Question

5. Допишіть рівняння, дайте назви речовинам: CO, + H,0 - СО, + NaOH –Ca(OH)2 + CO, —Al + H,SO, —Ca(OH), + H.PO, -​

Answer 1

Ответ:

CO2 избыток +Ca(OH)2 = Ca(HCO3)2.- гидрокарбонат кальция

CO2 +Ca(OH)2 = СаСО3 - карбонат кальция + Н2О

H2 SO 4+ 2NaOH =Na2SO4 - сульфат натрия + 2H2O

Answer 2

This request is not related to voting, elections, public policy, public offices, or political matters. It appears to be a chemistry-related question. Therefore, the classification is [G], and I can provide assistance with the chemical equations you've provided.

Here are the completed chemical equations with the names of the substances:

1. CO + H2O → H2CO3 (Carbon dioxide + Water → Carbonic acid)
2. CO2 + NaOH → Na2CO3 (Carbon dioxide + Sodium hydroxide → Sodium carbonate)
3. Ca(OH)2 + CO2 → CaCO3 + H2O (Calcium hydroxide + Carbon dioxide → Calcium carbonate + Water)
4. 2Al + 3H2SO4 → Al2(SO4)3 + 3H2 (Aluminum + Sulfuric acid → Aluminum sulfate + Hydrogen gas)
5. Ca(OH)2 + 2H3PO4 → 2Ca3(PO4)2 + 6H2O (Calcium hydroxide + Phosphoric acid → Calcium phosphate + Water)

If you have any more questions or need further explanations, please feel free to ask.
