Complete the following reactions need answers?

i) P + [H]

ii) O2 + [H]

iii) LiH + H2O

iv) CaC2 +H2O

v) NaH + H2O

vi) CaH2 H2O

this reaction will produce phosphine

P+H>PH

this reaction will produce water

O2+H>H2O

this reaction will produce lithium hydroxide and hydrogen gas

LiH+H2O>LiOH+H2

this reaction will produce calcium hydroxide and acetylene gas

CaC2+H2O>Ca(OH)2+C2H2

this reaction will produce sodium hydroxide and hydrogen gas

NaH+H2O>NaOH+H2

this type of reaction will produce calcium hydroxide and hydrogen gas

CaH2+H2O>CaOH+H2

I hope this helps

The formula is (nh4)2co3

Hope you find the answer
