Question

A) H,SO, + Zn = 6) Na,O + H20 = в) Сисі, + Кон T) CaO + CO, = Срочно

Answer 1

Ответ:

Объяснение:

H2SO4 + Zn = ZnSO4 + H2↑

Na2O + H2O = 2NaOH

CuCl2 + 2KOH = Cu(OH)2↓ + 2KCl

CaO + CO2 = CaCO3

Answer 2

It seems like you're providing chemical equations, but the formatting is a bit unclear. I'll do my best to interpret and balance them for you:

A) H2SO4 + Zn → ZnSO4 + H2 This is the reaction between sulfuric acid (H2SO4) and zinc (Zn) to produce zinc sulfate (ZnSO4) and hydrogen gas (H2).

6. Na2O + H2O → 2 NaOH This is the reaction between sodium oxide (Na2O) and water (H2O) to produce sodium hydroxide (NaOH).

в) C6H6 + O2 → CO2 + H2O This is the combustion reaction of benzene (C6H6) with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O).

T) CaO + CO2 → CaCO3 This is the reaction between calcium oxide (CaO) and carbon dioxide (CO2) to produce calcium carbonate (CaCO3).
