Answer is: Kw of pure water at 50.0°C is <span>5.50 × 10-14</span><span>.
pH = 6.630.
pH = -log</span>[H⁺].
[H⁺] = 10∧(-pH).
[H⁺] = 10∧(-6.63) = 2.34·10⁻⁷ M.
[H⁺] · [OH⁻] = x.
Kw = ?.<span>
Kw = [H</span>⁺] · [OH⁻]. <span>
Kw = x².
Kw = (</span>2.34·10⁻⁷ M)².
Kw = 5.50·10⁻¹⁴ M².
Kw is ionic product of water.
Answer:
D metallic
Explanation:
The chemical bonding which rises from electrostatic attractive force between the conduction electrons and the positively charged metal ions is called metallic bonding.
<u>It is sharing of the free electrons among the structure of the positively charged ions which are known as cations.
</u>
<u>In this type of bonding, these free electrons freely move in the crystal mattice of the metal. </u>
The bonding accounts for properties of metals, such as ductility, strength, electrical and thermal conductivity and resistivity and luster.
Answer:
See explanation
Explanation:
I'm assuming you're asking about intensive properties. These properties only depend on the type of material, not the amount. Examples include color, temperature, boiling point, and hardness.
