Answer 1

a, Zn + 2HCl → ZnCl2 + H2↑

b, CuO + H2 → Cu + H2O ( t\(^o\))

c, 2Na + 2H2O → 2NaOH + H2↑

d, Fe + CuSO4 → FeSO4 + Cu↓

đ, C12H22O11 + H2O → C6H12O6 + C6H12O6 ( điều kiện :acid)

( fructozo) ( glucozo)

e, BaCl2 + Na2SO4 → BaSO4↓ + 2NaCl

f, CH4 + 2O2 → CO2 + 2H2O (t\(^o\))

g, CaO + H2O → Ca(OH)2

Answer 2

a) Zn + 2HCl --> ZnCl2 + H2

b) CuO + H2 -to-> Cu + H2O

c) 2Na + 2H2O --> 2NaOH + H2

d) Fe + CuSO4 --> FeSO4 + Cu

đ) C12H22O11 + H2O -axit-> C6H12O6 + C6H12O6

e) BaCl2 + Na2SO4 --> BaSO4 + 2NaCl

f) CH4 + 2O2 -to-> CO2 + 2H2O

g) CaO + H2O --> Ca(OH)2

Answer 3

\(Zn+2HCl\rightarrow ZnCl_2+H_2\uparrow\)

\(CuO+H_2\rightarrow Cu+H_2O\)

\(Na+2H_2O\rightarrow2NaOH+H_2\uparrow\)

\(Fe+CuSO_4\rightarrow FeSO_4+Cu\)

\(C_{12}H_{12}O_{11}+H_2O\rightarrow C_6H_{12}O_6+C_6H_{12}O_6\)(ĐK AXIT)

\(BaCl_2+Na_2SO_4\rightarrow BaSO_4+2NaCl\)

\(CH_4+2O_2\underrightarrow{t^o}2CO_2+2H_2O\)

\(CaO+H_2O\rightarrow Ca\left(OH\right)_2\)

Answer 4

a) Zn + 2HCl → ZnCl₂ + H₂

b) CuO + H₂ \(\underrightarrow{to}\) Cu + H₂O

c) 2Na + 2H₂O → 2NaOH + H₂

d) Fe + CuSO₄ → FeSO₄ + Cu

đ) C₁₂H₂₂O₁₁ + H₂O \(\underrightarrow{axit}\) C₆H₁₂O₆ + C₆H₁₂O₆

e) BaCl₂ + Na₂SO₄ → BaSO₄↓ + 2NaCl

f) CH₄ + 2O₂ \(\underrightarrow{to}\) CO₂ + 2H₂O

g) CaO + H₂O → Ca(OH)₂

Answer 5

a) Zn + 2HCl → ZnCl2 + H2

b) CuO + H2 Cu + H2O

c) 2Na + 2H2O → 2NaOH + H2

d) Fe + CuSO4 → FeSO4 + Cu

đ) C12H22O11 + H2O \(\underrightarrow{axit}\) C6H12O6 + C6H12O6

e) BaCl2 + Na2SO4 → BaSO4↓ + 2NaCl

f) CH4 + 2O2 \(\underrightarrow{to}\) CO2 + 2H2O

g) CaO + H2O → Ca(OH)2
