N h2o = mh20/Mh20
= 8.0g/18g/mol
=0.44 mol
therefore n O = 0.44mol
therefore n H2 = 0.88 mol
m H2 = n H2 * M H2
= 0.88 mol * 2 g/mol
=1.76 g
A chemical reaction is a reaction that changes the molecular structure and is normally irreversible.
The person would look B) in the nucleus.
Hope this helps!
