Answer:
The rows on the periodic table are called periods. All the elements in a period have valence electrons in the same shell. The number of valence electrons increases from left to right in the period. When the shell is full, a new row is started and the process repeats.

hope this helps..
From the information in the question, the E° and E for the cell is 0.00 V and 0.12 V.
Using the Nernst equation;
Ecell = E°cell - 0.0592/n log Q
We know that E°cell = 0.00 V since the anode and cathode are both made up of cadmium.
Substituting the given values into the Nernst equation;
Ecell = 0.00 V - 0.0592/2 log (1.0 × 10-5 M/0.100 M)
Ecell = 0.00 V - 0.0296 log(1 × 10^-4)
Ecell = 0.12 V

Answer:
The answer to your question is 2 moles
Explanation:
Data
mass of H₂O = 36 g
moles of H₂O = ?
Process
1.- Calculate the molar mass of water (H₂O)
H₂O = (1 x 2) + (16 x 1) = 2 + 16 = 18 g
2.- Use proportions and cross multiplication to find the answer.
18 g of H₂O ---------------- 1 mol
36 g of H₂O --------------- x
x = (36 x 1) / 18
x = 36/18
x = 2 moles
Answer:
0.258 mg of iron remains.
Explanation:
To solve this problem we can use the formula
M₂ = M₀ * 
Where M₂ is the mass remaining, M₀ is the initial mass, and t is time in days.
Using the data given by the problem:
M₂ = 2.000 mg * 
M₂ = 0.258 mg
