO: Calcium oxide (also known as quicklime)
8. CA(OH)2: Calcium hydroxide (also known as slaked lime)
9. CACI: This formula seems incorrect or incomplete. It doesn't represent any known compound.
10. CASO4: Calcium sulfate (without specifying the hydration state)
11. (перетворення): This word means "transformation" in some Slavic languages.
