Answer:
Oxygen atom, because the partial negative charge is localized on the oxygen atom.
Explanation:
A cation is a positive ion, so to associate with it, would be necessary a negative ion, an anion. When the water dissociates, it will form and
.
So, oxygen has a negative charge, and in the molecule, the partial negative charge because it's more electronegative. Then, oxygen will be associated with the cation.
Answer : The volume of will be, 514.11 ml
Explanation :
The balanced chemical reaction will be,
First we have to calculate the mass of in tablet.
Now we have to calculate the moles of .
Molar mass of = 1 + 12 + 3(16) = 61 g/mole
Now we have to calculate the moles of .
From the balanced chemical reaction, we conclude that
As, 1 mole of react to give 1 mole of
So, 0.0202 mole of react to give 0.0202 mole of
The moles of = 0.0202 mole
Now we have to calculate the volume of by using ideal gas equation.
where,
P = pressure of gas = 1.00 atm
V = volume of gas = ?
T = temperature of gas =
n = number of moles of gas = 0.0202 mole
R = gas constant = 0.0821 L.atm/mole.K
Now put all the given values in the ideal gas equation, we get :
Therefore, the volume of will be, 514.11 ml
Explanation:
The graphite anodes are suspended into the brine. During electrolysis, Cl ions are oxidized at the anode and chlorine gas goes out of the cell, while sodium ions are reduced at the mercury cathode forming sodium amalgam. ... Hydrogen gas is obtained as a by–product at the cathode.
