How many milliliters of 0.0630 m edta are required to react with 50.0 ml of 0.0110 m cu2 ?
gizmo_the_mogwai [7]
Moles Cu+2 = M * V
                     =  0.05 L * 0.011  m
                     = 0.00055 moles

when the molar ratio of Cu2+: EDTA = 1:1 so moles od EDTa also =0.00055 moles

and when the Molarity of EDTa = 0.0630 M

∴ Volume of EDTA =  moles / Molarity
                 = 0.00055 / 0.0630
                 = 0.0087 L = 8.7 L

If a shell can hold a maximum of 32 electrons, what is the value of n?
olga2289 [7]
<span>Begin by classifying which energy level, and indirectly principal quantum number, n, resembles to the N shell. no. of orbitals =n2 In your case, the fourth energy level will contain n=4⇒no. of orbitals= 4^2=16 The number of subshells is given by the principal quantum number. no. of subshells=n In your case, the fourth energy level will have no. of subshells = 4 this is the answer to check: the fourth energy shell will can hold a thoroughgoing of no. of electrons=2⋅42=32 e−</span>
