The products of self-ionization of water are
Answers
The products of self-ionization of water are H3O+ or H+ and OH-
The auto-ionization constant of water is equal to the product of the concentration of H3O+ andOH- . The value of w depends only on temperature. It can be change according to the temperature.
OH- is the hydroxide ion and H+ is the hydronium ion.

Molarity NaOH = 0.1 M
Number of moles NaOH :
n = M * v
n = 0.1 * 0.054
n = 0.0054 moles of NaOH
Finally we calculate the number of moles of HCl in the solution from the stoichiometry of the reaction :
HCl + NaOH = NaCl + H₂O
1 mole HCl -------- 1 mole NaOH
? moles HCl ------- 0.0054 moles NaOH
moles HCl = 0.0054 * 1 /1
= 0.0054 moles of HCl
Volume of HCl = 125 mL / 1000 = 0.125 L
M ( HCl ) = n / V
M = 0.0054 / 0.125
= 0.0432 M

B.) If the solid is not conductive, the bonds are covalent.
C.) If the solid is conductive, the bonds are metallic.
D.) If the solid is not conductive, the bonds are metallic.
Answers
Answer is: C.) If the solid is conductive, the bonds are metallic.
1) Substances with ionic bond conduct an electric current in liquid, but not in solid state, because in liquids ions are mobile, contrary to solids where ions are fixed.
2) Substances with covalent bond not conduct an electric current in liquid and solid state, because they not have free ions or electrons.
3) Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons. Most metals have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.
Answer:C.) If the solid is conductive, the bonds are metallic.

Answer is: C) N.
Nitrogen (N) has greatest electronegativity.
Electronegativity (χ) is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.
Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.
Nitrogen has electronegativity χ = 3 and other elements have less.
has the greatest attraction for electrons in a chemical bond.
Further explanation:
Electronegativity:
It is the tendency of an atom to attract the shared electrons in the bond towards itself. More the electronegativity of the atom, higher will be its tendency to attract the bonding electrons towards itself. The electronegative atom develops a partial negative charge and the electropositive atom develops a partial positive charge.
Electronegativity trends in the periodic table:
Along the period, electronegativity increases due to the increase in the nuclear charge. This results in the strong attraction of electrons.
Down the group, electronegativity decreases due to an increase in the size of elements. This results in a lesser attraction between the nucleus and the electron.
All the given elements (As, Bi, N, P) are present in the same group of the periodic table. Nitrogen is present at the top of the group so it has the highest electronegativity among the given elements. Phosphorus is present below nitrogen but above As and Bi so its electronegativity is less than nitrogen but more than the remaining elements. Arsenic is present above Bi so it has more electronegativity than Bi. Bismuth is present at the bottom of the group so it has the least electronegativity among the given elements.
Therefore, nitrogen has the greatest tendency to attract electrons towards itself in a chemical bond.
