How do electrons in a metallic bond behave?

Hello,

In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.

Hope this helps!!!! Happy Holidays!!!! (:

The hydrogen ion concentration is 1 × 10-7. What is the ph of this solution?

Naya [18.7K]

Answer:

The pH of the solution is 7

Explanation:

The pH is a measure of the acidity of the solutions. It is defined as the negative logarithm of the molar concentration of hydrogen ions (H⁺).

pH = - log [H⁺]

The hydrogen ion concentration of this solution is 1 × 10⁻⁷ M.

Hence:

pH = - log (1 × 10⁻⁷) = - (-7) = 7

This pH corresponds to a neutral solution (neither acid nor alkaline).

You should remember this relation bwtween pH and acidity/alkaliinity:

Low pH (0.0 or close) corresponds to strong acids
HIgh pH (14.0 or close) corresponds to strong bases
Acids have pH between 0.0 and 7.0
Bases have pH between 7.0 and 14.0

What is the total mass of solute in 1000. grams of a solution having a concentration of 5 parts per million?

Art [367]

50 grams or 50,000 mili grams is the mass of solute in 1000 grams of a solution having a concentration of 5 parts per million.

Explanation:

Total mass of solution = 1000 grams or 1000 ml since 1 gram = 1 ml

concentration is 5 parts per million ( 5 mg in 1000 ml solution or 0.005 gram in 1000 ml)

the formula used for parts per million:

parts per million = $\frac{mass of solute (mg)}{volume of solution}$

putting the values in the equation:

parts per million = $\frac{mass of solute}{volume of solvent}$

0.005 x 1000 = mass of solute

50 grams= mass of solute

converting this into mg

50,000 mg. is the total mass of solute in 5ppm of 1000 ml solution.
