Answer:
The new volume of the gas decreased in to 0.329llL
Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O) atoms. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds.
Answer:
1.23 moles
Explanation:
Ideal gas law
PV = n RT R = .082057 L-atm/mol-K
25 C = 298.15 K
12 (2.5) = n (.082057) (298.15) n = 1.23 moles
