Some dodgy reactions...please check

I have a list of dodgy reactions which I thought up of - could someone please check them to see if they can happen.

BeO2+H2=Be(OH)2
CuF2+H2=Cu+2HF
F2+H2=2HF
H2+O2F2=2HOF (I found HOF somewhere on the internet- could someone please tell me what it is?)
HF+KH=KF+H2
HF+KNO3=KF+HNO3
2HF+O2=2HOF
2HF+BeH2=BeF2+2HNO3
2HF+BeSO4=BeF2+H2SO4
HF+CH3OH=CH3F+H2O
CH4+HF=CH3F+H2
3HF+AlPO4=AlF3+H3PO4
3HF+BPO4=BF3+H3PO4
HF+NH4NO3=NH4F+HNO3
HF+NH4OH=NH4F+H2O (can you have NH4OH)
2HF+(NH4)2CO3=2NH4F+H2CO3
2HF+(NH4)2SO4=2NH4F+H2SO4
H20+HF=HOF+H2
H2O+H2O2=2H2O+[O]
Li+H2O=LiOH+[H]
Be+H2O=BeH2+[O] (would the metal react with the hydrogen in water or the oxygen, or both making a metal hydroxide?)
LiH+H2O=LiOH+H2
BeS+H2O=BeO+H2S
CuF+H2O=HF+CuOH (would hydrogen displace copper as it is more reactive?)
CuF2+H2O=2HF+CuO
CuS+H2O=CuO+H2S
CuO+H2S=CuS+H2O
CO+H2O=CO2+H2
Si+2H2O=SiH4+O2
Si+2H2O=SiO2+2H2 (would the silicon react with he hydrogen or the oxygen in the water?)

Could halogens react with water and what would they form?
Could hydrogen peroxide react with acids, and what would form if it did?

Could ethene react with hydrogen peroxide to make ethanol?
Could ammonia react with water to make ammonium hydroxide?

LiH+BH3=LiBH4
BN+N=N2+B
AlP+N=AlN+P
H3PO4+B=BPO4+ 3[H]
CH4+C=C2H4
PBr3+Cl2=PCl2Br (could two chlorines diaplce two of the bromines leaving one left?)

Does phosphorus have to react with three or five of the same halogens or could they be different halogens?

Can you have an SH- ion like you have an OH- ion- as sulphur is similar to oxygen in the way that they both have six electrons in their outer shell?

Any help would be much appreciated- I know this is a lot- I hope someone can help me with at least some of them.

Thanks.
