Rule 1 states that the oxidation numbers of an atom in an element is always 0, so the oxidation number for Ca in the metal and O in O2 have oxidation numbers of zero
hope this helped :)

c₁=0.400 mol/l
v₁=100.0 ml = 0.1 l
c₁v₁=c₀v₀
v₀=c₁v₁/c₀
v(H₂O)=v₁-v₀
v₀=0.1*0.400/2=0.02 l = 20 ml
v(H₂O)=100 - 20 = 80 ml
It is necessary to mix 20 ml of the feed solution and 80 ml of water.
