Here's the link posted by VIN. Sorry my net is really slow right now, I can hardly upload anything.

Here's my question.

i see

HINT : COMPARABLE TO ALKANES !!! FORMULA OF ALKANES IS  = CnH2N + 2 RIGHT?

and it says 4???

and it says hydride???

so just draw BUTANE and repace the 4 carbons by 4 Germanium atoms !


2. like combustion of alkanes , CO2 + H20, THIS TIME GEO2 + H20
