Answer:
The answer to your question is: # of atoms = 2.42 x 10¹⁰
Explanation:
Data
radius = 248 pm
row = 6 cm long
Conversion
1 pm ------------------- 1 x 10 ⁻¹⁰ cm
248 pm -------------------- x
x = (248 x 1 x 10⁻¹⁰) / 1
x = 2.48 x 10⁻¹⁰ cm
Divide
# of atoms = 6 / 2.48 x 10⁻¹⁰
# of atoms = 2.42 x 10¹⁰

Answer:
(a) X electrode
(b) Y electrode
(c) Y electrode
(d) X electrode
(e) Y electrode
Explanation:
<em>A galvanic (voltaic) cell has the generic metals X and Y as electrodes. X is more reactive than Y, that is, X more readily reacts to form a cation than Y does.</em>
In the X electrode occurs the oxidation whereas in the Y electrode occurs the reduction.
Oxidation: X(s) → X⁺ⁿ(aq) + n e⁻
Reduction: Y⁺ˣ(aq) + x e⁻ → Y(s)
<em>Classify the descriptions by whether they apply to the X or Y electrode.
</em>
<em>(a) anode.</em> Is where the oxidation takes place (X electrode).
<em>(b) cathode.</em> Is where the reduction takes place (Y electrode).
<em>(c) electrons in the wire flow toward.</em> Electrons in the wire flow toward the cathode (Y electrode).
<em>(d) electrons in the wire flow away.</em> Electrons in the wire flow away from the anode (X electrode).
<em>(e) cations from salt bridge flow toward.</em> Cations from the salt bridge flow toward the cathode (Y electrode) to maintain the electroneutrality.
Fe (iron) has 26
protons,30 neutrons and 26 electrons. In order to calculate the binding energy,
first you need to find the total mass of all particles in the nucleus:
<span>
<span>26 x mass of proton + 30 x mass of neutron ( all in a.m.u.) =
say "m" </span></span>
<span>
Mass defect is m- 55.9207 amu, then convert it into grams and
put in equation E = mc2 to get binding energy of Fe.</span>
<span> Divide it by number of nucleons to get binding
energy per nucleon</span>.
