Explanation / Answer

Q20

balanced formula unit of Sodium hydride + water...

NaH + H2O = H2 + NaOH

for balance:

NaH + H2O = H2 + NaOH

add = 1+1+1+1 = 4

four, choose D

Q2

Oxygen was discoveredn when..

via decomposition of mercury oxide

Q22

the density of O3 is much less than that of O2, therefore it goes to the top
