again ! why not THE hydrogen ?
I think that the English sentence should be "What is the effect of the hydrogen on this object?"
Can someone explain why there's no "the"?
Pe dirijabilul acea?
if you want to use an article then you should use: what's the hydrogen's effect on this object.
Sadly this answer is not accepted. :-(
Otherwise you can still argue if it is a general statement or not.
Second time the same problem
