Answer: 11.18atm
Explanation:Please see attachment for explanation
In a sample of H2SO4 that contain 200 S atom the number of hydrogen atoms would be 400 atoms
explanation
there are two moles of H2 in H2SO4 therefore by use of ratio between S:H2 which is 1:2 atoms therefore the atoms of hydrogen = 2 x200 = 400 atoms
Answer: Transition metal
Explanation: Copper is definitely a transition metal because the Cu2+ ion has an incomplete d level.
