Answer:
Ionic bonds are formed between metals and nonmetals. The compatability of the metals and nonmetals is what makes them have a neutral charge as they cancel each other.
Eg: Using sodium chloride.
Na+ + Cl- > a neutral compound of NaCl without charges.
H2SO4 ---> 2H^+ + SO4^2-
Hence n H+ = 9 mols
Mass of H = nM = (9*1) = 9g
Alternately
mass of H2SO4= nM= 4.5*98= 441
Mass of H= mass h2so4 * molar mass of H/molar mass of h2so4
Mass of H= 441 * 2/98 = 9g

B
