Question

Na + H₂O →
CuO + H₂O→
SO₃ + H₂O→

Answer 1

\(Na+H_2O\rightarrow NaOH+\dfrac{1}{2}H_2\)

\(CuO+H_2O\rightarrow X\)

\(SO_3+H_2O\rightarrow H_2SO_4\)

Answer 2

$2Na + 2H_2O \to 2NaOH + H_2$
$CuO + H_2O \to$ Không phản ứng

$SO_3 + H_2O \to H_2SO_4$

Answer 3

2Na + 2H₂O → 2NaOH + H\(_2\)
CuO + H₂O→ Ko có pư
SO₃ + H₂O→ H\(_2\)SO\(_4\) 

Answer 4

2Na + H2O --> 2NaOH

CuO + H2O --> Cu(OH)2

SO3 + H2O --> H2SO4
