Question

8, Viết PTHH của H2O với các chất: CaO, BaO, Na2O, K2O, P2O5, SO3

Answer 1

(1) \(CaO+H_2O\xrightarrow[]{}Ca\left(OH\right)_2\)

(2) \(BaO+H_2O\xrightarrow[]{}Ba\left(OH\right)_2\)

(3) \(Na_2O+H_2O\xrightarrow[]{}2NaOH\)

(4) \(K_2O+H_2O\xrightarrow[]{}2KOH\)

(5) \(P_2O_5+3H_2O\xrightarrow[]{}2H_3PO_4\)

(6) \(SO_3+H_2O\xrightarrow[]{}H_2SO_4\)

Answer 2

CaO + H2O -> Ca(OH)2

BaO + H2O -> Ba(OH)2

Na2O + H2O -> 2NaOH

K2O + H2O -> 2KOH

P2O5 + 3H2O -> 2H3PO4

SO3 + H2O -> H2SO4

Answer 3

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

\(BaO+H_2O\rightarrow Ba\left(OH\right)_2\)

\(Na_2O+H_2O\rightarrow2NaOH\)

\(K_2O+H_2O\rightarrow2KOH\)

\(P_2O_5+3H_2O\rightarrow2H_3PO_4\)

\(SO_3+H_2O\rightarrow H_2SO_4\)
