(aii) Zymase

(b) -The strength of an acid

-The PH of the solution

(c) Fe + H\(_2\)SO\(_4\) -> FeSO\(_4\) + H2 mass of unreacted iron calculated below;

No. of moles of H\(_2\)SO\(_4\) = 10cm\(^3\)

Concentration = 1mol/dm\(^3\)

Amount = Vol x Concentration

= \(\frac{10}{100}\) x 1

= 0.01mol

1 mole of H\(_2\)SO\(_4\) = 1 mole of Fe

Mass of Fe reacted = 56 x 0.01g = 0.56g

Mass of unreacted Fe = (5.0 - 0.056)g = 4.44g
