the answer is chemical energy because chemical energy converts into motion energy and motion is kinetic energy
Oxygen is 21% and nitrogen is 78% so combined is 99%
Answer:
1.772 mols
Explanation:
Because hydrogen exists as a diatomic molecule in gaseous state, that's (H2), so then it's molecular mass is 1 ×2= 2g/mol.
we can now calculate for the number of moles, so
n=m/Mr
n=3.544/2
n=1.772mols
