Question

metal + H2O -> metal oxide + H2(g)

but
Na+ H20 gives NaOH+H2 why
can we write
Na + H20 ->Na2O +H2 ????​

Answer 1

Answer:

hey mate you should prefer your book again as metal+water gives or prepares base

Explanation:

Metal + water-> base+H2

Therefore whenever any reaction of metal with water took place it gives base+H2

so Na+H2o->Naoh(base)+H2

another reaction for this types of equations is

Mg+H2o->Mg(oh2)+H2

Hope it helps. mark it brainliest

Answer 2

Answer:

metal + h2o -> metalic oxide that is basic in nature + h2

Explanation:

when naoh reacts with water it forms basic oxide which is naoh.

a concentrated soln of sodium oxide in water will have ph 14

na2o + h2o=> naoh

na2o readily dissoves in wate to form naoh, and so it is actually anhydride of latter. its chemically very similar to its hydrate, naoh, which is typical alkali.
